[cisco-bba] vpdn multihop question

[Tassos Chatzithomaoglou]

We have a Juniper ERX1400 used as a LAC (PPPoX termination) and 3 7200s used as LNS (L2TP 
termination).
We have defined sgbp and vpdn multihop on all the 7200s and we want to enable Multichassis 
Multilink between all 3 of them. Vpdn is working fine between all of them and multilink 
too as long as the multilink channels end at the same LNS.

Do we need to define something like "vpdn multihop" or "sgbp" on the Juniper (LAC) too?
