How to configure VPLS L2VPN Pseudo Wire with MPLS

[Matt_Tinonga]

Hello, I'm needing some help setting up a layer 2 vpn between two X460-24t across a wan. I have all the necessary licensing and feature packs installed. The wan used static routing and is 3 hops away, also the routers in between do not participate in the MPLS. I've started setting up the MPLS and VPLS here's where I'm at...What am I doing wrong?

Hi Matt,

The configuration part looks fine to me for both the peers. Looking at the iproute output, I get an impression that there are other routers in the path. Can you confirm that? Are these devices running MPLS too? We may not have the proper LSPs for every next-hop. may be that is why, the signaling is not active.

if these are third party devices, is it possible to configure the MPLS on these devices and check if that helps!

[Matt_Tinonga]

Hi Prashanth, see my reply in the string below... thanks again for your help.

[Matt_Tinonga]

Hi Prashanth, thank you again... I've stripped the configuration out of MPLS & LDP & OSPF and started over again and used you doc "How to configure VPLS session in Extreme Switches using LDP". I've triple checked the confing and I'll still getting to the same point "Signaling (No transport LSP)".

I did notice when getting to the 2nd part of step (d.) when I rain the command "show mpls ldp peer" it returned nothing on both switches. Not until I added the last command "configure l2vpn vpls vpls-snj-bkd022 add peer 192.168.155.1 core full-mesh" did I get a responce.

OSPF is advertiseing the routes and I can get ping from both end points.

I've copied the configs from both switches in the format of your document link.
Do you have any other ideia? or any test I can run?

Hi Matt,

Good to know that some misconfigs have been sorted out.
If the MPLS peers are operational, there should be a transport LSP for the peer automatically in the VPLS instance. Try re-configuring the L2VPN and check if it helps!

Also, please refer the article below for a sample VPLS configuration.

How to configure VPLS session in Extreme Switches using LDP

Hope this helps!

[Matt_Tinonga]

Thanks Prashanth. I found two issues with my config. I did not have routing between the loopback and a vlan tag was incorrect. I've made the change you recommend and fix the routing issue and vlan tag, I did use diffrent IP for the loppback to better fit into our network.

I do see the end points operational.
