tag-switching on 6500 interface vlan

Unanswered Question
May 15th, 2007

Can I use the "tag-switching" command under interface vlan?

My PE is also a CE. The PE is a 6500 connecting to multiple 3750 stacks using multiple vlans. Should I use the "tag-switching" command under each interface vlan, or under the trunk ports connecting to the 3750 stacks?


I have this problem too.

I can not understand your case 100%, how is you device acting as PE and CE in the same time!! How! Why!

If you are in seperation issue you can use VRF-Lite.

more details about you case will be good.

Regardless I?m advanced Engineer or NOT, I believe it?s not your business, you MUST be grateful for anybody waste at least 30 seconds trying to help you

You have to be advanced engineer to be able to post advanced questions that meant for advanced engineers, (CE/PE).

Also if you are advanced engineer why did you come and post questions, but really I?m sorry to waste my time to replay on a post for someone doesn?t appreciate anything ,BTW the forum opens for all professionals and unprofessional users, I don?t care I hop you find someone help you.

I hope you are doing a CsC scenario where your PE is a CE and PE at the same time.

Whatever the case, you will have to enable label switching on the Vlan Interface, and not the trunk, as to enable MPLS on an interface it should have a valid IP configured on it. And hence you may not be able to use the label0-switching on the trunk.
