[cisco-voip] weighted EIGRP routes

[Lelio Fulgenzi]

Any pointers on how to tell a downstream EIGRP neighbour to weigh one route better than another? Do I put the weight on the downstream neighbour to say EIGRP routes coming in on one interface should be weighted more heavily? Or on the upstream router to push down the weights? 

Basically, what I have is this: 



+-----------------------+ 
V V 
3945 -> switch -> VG224 <- switch <- 3945, where switch = SM-ESx-16 

(view with fixed font ) 


Two 3945s with service module ethernet switches which connects to the two VG224 ports. All routing is done on the router and the switch provides layer two connectivity. A port channel group between the two switches allow the routers to communicate HSRP keepalives. The VG224 is an EIGRP stub, and the two upstream routers send out only default routes to the VG224 (that's all I want). 

Everything is working great. Except for the fact that the two upstream routers are equal weight. This means that when the VG224 is talking to the active HSRP address, it's going back and forth. Since the layer two link is up between the routers, it still works, but not ideal. Bad things happen if the link between the routers goes down - split brain! 

Any pointers ?
