[j-nsp] Junos BNG PPPoE inside a VPLS

[Paul Stewart]

Has anyone configured this up?  I'm looking to implement it (testing at
this point) but confused...:)

It looks like you still need to utilize an LT interface to identify which
PFE is going to do the heavy lifting?  Believe it or not, I've never
actually configured an LT interface before so this is perhaps a silly
question but which interface would I want for this purpose and how much
traffic could it handle?
