[c-nsp] VPLS to multiple end points

[Michael Hobl]

Hey Shawn,

By definition all VPLS circuits are multipoint, VPWS (aka VLL's, xconnects)
is used for point-to-point designations.

Nuance aside, multipoint is a pretty common deployment strategy for L2VPN
services-- you'll want to look at using L2 VFIs for this.

A good reference point would be here:

Additionally, you can look at using BDI's if you need to provide routing
capabilities to the VPLS.
