We have two L3 distribution switches (SA26-LAN-R1 and SA26-LAN-R2) that connects to two 7206vxr (SA26-MAN-R1 and SA26-MAN-R2). From the two routers, I can trace to any destination prefix without problems. From SA26-LAN-R2, I can trace to any destiniation prefix without problems. But on SA26-LAN-R1, when I trace to the same destination prefix the packets just loops around a couple of times, then sends it off. On SA26-LAN-R2, if I run the "show ip route 10.4.249.254" it shows one route. But if I run the same command on SA26-LAN-R1 it shows four different routes.
Attached is a diagram of the network, SA26-LAN-R1 config, sample show IP route to 10.4.249.254, and outputs trace. Any assistance on why there's a routing loop would be greatly appreciated.
