Re: Directing traffic based on BGP community in a mpls vpn

This is exactly what we so in production. We split up our clouds by communities, marking them on their way out. We block other communities on the way in. This way our default route stays in that region. We have multiple Tier1 datacenters in regions that mark their default route and we accept or deny it if a better one exists in the existing table.

Works extremely well. The challenge is that we have 6 MPLS providers due to the countries we operate in.
