Hi,
We had a recent change on our network wherein we changed over to MHSRP from plain HSRP and distributed vlans on the Core-Switches on odd-even basis. Ever since the change Multicast receivers on the odd VLANs are experiencing breakages in multicast stream. The following PIM messages are repeatedly logged on the Switches :

It apears that PIM neighborships are not stable. Anyone has a clue on how to proceed with further troubleshooting on this ? The multicast application being used is one for trading. Its called Odin.
