Title:
Multicast traffic not propating correctly over linux bridge
Status in linux package in Ubuntu:
Incomplete
Status in lxc package in Ubuntu:
Confirmed
Bug description:
There's a lot of supposition in the title of this bug but its
currently my best guess.
In this deployment, I have a number of services running in LXC
containers across multiple physical hosts; each service is clustered
across three units, all on separate physical hosts, using corosync and
pacemaker; when using multicast to support cluster communication, I
occasionally see a container drop out of the cluster and use its
isolation response (to shutdown all managed services); when using
unicast I've not yet see this same problem.
LXC containers are bridged to the main physical network using a linux
bridge:
eth0 <-> juju-br0 <-> vethXXX <-> | vethXXX |
All MTU's are standard (1500).
