L2 pseudowire interworking ATM-Ethernet

Unanswered Question
Jan 23rd, 2009

Hello.

I am trying to configure a L2 pseudowire L2 that ejecutes inteworking in the following topology

the pswudowire is not active buy I don't find anything wrong in the configuration. I Have tried with in and ethernet interworking but the pseudowire alway remais as showed below

Hello

Did you enabled directed ldp session between two edge Pe of the MPLS network which is a necessity for your l2 pseudowire to come up in mpls.

Hello Pedro,

I notice that second PE doesn't see up the ATM PE

Signaling protocol: LDP, peer unknown

Targeted Hello: 10.19.1.4(LDP Id) -> 10.19.1.16

while the first PE says:

that it sees the peer up.

So verify ip routing for loopback interfaces the ip addresses have to be published in your IGP routing protocol and be also advertised by LDP to create external MPLS label (end-to-end LSP with destination remote loopback ip address).

Another possible issue is the ATM/FR interworking part, the FR DTE says its FR subif is down down and the pvc is inactive.

Verify if Alcatel network is correctly configured to create a PVC with that DLCI on the FR side and that arrives on the ATM PE node.

Hope to help

Giuseppe
