R1 is hub, R5 and R6 are spoke routers. router odr with net 0.0.0.0 are
enabled on these three routers.
R5 and R6 runs only odr as it routing protocol. sh ip route on both spoke
routers shows o* 0.0.0.0/0 to R1 -- all right. But they disappear after a
few minutes when checking the routing table by sh ip route again.
Any comments?
Thanks,
Jack
