Hi, There are multiple ways you can solve that problem. We do the following:
1. Each region has its own ibgp cluster with 2 route reflectors (usually the P nodes, since they seem to have abundance of CPU power and not much to do with it). 2. All route reflectors (across regions) are fully meshed. We thought a bit about creating two 'super' route servers, but then then number of adjecencies is not that big ( we only have a few regions ). Regarding internet traffic - we keep the Internet in a VPN, all PEs that host that VPN are fully meshed and advertise only a default to the common route reflectors (in their corresponding regions). Each internet PE uses different RD, so there are multiple default routes present in the regions. kind regards Pshem 2009/9/12 Serge Vautour <sergevaut...@yahoo.ca>: > Hello, > > We're in the process of planning for an MPLS network that will use BGP for > signaling between PEs.
