Notes from Jonathan: 117 | 118 | > I'd like to report some bugs in the current version of PimD-Dense, 119 | > which cause compilation to fail under Linux. In `defs.h`, external 120 | > variables that have already been defined are being re-defined, causing 121 | > the compilation to fail. In `pim.c`, there is a typing error - 122 | > `if->ip_len` is referred to, as opposed to `ip->ip_len`. I've 123 | > included the changes I've been using to fix these bugs. 124 | 125 | ### Fixes 126 | - Fixed entry timer initialization in `route.c:process_cache_miss()` 127 | - BUG FIX: fix TIMEOUT definitions in difs.h (bug report by Nidhi Bhaskar) 128 | (originally, if timer value less than 5 seconds, it won't become 0) 129 | - Fixed delay time for LAN prune scheduling to 4 seconds to comply with 130 | spec, which says that prunes should be delayed for time strictly 131 | greater than the maximum join delay of 3 seconds. 132 | - Fixed Prune timeout behavior: 133 | - Prune timeout now triggers graft 134 | - If prune and entry timeout simultaneously, the prune is timed out 135 | first, triggering an entry timer refresh. 136 | - Fixed Assert sending so that asserts sent from upstream routers 137 | without routes to the source send pref and metric of 0x7fffffff. 138 | 139 | 140 | June 19, 1998 141 | ------------- 142 | 143 | Modifications to comply with the latest PIM-DM spec revision: 144 | - Graft retransmission period is now 3 seconds 145 | - Random Join/Prune delay is 3 seconds 146 | 147 | Some still unresolved issues: 148 | - Upstream Address field in Graft and Graft-Ack 149 | 150 | 151 | v0.2.1.0-alpha15 - May 29, 1998 152 | ------------------------------- 153 | 154 | Synched in fixes from Pavlin's pimd-2.1.0-alpha15: 155 | 156 | - Bug fixes related to NetBSD, thanks to Heiko W.Rupp 157 | - `MRT_PIM` completely replaced by `MRT_ASSERT` 158 | 159 | 160 | v0.2.1.0-alpha11 - May 29, 1998 161 | ------------------------------- 162 | 163 | This is the first release of the the PIM Dense-Mode version of pimd. 164 | 165 | For now, I have simply prepended "0." onto the version number for Pavlin 166 | Ivanov Radoslavov's Sparse-Mode pimd, from which this code was derived. 167 | A new 1.0.x-alpha version number will be assigned upon the initial 168 | public release of this code. 169 | 170 | 171 | [UNRELEASED]: https://github.com/troglobit/pimd-dense/compare/2.1.1...HEAD 172 | [v2.1.1]: https://github.com/troglobit/pimd-dense/compare/2.1.0...2.1.1 173 | [v2.1.0]: https://github.com/troglobit/pimd-dense/compare/0.2.1.0-beta1...2.1.0 174 | [v0.2.1.0-beta1]: https://github.com/troglobit/pimd-dense/compare/0.2.1.0-alpha21...0.2.1.0-beta1 175 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Copyright (c) 1998 by the University of Oregon. 2 | All rights reserved. 3 | 4 | Permission to use, copy, modify, and distribute this software and its 5 | documentation in source and binary forms for lawful purposes and without 6 | fee is hereby granted, provided that the above copyright notice appear 7 | in all copies and that both the copyright notice and this permission 8 | notice appear in supporting documentation, and that any documentation, 9 | advertising materials, and other materials related to such distribution 10 | and use acknowledge that the software was developed by the University of 11 | Oregon.

