[cisco-voip] IP PIM Passive - Yuck!

[Go0se]

Pim passive keeps the router from sending or receiving pim messages on a
specific interface. I don't know how you have it configured but you do not
want to use ip pim passive on networks with more than one multicast router.
It can result in duplicate traffic or even loops.

Thanks,

Any "successful" experiences with the IP PIM Stub routing feature (ip
pim passive) in the Catalyst IP Base software?

I have gotten Multicast MOH to work with using ip pim passive when the
phone is a hop away from CallManager. I know have a situation where the
phone is 3 hops away (3 layer hops, 5 physical switches) and Multicast
MOH doesn't work.

In UCM, MOH Server configuration, the multicast hop count is 6.
