[c-nsp] multicast routing to VLAN1?

[Arie Vayner (avayner)]

William,

If you use PIM sparse mode you need to have a valid RP.
If its only this router, then just configure "ip pim rp <ip of
loopback0>"

Another idea is to use PIM SSM, as you use static joins anyway.

Hia,

ip multicast-routing is enabled in global config.