Later revised in [RFC3973][], which pimdd 10 | does not (yet) fully support. 11 | 12 | PIM-DM is similar to DVRMP ([mrouted][]), they are both flood-and-prune 13 | multicast routing protocols, but unlike DVMRP, PIM implementations rely 14 | on the underlying unicast routes to be established already. 15 | 16 | This GitHub project is an attempt at reviving pimdd. The latest code on 17 | the master branch has been infused with fresh DNA strands from the 18 | [pimd][] project, including a netlink back-end to read the unicast 19 | routing table, and full IGMPv3 support (ASM). 20 | 21 | > **HELP NEEDED:** The project needs more volunteers to test and update 22 | > `pimdd` to RFC3973. 23 | 24 | 25 | Running pimdd 26 | ------------- 27 | 28 | If you have more than one router, you need to have unicast routing set 29 | up already between all subnets. Usually an IGP like OSPF or even RIP 30 | is used for this. Then start pimdd as root, it backgrounds itself as 31 | a proper UNIX daemon: 32 | 33 | pimdd 34 | 35 | Use the `pimctl` control tool (shared with pimd) to query status. The 36 | project also ships a systemd unit file that allows for customization of 37 | command line arguments using an environment file: `/etc/default/pimdd`. 38 | 39 | See the manual pages for details on command line options, config file 40 | settings, and the `pimctl` control tool: 41 | 42 | - https://man.troglobit.com/man8/pimdd.8.html 43 | - https://man.troglobit.com/man8/pimctl.8.html 44 | - https://man.troglobit.com/man5/pimdd.conf.5.html 45 | 46 | To help out with development, or tracking down bugs, it is recommended 47 | to run pimdd in debug mode. Since there are many debug messages, you 48 | can specify only a subset of the messages to be printed out: 49 | 50 | ``` 51 | Usage: pimdd [-hnpqrsv] [-d SYS[,SYS]] [-f FILE] [-l LVL] [-w SEC] 52 | 53 | -d SYS Enable debug of subsystem(s) 54 | -f FILE Configuration file, default: /etc/pimdd.conf 55 | -h This help text 56 | -i NAME Identity for config + PID file, and syslog, default: pimdd 57 | -l LVL Set log level: none, err, notice (default), info, debug 58 | -n Run in foreground, do not detach from calling terminal 59 | -p FILE Override PID file, default is based on identity, -i 60 | -s Use syslog, default unless running in foreground, -n 61 | -u FILE Override UNIX domain socket, default based on identity, -i 62 | -v Show program version 63 | -w SEC Initial startup delay before probing interfaces 64 | 65 | Available subystems for debug: 66 | all, igmp, groups, igmp_proto, igmp_timers, igmp_members, interfaces, 67 | kernel, mfc, neighbors, pkt, rsrr, pim, asserts, bsr, detail, graft, hello, 68 | registers, routes, pim_routes, jp, pim_timers, rpf, timers, timeout, trace 69 | ``` 70 | 71 | If you want to see all messages, use `pimdd -d all`. When debugging 72 | `pimdd`, it is recommended to run in foreground as well. 73 | 74 | 75 | Build & Install 76 | --------------- 77 | 78 | When building from a released tarball, the configure script is bundled 79 | and you do not need to do anything special (see below for building from 80 | GIT). The Makefile supports de facto standard settings and environment 81 | variables such as `--prefix=PATH` and `DESTDIR=` for the install 82 | process. E.g., to install pimd to `/usr` instead of the default 83 | `/usr/local`, but redirect install to a package directory in `/tmp`: 84 | 85 | ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var 86 | make 87 | make DESTDIR=/tmp/pimd-dense-1.0.0 install-strip 88 | 89 | 90 | Building from GIT 91 | ----------------- 92 | 93 | If you want to contribute, or simply just try out the latest but 94 | unreleased features, then you need to know a few things about the 95 | [GNU build system][build]: 96 | 97 | - `configure.ac` and a per-directory `Makefile.am` are key files 98 | - `configure` and `Makefile.in` are generated from `autogen.sh` 99 | - `Makefile` is generated by `configure` script 100 | 101 | To build from GIT you first need to clone the repository and run the 102 | `autogen.sh` script. This requires `automake` and `autoconf` to be 103 | installed on your system. 104 | 105 | git clone https://github.com/troglobit/pimd-dense.git 106 | cd pimd-dense/ 107 | ./autogen.sh 108 | ./configure && make 109 | 110 | GIT sources are a moving target and are not recommended for production 111 | systems, unless you know what you are doing! 