[c-nsp] MBGP for Multicast with VRF-Lite

[Arie Vayner (avayner)]

James,

Why do you need to advertise multicast routes over BGP?

I multicast, usually, you need to advertise the sources (regular
unicast...) to be reachable through the path where multicast is flowing
(to make RPF work).
The multicast state is usually not propagated using BGP, but using PIM
or MSDP...

Hello,
This one has us stumped.
We have a 7600 running VRF-Lite and we want to run multicast in one of
the VRFs. The VRF peers standard eBGP with a Juniper MPLS cloud. I can't
seem to figure out how to exchange multicast routes with the Juniper.
The "address-family ipv4 multicast" command doesn't have a VRF option,
so it ends up putting the peer in global (which obviously is no good).
And the "address-family ipv4 vrf <x>" doesn't have a multicast option.
How can one send multicast routes via BGP on a VRF-Lite router?
Thanks!
