IGMP Proxy Address already in use

fegauthier · July 29, 2020, 2:00pm

Hi guys! I have some problem with IGMP Proxy.

This is my configuration

show protocols igmp-proxy
 interface eth1.36 {
     alt-subnet 224.0.0.0/8
     alt-subnet 10.0.0.0/8
     role upstream
     threshold 1
 }
 interface eth3 {
     alt-subnet 192.168.5.0/24
     role downstream
     threshold 1
 }

There is my igmpproxy.conf

########################################################

#   The configuration file must define one upstream
#   interface, and one or more downstream interfaces.
#
#   If multicast traffic originates outside the
#   upstream subnet, the "altnet" option can be
#   used in order to define legal multicast sources.
#   (Se example...)
#
#   The "quickleave" should be used to avoid saturation
#   of the upstream link. The option should only
#   be used if it's absolutely nessecary to
#   accurately imitate just one Client.

IGMP Proxy doesn’t start. I got this message in the logs

I asked about the issue to the IGMP Proxy author on GitHub

Hi! I'm using Debian 10 and I'm having this issue. Jul 29 17:42:59 vyos ig…mpproxy[10347]: MC-Router API already in use; Errno(98): Address already in use Does anybody know why? This is my config file ``` quickleave # Configuration for eth1.36 (upstream interface) phyint eth1.36 upstream ratelimit 0 threshold 1 altnet 224.0.0.0/8 altnet 10.0.0.0/8 # Configuration for eth3 (downstream interface) phyint eth3 downstream ratelimit 0 threshold 1 altnet 192.168.5.0/24 ``` Thanks!

It means that igmpproxy (or some other multicast routing daemon) is already running.

Only one instance of multicast routing daemon can be started at the same time.

Is there any other multicast routing daemon that runs except igmpproxy?

Hi @fegauthier, we implemented IGMP/PIM support in rolling, it seems maybe a reason.

fegauthier · July 30, 2020, 12:08pm

Hi @Dmitry

Is there a way to disable IGMP/PIM ? I don’t use it, but I need IGMP Proxy to work to get IPTV.

This is the processes that are running

pimd seems to be running

Thanks!

I think now hot fix is only to set no in /etc/frr/daemon on pimd and kill pimd
This is bug, and it need to fix.

fegauthier · July 30, 2020, 12:20pm

It’s working! I set no in the daemon file. I did a reboot and everything’s working now.

Thanks!