112 | 113 | 114 | Origin & References 115 | ------------------- 116 | 117 | This code is old and was sort of dead and forgotten. The only project 118 | that kept it running was FreeBSD in their ports collection. As such it 119 | was included in the BSD Router Project. 120 | 121 | pimdd was written by Kurt Windisch when he was at University of Oregon. 122 | It is based on the PIM sparse-mode daemon, pimd, which in turn is based 123 | on the DVMRP daemon mrouted. 124 | 125 | pimdd is covered by [LICENSE](LICENSE), Copyright 1998 the University of 126 | Oregon. 127 | 128 | pimd is covered by [LICENSE.pimd](doc/LICENSE.pimd), Copyright 1998-2001 129 | University of Southern California. 130 | 131 | mrouted is covered by [LICENSE.mrouted](doc/LICENSE.mrouted), Copyright 132 | 2002 The Board of Trustees of Leland Stanford Junior University 133 | 134 | [mrouted]: https://github.com/troglobit/mrouted 135 | [pimd]: https://github.com/troglobit/pimd 136 | [draft]: https://github.com/troglobit/pimd-dense/blob/master/doc/draft-ietf-idmr-pim-dm-spec-05.txt 137 | [RFC3973]: https://tools.ietf.org/html/rfc3973 138 | [License]: https://en.wikipedia.org/wiki/BSD_licenses 139 | [Badge]: https://img.shields.io/badge/License-BSD%203--Clause-blue.svg 140 | [GitHub]: https://github.com/troglobit/pimd-dense/actions/workflows/build.yml/ 141 | [CIstat]: https://github.com/troglobit/pimd-dense/actions/workflows/build.yml/badge.svg 142 | [build]: https://autotools.io/ 143 | [Scan]: https://scan.coverity.com/projects/troglobit-pimd-dense 144 | [Cstat]: https://scan.coverity.com/projects/21569/badge.svg 145 | -------------------------------------------------------------------------------- /autogen.sh: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | autoreconf -W portability -visfm 4 | -------------------------------------------------------------------------------- /configure.ac: -------------------------------------------------------------------------------- 1 | AC_PREREQ(2.61) 2 | AC_INIT([pimdd], [2.1.1], [https://github.com/troglobit/pimd-dense/issues], 3 | [pimd-dense], [https://github.com/troglobit/pimd-dense/]) 4 | AC_CONFIG_AUX_DIR(aux) 5 | AM_INIT_AUTOMAKE([1.11 foreign]) 6 | AM_SILENT_RULES([yes]) 7 | 8 | AC_CONFIG_SRCDIR([src/main.c]) 9 | AC_CONFIG_HEADERS([config.h]) 10 | AC_CONFIG_FILES([Makefile include/Makefile man/Makefile src/Makefile test/Makefile pimdd.service]) 11 | 12 | # Check for standard programs, headers, and functions 13 | AC_PROG_CC 14 | AC_PROG_INSTALL 15 | AC_PROG_YACC 16 | 17 | # Check build host, differnt for each operating system 18 | AC_CANONICAL_HOST 19 | 20 | case $host_os in 21 | dragonfly*) 22 | CPPFLAGS="-I../include/dragonfly" 23 | ;; 24 | netbsd*) 25 | CPPFLAGS="$CPPFLAGS -D_OPENBSD_SOURCE" 26 | ;; 27 | solaris2.5) 28 | CPPFLAGS="-DSYSV -DSunOS=55 -I../include/sunos-gcc" 29 | LIBS="-lsocket -lnsl" 30 | ;; 31 | solaris2.6|solaris2.7|solaris2.8|solaris2.9|solaris2.10|solaris2.11) 32 | CPPFLAGS="-DSYSV -DSunOS=56 -I../include/sunos-gcc" 33 | LIBS="-lsocket -lnsl" 34 | ;; 35 | linux*) 36 | # -D_GNU_SOURCE Use GNU extensions, where possible (GLIBC) 37 | # -D_BSD_SOURCE Use functions derived from 4.3 BSD Unix rather than POSIX.1 38 | # In GLIBC >= v2.20 this is replaced with -D_DEFAULT_SOURCE, 39 | # but to build on older GLIBC systems we now need both ... 40 | CPPFLAGS="-D_BSD_SOURCE -D_DEFAULT_SOURCE -D_GNU_SOURCE" 41 | ;; 42 | *) 43 | ;; 44 | esac 45 | 46 | # Required to check for libsystemd-dev 47 | PKG_PROG_PKG_CONFIG 48 | 49 | AC_CHECK_HEADERS([fcntl.h netinet/pim.h net/if_dl.h sys/time.h sys/ioctl.h linux/netlink.h termios.h]) 50 | AC_CHECK_HEADERS([net/if.h], [], [], [ 51 | #include 52 | #ifdef STDC_HEADERS 53 | # include 54 | # include 55 | #else 56 | # ifdef HAVE_STDLIB_H 57 | # include 58 | # endif 59 | #endif 60 | #ifdef HAVE_SYS_SOCKET_H 61 | # include 62 | #endif]) 63 | 64 | # Check for usually missing API's, which we can replace 65 | AC_REPLACE_FUNCS([strlcpy strlcat tempfile]) 66 | AC_CONFIG_LIBOBJ_DIR([lib]) 67 | 68 | AC_ARG_ENABLE(rsrr, 69 | AS_HELP_STRING([--enable-rsrr], [Routing Support for Resource Reservation 70 | currently used by RSVP (EXPERIMENTAL).

