[j-nsp] Stiching L2 to L3 on MX480

Hi,

It's mainly scale of things (into hundreds) of Vrf (or access vlans),
routes per vrf and the fact that all of those vrfs will need a BGP session.
Ideally I'd like to be able to run BFD as well for each of those sessions,
but I'm not sure if MX can do it on those virtual interfaces, backup plan
is to run a loop-cable between two ports on the MX.

kind regards
Pshem
