      I updated my pfsense instance to latest version on May 2nd.
      Now IGMPProxy is not starting anymore.
      The error i get:

      MRT_ADD_VIF; Errno(48): Address already in use

      When i try to start it from the commandline i get:

      When i remove igb2.44 from the config it starts but is not usable.
      This config is needed to be able to use IP TV from my provider.

      How can i solve this or is it a bug?

        Debugging this gives me the feeling IGMPProxy is not the problem but pfsense is as i am trying to get PIMD configured and get the same error:

        pimd[68557]: Failed adding VIF 1 (MRT_ADD_VIF) for iface igb2.4: Address already in use

        If there is information missing please let me know.

          Reading https://github.com/troglobit/smcroute/issues/36#issuecomment-221486714

          Now, what is a VIF? Multicast routing does not use your regular interfaces but creates virtual interfaces that multicast routes then operate on. It may sound a bit weird, and trust me it is. If these VIF's cannot be created (as indicated by the three first log messages), then multicast routing will not work. I have no idea why it doesn't work for you, my guess was the ttl-threshold setting you had set, maybe that new feature, introduced in v2.1.0, somehow doesn't work on the CentOS 6 kernel, I don't even know what kernel version is used ... maybe downgrading to v2.0.0 would work better for you, or stripping down the configuration file.

          Makes me think igmp proxy is not able to create a vif.

            have exactly the same issue since this update.. reverting to an older version (april) resolves the issue, not sure whats causing it.. similar debug input btw and pretty basic config. Even if I remove the subnets from the upstream interface it states MRT_ADD_VIF; Errno(48): Address already in use.. changing ratelimit or threshold no effect either.

            Same issue with pimd indeed so I think pfsense broke it somehow.. not sure if it's kernel related as the april versions were also freebsd 12.1 based but perhaps a previous kernel.

              Would be nice to verify if it should be logged as a bug.

                        @maartenhendrix hi thanks but i don't quite understand what the suggestion is. i tried to update pimd and it all seems up to date. i disabled the service and rebooted and when it came back up re-enabled the service but pimd still doesnt start. is that what is being suggested? cheers!

                            ok, thanks. i made some progress based on your info. there's some other issues but i've worked around them. on 2.4.3 i was able to have the default action as to bind to all interfaces and then disable WAN and any others you don't want PIMD running on. this won't work on 2.5 but reversing the logic and restarting after every config change gets it working. cheers!

                              A couple of month ago, I finally managed to get multicast working on 2.4.5 with the 'new' PIMD package (despite a lot of effort I never managed to get IGMP-proxy working).

                              However, than ...

                              1. I did a try to migrate to 2.5.0, that did not work at all due to a problem after reboot (see another post), but I also noticed that PIMD was not longer working ☹
                              2. so I switched back to 2.4.5 (PIMD working again). However ...... then I made a config change splitting a LAGG in two normal interfaces. That should not affect PIMD, I would say, but it did. Even worse I do not managed to get PIMD working again still using 2.4.5 ☹

                              My strong impression is that there issues below the (free bsd?) surface affecting PIMD in both 2.4.5. and 2.5.0. !!

                              There are a couple of lines in the logging which are ..... let's say strange. Note I use "bind to none" as default! Here log messages during startup (read bottom up).

                              • and then the result, nu vifs, so no working PIMD

                                Hello,

                                The more I am trying to get pimd running, the more I am wondering it the FreeBSD setup is correct! Note that I am not a FreeBSD expert, and I am also not aware of NetGate's low level settings. But I do have some doubts e.g. related to:

                                • some where there should be ^ip_mroute_load="yes"^ (loader.conf ??)
                                • And the multicast interface flag is not set by default .....
                                  so in the interface setup there should be things like
                                  ^sudo ip link set ix0 multicast on^ and
                                  ^sudo ip link set ix1 multicast on^

                                Perhaps other config issues too ....

                                Louis

                                  From the Diagnostics / Command Prompt menu, I used ^ifconfig^

                                  So, my verdict in the previous mail was probably not correct.

                                  No idea what is wrong, one thing is for sure .... it does not work ☹

                                    Hello,

                                    I just discoverd that when I replace the interface names in /var/etc/pimdpimd.conf with the corresponding IP-addresses, a couple of error messages disappear.

                                    However the issue that not all (vlan)interfaces have vifs stay, and at the end of the startup PIMD is still not running due to "Cannot forward: no enabled vifs"

                                    also note that i am missing ^mrouting^ and my feelings are not changes since I created bug #9631 a year ago.
