can I use xconnect session between two routers that have interfaces in different VLANs. On one side it is vlan 154 and on the other xconnect is terminated on interface that is in vlan 144?

Dragan,
I quickly checked with the Feature Navigator and it appears that VLAN ID Rewrite feature is supported only in 12.4T.

Are you sure? Looks like it does not work

Hi,
I agree with hritter.
It works in the same way as if you connected a cable between the two VLANs, if that's what you really want to do?
Please post your xconnect config for both sides. Is it AToM or L2TPv3?

router a
interface GigabitEthernet0/0.55
encapsulation dot1Q 155
xconnect 5.5.5.5 55 pw-class class
!
router b
interface GigabitEthernet0/0.55
encapsulation dot1Q 55
xconnect 4.4.4.4 55 pw-class class
!
so if I have same vlan on both sides, then it is ok, but if I change vlan on one side, then it does not work

Dragan,
What platform is this?
Regards

7200
03-10-2009 06:11 AM
Dragan,
Do you use a 7200 at both end? The 7200 platform does support vlan rewrite automatically. There is no need for special configuration. How did you test that it does or does not work? When you changed the vlan on the 7200 did you also changed it on the CE?
Can you post a "show mpls l2 vc detail"
Regards

yes and yes I've changed it on all nesessary places. How to configure vlan rewrite? I do not have this mpls command

Dragan,
As I stated in my previous post, there is no command to enable vlan rewrite on the 7200. it is done by default.
Can you please post the output requested and also let us know what level of code you are running on the 7200s.
Regards

i cannot post you an ouput because I do not have command you are talking about. Ios is c7200-ik9o3s-mz.124-12c
