I am facing a routing problem. Refer to the attached document for network topology.
On the C2811 router (IOS 12.4), I can ping to any local VLAN segments. But I can't ping to remote 10.10.31.x/24., other than .254 host. But on the C1841 router itself, I can ping to 10.10.31.x/24.
On the C1841 router (IOS 12.4), I can ping to 172.26.10.x xecept for .2, .1 and other VLANs. When I do a traceroute (eg to 172.26.10.2), the hop stop at 192.168.10.2.
Any1 know what's goes wrong?
