[Bug 1402763] Re: Multicast traffic not propating correctly over linux bridge

[James Page]

I've done a bit more testing, and here are my observations:

1) rebooting a container internally/stop-start externally using lxc-*

Works OK - container re-joins the corosync cluster just fine.

2) rebooting the physical host

Fails - containers never re-join the corosync cluster and perform the
configured isolation response which is to stop everything.

That said, if I reconfigure the cluster to using a new multicast
address, the cluster reforms OK.

So it would appear that cross server multicast is not being restored on
a physical server reboot; I guess this could be something todo with
switch configuration as well.
