Agree that there should be hints about RD assignment policy (unless it's always per-VRF :)). 

I won't comment on RTs.

l3vpn/vpn-svc/multicast/rp allows specifying RP's IP address.

Should these be added to
sites/attachment/connection/routing-protocols ?

Has an af -- so, should handle both unicast and multicast. No such variable VPN-wide, though. 

Rate of change not captured, afaict.
