Inter AS MPLS VPN

Haris P · ‎04-20-2009

Dear experts ,

We are planning to interconnect our MPLS with one of the other provider in Europe .

There is no MPLS support between us and the provider and there is no diarect connectivity . I'm planning to establish the MPLS BGP with other provider and sharing some MPLS VPN routes .

What are the best ways to do it ?

In my case can I establish the MBGP connection with my loopack IP ?

Regards

Haris

Hello Haris,

>> There is no MPLS support between us and the provider and there is no diarect connectivity

Without direct connectivity I think you need to use some form of GRE tunneling between you and the other provider.

the GRE tunnel provides you a logical MPLS link between you and the other provider.

Other solutions are possible.

Hope to help

I agree with Guiseppe. You need GRE tunnels but only inter-as option A will be supported:

So you will need one tunnel per vrf.
