[c-nsp] L2TPv3 vs. VPLS

[Önder Ergün (Probil-İstanbul)]

For those of you who are interested in Layer 2 VPN technologies, there is an excellent book by Cisco Press, Layer 2 VPN Architectures ISBN: 1587051680

Vincent,

If you don't need P2MP and don't have MPLS backbone in place don't even consider VPLS, there are still some major limitations.
I think either L2TPv3 on layer 3 or QinQ on layer 2 would be suitable for you. In the past I used L2TPv3 between 2x10720 to transport 4Gb L2 traffic between 2 IX's, worked just fine, the only issue we've had was MTU when main
STM16 ring went down and L2TP tunnel was rerouted via Ethernet links.

Hope this helps,

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?

Vincent