If you choose to use it, send any 9 | comments or bug reports to kurtw@antc.uoregon.edu. 10 | 11 | PimD-Dense should compile and run on most UNIX varieties, including 12 | FreeBSD, BSDI, NetBSD, SunOS, IRIX, Solaris 2.5, Solaris 2.6, and Linux 13 | (however it has not yet been tested on all these). 14 | 15 | The software and information may be obtained from the website of 16 | the University of Oregon's Advanced Network Technology Center (ANTC). 17 | 18 | For more information: 19 | http://www.antc.uoregon.edu/PIMDM/pimd-dense.html 20 | 21 | For anonymous FTP: 22 | ftp://ns.uoregon.edu/pub/src/pimd-dense.tar.gz 23 | 24 | ----------------------------------------------------------------------- 25 | Kurt Windisch kurtw@antc.uoregon.edu 26 | Network Engineer/Research Asst.

DR does not go to highest IP when new neighbor appears!!! 33 | 34 | * Sync with changes in the lastest Sparse-Mode pimd release 35 | Pimd-dense is now synched up to alpha21. 36 | 37 | * The mrtentry preference/metrics should be used to indicate the 38 | distance/metric for the upstream assert winner for comparison with 39 | assert messages received from upstream. When lacking upstream 40 | distance/metric info (before assert or after assert times out), 41 | should the mrtentry pref/metric be set to 0/0 (or some other 42 | arbitrary values) or to the distance/metric of the source for the 43 | local router (which should always be greater than those 44 | received from asserts)??? I think the current scheme is okay: 45 | set to 0/0 when allocating mrtentry and source distance/metric when 46 | creating route before assert or when timing out assert. 47 | 48 | ------- 49 | * Use NetBSD's definition for IPADDR (netinet/in.h): 50 | #ifdef _KERNEL 51 | #define __IPADDR(x) ((u_int32_t) htonl((u_int32_t)(x))) 52 | #else 53 | #define __IPADDR(x) ((u_int32_t)(x)) 54 | #endif 55 | 56 | * Check whether the kernel code sends CACHE_MISS and WRONG_IIF for 57 | the LAN-scoped addresses 58 | 59 | * If a new interface is configured, include it automatically 60 | 61 | * Don't create routing entries for local link scoped groups 62 | 63 | * Implement adm. scoped filters 64 | 65 | * Do more precise error check for the received PIM messages. In most cases, 66 | the whole message must be parsed completely before starting processing it. 67 | 68 | * Clean up the debugging messages. 69 | 70 | * Use Patricia tree to search the routing table 71 | (There is a nice paper in Sigcomm '97 about fast routing tables 72 | implementation, so need to check it as well) 73 | 74 | * Change all countdown timers to events timeout (callout.c) 75 | (The current implementation is very unefficient if the routing table becomes 76 | very large) 77 | 78 | * Fix the code allowing interface UP/DOWN without restarting pimd. 79 | 80 | * Test the RSRR (RSVP support) code 81 | 82 | * Send Initial_Reply RSRR message if the interfaces detected by pimd change 83 | -------------------------------------------------------------------------------- /doc/DEVELOPMENT.NOTES: -------------------------------------------------------------------------------- 1 | Dense-mode TODO: 2 | ----------------- 3 | - Go through Pavlin's notes in BUGS.TODO and resolve 4 | 5 | TESTING/BUGS 6 | ------------ 7 | 8 | 9 | NOTES 10 | ----- 11 | -------------------------------------------------------------------------------- /doc/IPC.md: -------------------------------------------------------------------------------- 1 | pimctl ipc interface 2 | ==================== 3 | 4 | pimdd share pimctl with pimd.

