How to configure CE for port-based EoMPLS ?

Answered Question
Sep 7th, 2010

Hello!

Here is a scheme:

CE1-----PE1-------PE2----CE2

Assume, that PE1 and PE2 are MPLS-enabled and visible to each other.

CE1, CE2 - are Cisco switches

PE1, PE2 - are 7600 routers

I would like to transport several customers vlans through PE1-PE2 MPLS cloud.

For example, using port-based EoMPLS, typical interface towards CE will look like:

PE1# show run interface f8/48


interface FastEthernet8/48
no ip address
xconnect 75.0.78.1 1 encapsulation mpls
end

What configuration I should use on CE1,2 interfaces towards PE ? Just trunks ?

Thanks in advance.

I have this problem too.

Yes configuring the CE interface as a trunk will allow you to carry the VLANs across the pseudowire. Keep the MTU requirements into consideration.

Thanks!

As I understand the only feature that VPLS could add to this scheme is  multipointing ?

Yes VPLS will provide you with multipoint capability, however, support for QinQ as VPLS AC will need to be verified on the respective PE devices.
