i have a Level 3 backbone with One cisco 3745 and a lot of 1721 actually connected by a MPLS VPN.

I want add a Layer 2 transport point to multipoint. Anyone know if it's possible and what is the best choice in configuration without lose IP Address on cisco 1721 for internet access ?

    Accepted Solution

    L2 transport is typically done within the carrier's mpls cloud. This is how they separate your traffic from other customers.
    What exactly are  you wanting to do?
    LVL 32

    Assisted Solution


    Right, I agree with lrmoore. Ask your MPLS provider for Layer 2 connectivity between the desired endpoints. This typically configured on the providers PE using L2TPV3 or AToM.

    You can't just delete Level 3 because you need a carrier.
    If you read the whitepaper in the link above you will see the references to Provider edge equipment. That's L3. You can't do it alone.