Apply the PIM kernel patches, recompile, reboot. 21 | These contain necessary bug fixes to the ipmroute kernel code as well 22 | as stuff needed only for PIM-SM. 23 | 24 | 2. Copy pimdd.conf to /etc and edit as appropriate. Disable the interfaces 25 | you don't need. Note that you need at least 2 physical interfaces enabled. 26 | 27 | 3. Edit Makefile by uncommenting the line(s) corresponding to your platform. 28 | 29 | 4. Recompile pimdd (you need to have the 'include' files patches applied) 30 | 31 | 5. Run pimdd as a root. It is highly recommended to run it in debug mode. 32 | Because there are many debug messages, you can specify only a subset of 33 | the messages to be printed out: 34 | 35 | usage: pimdd [-hv] [-f configfile] [-d debug_level[,debug_level]] 36 | 37 | Valid debug levels: dvmrp_prunes, dvmrp_mrt, dvmrp_neighbors, 38 | dvmrp_timers, igmp_proto, igmp_timers, igmp_members, trace, 39 | timeout, pkt, interfaces, kernel, cache, rsrr, pim_hello, 40 | pim_register, pim_join_prune, pim_graft, pim_bootstrap, 41 | pim_asserts, pim_routes, pim_timers, pim_rpf 42 | 43 | If you want to see all messages, use `pimd -d all` 44 | 45 | 6. There are plenty of bugs, some of them known (check BUGS.TODO), 46 | some of them unknown, so your bug reports are mroe than welcome. 47 | 48 | Kurt Windisch 49 | kurtw@antc.uoregon.edu 50 | 51 | ACKNOWLEDGEMENTS: 52 | 53 | * This pimd code was mostly written by Pavlin Ivanov Radoslavov 54 | (pavlin@catarina.usc.edu) and Ahmed Helmy (ahelmy@catarina.usc.edu), 55 | before being heavily modified by myself. 56 | 57 | * The PIM kernel modifications and pimd itself were originally written by 58 | Ahmed Helmy (ahelmy@catarina.usc.edu) as a summer intern in SGI. 59 | 60 | * The "up to the March '97 I-D spec" + RSVP support pimd version was done 61 | during Pavlin's summer'97 intern in Sun Microsystems under Michael Speer's 62 | supervision. 63 | 64 | * BSDI 3.0/3.1 support + various improvements and bug reports 65 | by Hitoshi Asaeda (asaeda@yamato.ibm.co.jp). 66 | 67 | * Bug reports and SGI tests by Nidhi Bhaskar (nidhi@cho-oyu.engr.sgi.com). 68 | 69 | * Bug reports and SunOS tests by Isabelle Girard (girardi@rc.bel.alcatel.be) 70 | and Dirk Ooms (oomsd@rc.bel.alcatel.be) 71 | 72 | * NetBSD-1.3 compilation support (both for pimd and the kernel mods) and 73 | bug reports by Heiko W.Rupp 74 | 75 | * Thanks to the FreeBSD team and particularly to the 76 | freebsd-hackers mailing list participants for the help 77 | with the real-time debugging of the FreeBSD kernel. 78 | 79 | -------------------------------------------------------------------------------- /doc/RELEASE.NOTES: -------------------------------------------------------------------------------- 1 | Second Pre-release December 31, 1998 (Happy New Year) 2 | 3 | * Fixed a variety of bugs and updated the implementation to comply 4 | with some sublte points and revisions of the PIM-DM specification. 5 | 6 | * Also synch'ed with the latest pimd from Pavlin and added patches 7 | for Linux, which were contributed by Jonathan Day . 8 | Thanks Jonathan. 9 | 10 | 11 | First Pre-release June 5, 1997 12 | 13 | * Pimd-dense requires kernel patches to the current ip_mroute kernel 14 | in order to operate correctly. This is due to bugs in the ipmroute 15 | kernel code currently being distributed (at least for FreeBSD). 16 | I've tested pimdd with both Rusty's GateD patches (to be depricated) 17 | and Pavlin's combined patches, which are available at: 18 | ftp://catarina.usc.edu/pub/pim/pimd/experimental/one-pimd-gated-kernel 19 | It should also work with any of the other recent patch kits that Pavlin 20 | has produced for use with Sparse-mode pimd. 21 | 22 | * Since pimd cannot reliably get distance and metric info from the kernel 23 | a configuration option is provided to specify a distance with which to 24 | advertise sources when sending PIM-Assert messages. The phyint command 25 | in pimd.conf allows you to specify a default distance for each interface. 26 | If no distance is specified, it defaults to 101, which is high enough that 27 | default distance advertised by either Cisco or Gated routers (both having 28 | better information on unicast routes) will win over pimd distances. 29 | Directly connected sources will always be asserted with a distance of 0. 30 | 31 | * Because unicast routes are obtained from the kernel, only the preferred 32 | route is available. pimd cannot determine, or handle, the existence of 33 | equal-cost-multipaths, and thus does not implement the addressing of 34 | joins and prunes to 0.0.0.0. 35 | 36 | * RSRR support is currently rough and completely untested. 37 | 38 | -------------------------------------------------------------------------------- /doc/TESTING: -------------------------------------------------------------------------------- 1 | 2 | Neighbor establishment passes manual 3 | Neighbor addition w/ state (potential flood) passes manual 4 | Neighbor timeout passes manual 5 | Neighbor timeout w/ state (potential prune) passes manual 6 | Cache miss-create S,G state passes manual 7 | Packet forwarding on flood (fwd to nbr) passes manual 8 | Packet forwarding on flood (fwd to host) passes manual 9 | MRT entry refresh on data passes manual 10 | MRT entry timeout passes manual 11 | IGMP group membership caching w/o state passes manual 12 | IGMP group membership report w/ state passes manual 13 | IGMP group membership leave w/ state passes manual 14 | passes manual 15 | passes manual 16 | passes manual 17 | 18 | 19 | 20 | -------------------------------------------------------------------------------- /doc/pimd-dense.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | PIM-Dense Routing Daemon Software 4 | 5 | 6 |

