Is it possible to have multiple vservers listen to the same IP multicast
The reason for this: we have a application in a clustered setup. This means
that multiple instances of this application run, each in a different
verserver. The vservers all have IP adresses in the same subnet. Each
application uses the same multicast address in order to communicate with its
However, it seems that only one vserver at a time is able to receive
multicast, because the multicast traffic (multicast-subnet) can be routed
only to one (and-only-one) virtual-interface at a time. It seems to me that
the problem is the single routing table that is used by all vservers, so
that only one interface at a time can receive multicast.
Can anyone confirm my findings? Or am I missing something?
