Our network is divided into two parts (each part is managed separately). Long ago we decided to merge our routing protocols using OSPF. Our side has seen some issues with OSPF because of its inability to load balance the way we want. For example: we have multiple remote networks that have redundant links to out two main hubs. They are not the same distance away as far as the path is concerned. At many times one of the redundant links will be getting hammered while the other link is barely seeing traffic. We would like to start implementing EIGRP to help solve this issue. We would like run EIGRP over OSPF for the sake of the second half of our network. If we really like EIGRP, we will pull OSPF out completely and just use EIGRP and redistribute into OSPF for the second half of our network. The question is this: what kind of behavior could we expect to see while having two routing protocols running at the same time?
I have this problem too.