14 | 15 | Pimd-dense is a lightweight, stand-alone PIM-Dense Mode 16 | implementation that may be freely deployed or distributed. Pimd-Dense 17 | implements the full 18 | PIM-DM specification with a few exceptions 19 | noted in the Release Notes. 20 |

21 | 22 | The code from Pimd-dense is heavily based on the PIM-Sparse Mode daemon 23 | implementation by Puneet Sharma and Charley Liu (USC), Ahmed Helmy (SGI/USC), 24 | and Pavlin Ivanov Radoslavov (USC). For more info on PimD-Sparse, see the 25 | PIM Home Page at USC

26 | 27 | Use of PimD-Dense for multicast routing requires a separate facility for 28 | unicast routing such as (1) static routes via the UNIX route command, 29 | (2) RIP routes via the standard UNIX routed routing daemon, or 30 | (3) other dynamic unicast routing protocols such as those provided by the 31 | GateD multiprotocol routing daemon.

The Software

35 | 36 | PimD-Dense is currently ALPHA-version software that yet requires 37 | extensive testing. If you choose to use it, information about any 38 | bugs or problems sent to 39 | kurtw@antc.uoregon.edu would be 40 | greatly appreciated and will be investigated ASAP.

41 | 42 | PimD-Dense should compile and run on most UNIX varieties, including 43 | FreeBSD, BSDI, NetBSD, SunOS, IRIX, Solaris 2.5, Solaris 2.6, and Linux 44 | (however it has not yet been tested on all these).

45 | 46 | Many current version of the IP MRouting kernel code requires patches 47 | to correct certain bugs in order to work correctly with PimD-Dense. 48 | Before using PimD-Dense, you should apply one of the current 49 | patches available for PimD-Sparse from USC's 50 | 51 | PIM FTP site. Several are available.

Testing

66 | In the future, a suite of test scripts will be included that will test 67 | the basic functionality of this, or other, PIM-DM implemenations. 68 | This test suite will use George (Rusty) Eddy's 69 | PKT toolkit. 70 | 71 |

Commands can be abbreviated to the minimum unambiguous prefix; 48 | for example, 49 | .Cm s in 50 | for 51 | .Cm show interface . 52 | .Sh OPTIONS 53 | This program follows the usual UNIX command line syntax, with long 54 | options starting with two dashes (`-'). The options are as follows: 55 | .Bl -tag -width Ds 56 | .It Fl h, -help 57 | Show usage instructions and exit. 58 | .It Fl i, -ident Ar NAME 59 | Connect to named PIM daemon instance.

