Thanks Sergey, That fixed it, it was the use of the port channel that prevented the xconnect from establishing. May look at SRE code next. Andy

Hello, Which IOS version used on c7600s?Potentially the root cause is that Port-chan is your core facing MPLS int.If core-facing is not a bandled int (not a port-chan) than should work just fine in SRD. AFAIK the MPLS core-facing port-channel interface is not supportedwith svi/vfi xconnect configuration before 12.2(33)SRE.The restriction was that you can not have VPLS or SVI EoMPLS VCs ifyou have mpls ip under port-channel interface. The support was added for ES, ES+ in SRE, while implementing feature“H-VPLS with Port-Channel Core Interface”:http://www.cisco.com/en/US/docs/routers ... #wp1458749 This feature is available in 12.2(33)SRE, as shown in the following link:http://www.cisco.com/en/US/docs/routers ... _pref.html So if poosible, consider SRE to test. Thanks,Sergey

There are many constructs available on how to deploy a L2 service. You can have point to point, point to multipoint, or other topologies. You can also create PWs differently. The way you are deploying them I come across when working with 3750ME switches. Otherwise on ES linecards nearly all of the deployments are using LFI or service instances. They are just different way of doing things and achieving functionality that you need (or your services require).

Hi, Just tried your suggestion using the PWCLASS, I had tried this before but not included the status keyword. However, when I look at the output of show mpls l2transport vc 1010 detail I see that there was nothing under the outgoing interface,and no labels. Checking my config, the link between the 2 nodes is a port channel, I had mpls enabled on the channel, but not on the physical ports, so tried this, didn’t make any difference. In the network I also have just built a redundant path via a 3rd node. As part of the debugging work I shut down the port channel.  The xconnect established over the redundant path. This is really odd, as I already had a vrf working across the port-channel, before I built the redundant path, so I thought the MPLS was running ok, now Im not so sure. It now looks that the xconnect won work across a port channel, although Im not aware of any restrictions regarding this. Am doing more work on this. Do I need to include the service instance as well? Im just reading up on this.

Well, if its PW, then enable detailed status messages: pseudowire-class PWCLASS encapsulation mpls status int vl 10xconnect 10.255.255.1 1010 pw PWCLASS  After that, look at the detailed status:show mpls l2transport vc 1010 detailUsually i come into contact with LFI or Service Instance constructs E.g.:(define service instance under ES interface)service instance 1 ethernetencapsulation dot1q 10rewrite ingress tag pop 1 symmetricxconnect IP_ADDRESS 50 pw-class eompls
