用mp-bgp send-label。

support BGP-VPLS.

发帖数: 17771 | 10 right, again the BGP I was mentioning is NOT the BGP for discovring the
neighbors in L2VPN, I was talking about how the ASBR's distribute labels
between AS's. The link I posted was just for clarifying the purpose of send-
label command. My understanding is, send-label is just for exchanging ipv4
and labels with peer without enabling ldp on the ASBR's, it doesn't have to
be inter provider l3vpn right?

you mean targeted ldp signalling? why I remember IOS can do bgp l2vpn now on
7600?

发帖数: 1038 | 13 Mostly for business and political reasons, partly for belief and technical
reasons, :) IOS won't be allowed to support BGP-VPLS. but IOS-XR decided to
go ahead to support it to counter some of the Juniper efforts. :)

发帖数: 1038 | 14 But I think if you want to set up l2vpn, you cannot use the following BGP
method to distribute the labels. The PE-agg-1/2 config you mentioned is for
l2vpn which in IOS you can only use LDP to distribute the label.

发帖数: 17771 | 15 why? the igp label distribution should be the same bah? I made the send-
label method work for inter-as l2vpn, and at the same time, the inter-as
l3vpn works fine too. the ebgp between ASBR's should do the same job

发帖数: 1038 | 18 ah, I think you used the bgp send-label command for pseudowire-switching,
which actually is stitching two pw together. the send-label command is used
to set up a lsp between the two ASBR, isn't it?

发帖数: 1038 | 19 I have some questions. When you tried the l2vpn, did you implement Option A
or Option C? In Option C, how did you distribute the label between PE and
ASBR? LDP? How the end to end LSP was setup?
BTW, Option B is not fully supported in Cisco yet.
