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

[James Yunkin]

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!