It locates other PIM-DM capable routers directly reachable 20 | via those interfaces. 21 | .Pp 22 | .Nm pimdd 23 | will not start with less than two enabled virtual interfaces (VIFs). A 24 | VIF is either a physical multicast-capable interface or a tunnel. To 25 | override the default settings, for example to disable some interfaces 26 | from being used, configuration commands may be placed in 27 | .Pa /etc/pimdd.conf . 28 | .Pp 29 | The file format is relatively free-form: whitespace (including newlines) 30 | is not significant. However, the order of some statements are 31 | important, more on this below. 32 | .Pp 33 | By default, 34 | .Nm pimdd 35 | runs on all multicast capable interfaces. The 36 | .Cm phyint 37 | setting can be used to control this behavior. 38 | .Pp 39 | .Bl -tag -offset indent -width 1n 40 | .It Cm assert-timeout Ao Ar 5-210 Ac 41 | .It Cm default-route-distance Ao Ar 1-255 Ac 42 | .It Cm default-route-metric Ao Ar 1-1024 Ac 43 | .It Cm no phyint 44 | .It Cm phyint Ao Ar address | Ar ifname Ac Oo Cm enable | disable Oc Oo Cm igmpv2 | igmpv3 Oc Oo Cm distance Ao Ar 1-255 Ac Oc Oo Cm metric Ao Ar 1-1024 Ac Oc 45 | .El 46 | .Pp 47 | The PIM assert mechanism arbitrates the forwarder of multicast when 48 | there are more than one router with the same (S,G) pair for a given 49 | destination LAN. The winner of an assert is the router with either 50 | the best (unicast) protocol distance (called metric preference in 51 | the RFC), or the best metric if the distance is the same, or, as a 52 | tiebreaker, the highest IP address. The loser of an asser election 53 | prunes its outbound interface from forwarding and starts an assert 54 | timer, in case the active forwarder is lost. The 55 | .Cm assert-timeout 56 | can be used to tune the PIM assert timer to a value between 5 to 210 57 | seconds, default: 180 sec. 58 | .Pp 59 | The 60 | .Cm default-route-distance 61 | option has nothing to do with the system default route, it is rather the 62 | default value for the unicast routing protocol's administrative 63 | distance. It is used in PIM Assert elections to determine upstream 64 | routers. Currently 65 | .Nm 66 | cannot obtain the admin distance and metric from the unicast routing 67 | protocols, so a default routing protocol distance (the RFC confusingly 68 | refers to this as 69 | .Em metric prefererence ) 70 | may be configured. In a PIM Assert election, the router advertising the 71 | lowest assert preference will be selected as the forwarder and upstream 72 | router for the LAN. Setting 101 should be sufficiently high so that 73 | asserts from Cisco or other routers preferred over 74 | .Nm . 75 | .Pp 76 | It is recommended that distances be set such that metrics are never 77 | consulted. However, default routing metrics may also be set using the 78 | .Cm default-route-metric 79 | option. (Again, this has nothing to do with the system default route.) 80 | This item sets the cost for sending data through this router. You want 81 | only PIM-DM data to go to this daemon; so once again, a high value is 82 | recommended to prevent accidental usage. The preferred default value is 83 | 1024. Both defaults can be overridden per phyint, so learned routes, or 84 | PIM Asserts use the phyint's values. 85 | .Pp 86 | Please also note that PIM Assert elections are not the same as the DR 87 | election. The PIM Assert election determines the active multicast 88 | forwarder, whereas the DR election determines the active PIM router. 89 | .Pp 90 | The 91 | .Nm phyint 92 | setting refers to a physical interface and must come after the 93 | .Cm default-route-metric 94 | and 95 | .Cm default-route-distance 96 | settings in the configuration file. Select the interface by its IP 97 | .Ar address 98 | or name. If you just want to activate this interface with default 99 | values, you don't need to put anything else on the line. However, there 100 | are some additional settings: 101 | .Pp 102 | .Bl -bullet -offset indent -width 1n -compact 103 | .It 104 | .Cm enable : 105 | Enable an interface for PIM. Used after the 106 | .Cm no phyint 107 | directive. 108 | .It 109 | .Cm disable : 110 | Do not use this interface in 111 | .Nm . 112 | .It 113 | .Cm igmpv2 | igmpv3 : 114 | Force interface in specific IGMP version. Default: 115 | .Cm igmpv3 . 116 | .It 117 | .Cm distance Ao Ar 1-255 Ac : 118 | Use this to override the 119 | .Nm default-route-distance 120 | (101) on this 121 | .Nm phyint 122 | in PIM Assert elections. 123 | .It 124 | .Cm metric Ao Ar 1-1024 Ac : 125 | The cost of sending data through this interface. Defaults to 126 | .Nm default-route-metric 127 | (1024) if not assigned. 128 | .El 129 | .Pp 130 | Add one 131 | .Nm phyint 132 | line per interface on this router.
