[Bug 637127] Re: TTL is one - prevents multicast routing
Bug reported upstream - thanks for the lead on the bug tracker. Couldn't
find it earlier.
The network is configured as follows:
Steps to Reproduce:
1. Two hosts linked by an ethernet
2. Libvirt in routed mode.
3. Virtual machines sat on a 10.x.x.x/30 subnet.
4. Unicast routing in place (I'm using bird and OSPF).
5. Multicast routing in place (pimd).
6. Libvirt configured so that it doesn't filter multicast!
7. Tested as working with ssmping
