I hope someone can help me with this. I think I am over thinking the solution. I am working on implementing BGP on my network with the hope to continue with MPLS. My network is rather large. I am running OSPF with about 50 nodes on the backbone. I have decided to use route reflectors. these 50 nodes will be all in the same AS. Was was going to use clusters to break up the nodes into smaller portions. I am just having problems as to what nodes should I tie together. I was going to peer the neighbors using the loopback addresses. So my question is does it really matter what nodes I tie together as long as they are kind of close together and have an IGp path to each other. I guess Im trying to group them by how they tie together but a good amount of nodes dont have two common nodes they share. Also, is there a rule of thumb as to how many clients per cluster.
