[c-nsp] VRF-AWARE MBGP

[Josh Fleishman]

I'm looking for a way to advertise vrf routes via MBGP.  I would expect it
to look something like this:

router bgp AS#
address-family ipv4 vrf NAME multicast

or

address-family ipv4 multicast vrf NAME

But neither of these are valid options. Any suggestions?
