[cisco-voip] Multicast issue

[Scott Voll]

I don't even pretend to think I really know multicast, so if this is a
simple question am sorry ahead of time.

is multicast routing directional?  Can you setup multicast to only route in
one direction?

I have ip mulitcast-routing on each device and ip pim sparse-dense-mode on
each interface.

Multicast is going from main site to remote just fine, but I have a device
at the remote site that needs to multicast back to the central site and I
need to know how I go about routing back?

I do have a RP at the Central site manually configured.

Thanks

Scott
