I would like to achieve load balancing (using variance and CEF) over 4 EIGRP routers interconnected in squares by two connection each, one Fast Interface (used as a WAN) and the other ATM PVC as proper WAN. Two routers (in the Data center) connect a one LAN segment and the remotes connect different IP segments (they are stub) on their Ethernet port.
Now, my candidate routes already have the right routes on the topology table... But, before to apply the variance command I would like to make sure, that the neighbor will not send back the incoming traffic for same interface that they have in common. Let?s say it is making like a ?pseudo loop?. I read about split-horizon but I am not so clear to me... So, it seems that I need some help.
