Enabling Multicast MoH has nothing to do with Multicast discovery of a
GK by a GW.
Multicast is just the transport - enable it for a GW and it will
broadcast (or multicast) out a discovery packet destined for any GK
with a specific Zone name (whatever you configured it as on the GW to
register to).
If the GK is directly connected (such as BR2 GW being directly
connected to HQ router via a Serial Frame Relay link) then you don't
even need to configure Multicast Routing. If it were more than 1 hop
away - multicast routing would have to be configured on all routers in
the path.

If I enable Multicast correctly for MoH, will this allow my gateways
to register to my gatekeepers using multicast? I have never tried
this before but have seen the option in IOS..
Thanks,
