IGMPv3 not working #48

Closed greenpau closed 9 years ago

greenpau commented 9 years ago

Configured all interfaces to use IGPMv3 via procfs. e.g. 

echo 3 > /proc/sys/net/ipv4/conf/all/force_igmp_version

note: i changed this value on all interfaces.

On the wire:

[root@ip-192-168-16-66 ~]# tshark -i tun1759 -f "igmp"
Running as user "root" and group "root". This could be dangerous.

The issues is that I am still using IGMPv2. Any ideas how to force IGMPv3?

Running pimd/mrouted means starting a multicast router. In UNIX kernels this means userspace takes on the role of sending IGMP/MLD queries. The pimd master currently only supports IGMPv2, but in pull request #36 (which I've still not completed my audit of) IGMPv3 is included.

I'm expecting to merge PR #36 within a few weeks, it's simply been too much to do at work (and life) currently.

@troglobit , thank you for the response! :smile: Will wait for the merge.

Support for IGMPv3 merged for the upcoming v2.3.0 release. It is now the default on all phyint interfaces (use new igmpv2 option to a phyint to force v2 instead).

I have tested it with Linux (Ubuntu 15.04), OpenBSD 5.7 and NetBSD 6.1.5, only ASM though, not SSM.
