RE: Merge 2 MPLS Network

Thanks, I'm a big fan of INE too ;)

With your diagram, yeah that works fine. Just remember that if this router or
one of its circuits goes down then you're SoL with connectivity between A & B.
Since you're using BGP you may consider adding another router for redundancy,
as the policy control is a lot easier than using IGP.

Thanks Brian. I am a big fan of INE and heard lot about you.

Attached is the quick diagram. The brainstorming plan is that one of the site
will act as an NNI and as BGP is running on the NNI router, the routes will be
learned via BGP which will make the routing decision as where to send the
packets to.

> Did you already ask the providers if they'll run Inter-AS MPLS for you? If
they won't peer, and it's private L3VPN then there's not much you can do other
than multi-home a site both to A and B and redistribute the routes between
them. All inter-provider traffic is going to route through the multi-homed
site though, which will likely be your bottleneck and could be a single point
of failure. What's the current routing design look like?

> We currently have an MPLS network provided from vendor A and we are moving
to an MPLS network provided by vendor B.
> For next 3 months till all other sites get FOC dates we have to utilize MPLS
network provided from vendor A. The only way around is to merge 2 networks and
start routing traffic on MPLS network provided by vendor B, till all sites
eventually are on vendor's B network.
