crossbow discuss - Feb 2007 - Multicast groups? within crossbow and over IPMP?

We have had an interesting issue with Market Data and Network Interface failures
in the past with ipmp (or even VCS multinicA)..  Multicast groups can not span
multiple interfaces and in our environment when we have a network failure the
interface is failed over however the multicast group does not.  The only way to
recreate the multicast group is to restart the application with the active
network interface.

Do you know if crossbow might be able to handle this?  

I have not discussed this issue in a long time, so not even sure if market data
still has this type of issue?

IPMP does failover multicast memberships transparently as part of the 
failover.
If it does not work seamlessly across the failover, it is a bug.
