[c-nsp] L2TPv3 vs. VPLS

[Vincent De Keyzer]

Ok,

thanks to Jeff I now have a clearer view of what is VPLS.

I see that VPLS has one advantage over L2TP: it's a point-to-multipoint
technology (which we might not really need). But it also has one drawback:
it requires building a MPLS backbone (which we don't have at the moment).

Is this a correct analysis?

Is anybody on this list using one of these two technologies to offer
Ethernet services over an IP backbone?
