i inherited a large frame-relay hub and spoke network with multiple hubs and using only static routing. there are about 10 hubs, and each remote router is connected to one of these hubs, plus a backup hub (the same for every router). we would like to implement a dynamic routing protocol, and i have experience with OSPF and EIGRP. we've decided on EIGRP, but here's the issue and hence my question: the WAN addresses *within* each hub are unique, but there is overlap from one hub to another. for instance, 10.1.1.1 is a WAN interface on Hub1, Hub2, Hub3, etc. Is this a problem for EIGRP? We don't really care about learning the WAN routes, just the loopbacks on the remote routers and some static routes, both of which *are* unique, unlike the WAN addresses.
i hope i made this clear. i understand the IP overlap is not ideal, but getting those changed is an even bigger project than implementing a routing protocol, so if i can avoid it, i will. i believe EIGRP should work, but i know
OSPF won't, because it won't be able to build an accurate picture of the network with all that overlap.
thanks for your time!
