I need help solving an eigrp problem/design problem. I have an eigrp network for redundancy but it is not working the way I need it to. We have 2 CORE routers (1 and 2) at two different locations that connect back to vendors mainframe. We have no control over the CORE routers (none eigrp) or the mainframe. Our routers (A and B) are connect the core routers via Ethernet so they are on the same network. ROUTERA has a 256K frame circuit to ROUTERB and to ROUTERC and is considered a hub router. ROUTERB has 256K frame to both ROUTERA and ROUTERC as well and is considered a hub as well. We have 3 other STUB routers like ROUTERC but to make the drawing simple I'm not listing them. ROUTERA has a static route 10.160.2.0 255.255.255.0 out to CORE1's ethernet (this network is some network on the other side of the core routers). ROUTERB has a same static router to CORE2's ethernet but with a 250 administrative distance. If ROUTERA goes down, everything switches over to ROUTERB and works fine. OK, Here is my problem. If I lose connection to CORE1 from ROUTERA but ROUTERA stays up then the static routes redistributed by eigrp are still valid so the eigrp will not learn a new router to ROUTERB to get to the
10.160.2.0 network. I don't think the vendors who own the CORE will not config eigrp on them.
How can I get around this? Can I setup a loopback and monitor that somehow?
Please help?
