Even with IGMP/PIM snooping in VPLS, how do you propose to limit the number 
of PEs in a given VPLS instance. We should keep in mind that a VPLS 
instance constitutes a single broadcast domain among all the PEs in that
VPN.

I am looking at the L2 framework document. And I see bridge modules in PEs
connected by full-mesh PWs (ignoring VPLS forwarders). Then, I am looking at
your web site below

_guide_chapter09186a00801c8b3e.html

and I see some resemblance. Now I am asking the same question to you.
