Does Martin have updated all nodes of a cluster ?
If not, it's possible that physical switch (with igmp snooping) allow only traffic between non-updated nodes with linux bridge with igmp snooping enabled and block other nodes.
But In the case, the multicast traffic should works between non updated nodes.

Martin updated 2 clusters, and now I get strange TOTEM error - corosync does not work.
Mar 8 14:30:23 hp1 corosync: [TOTEM ] Totem is unable to form a cluster because of an operating system or network fault. The most common cause of this message is that the local firewall is configured improperly.

multicast also does not work between updated nodes.
