Basic routing on 2901

[Jon Are Endrerud]

Hey everyone

Im a novice when it comes to Cisco routers. Have a 2901 in house now, and trying to get it to route between the two main interfaces. But no luck!

Routing is between the 10.16.108.x and the 32.54.20.x network. The "ip routing" command has been runned.

S*    0.0.0.0/0 [1/0] via 10.16.108.1
      10.0.0.0/8 is variably subnetted, 4 subnets, 3 masks
C        10.0.0.0/23 is directly connected, Vlan1
L        10.0.0.7/32 is directly connected, Vlan1
C        10.16.108.0/22 is directly connected, GigabitEthernet0/0
L        10.16.108.2/32 is directly connected, GigabitEthernet0/0
      32.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        32.54.16.0/20 is directly connected, GigabitEthernet0/1
L        32.54.20.33/32 is directly connected, GigabitEthernet0/1

Attached the whole config as text file.

Everything looks good on this configuration for basic routing. Is your test machine on the 10.16.108.0 network configured to use 10.16.108.2 as its default gateway? Similarly, is the one on the 32.54.20.32 network configured to use 32.54.20.33 as its default gateway? If the test machines don't have a path back to the router's interface, that's going to create a problem.

As mentioned by Jody, config looks okay.  Besides checking host gateways, also insure their network masks conform to the networks defined on the router.

Thanx Jody, of course I have no retur route in the 32.x.x.x network.

That will get you every single time. I'm glad it was an easy fix.
