OSPF Problem

Hi,

I have two routers (Cisco 877 and Cisco 2610XM), both are connected via Ethernet to a Cisco 2950T switch.

The configuration is as follows:

Cisco 877 = R0 int vlan 1 ip address 192.168.0.1 255.255.255.224

router ospf 1 network 192.168.0.0 0.0.0.31 area 0

Cisco 2610XM = R1 int fast0 ip address 172.23.23.1 255.255.255.224

router ospf 1 network 172.23.23.0 0.0.0.31

R0: Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5 R1: Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5

debug ip ospf adj gives me the following output:

R0# Sep 26 13:40:47.215: OSPF: Rcv pkt from 172.23.23.1, Vlan1, area 0.0.0.0 : src not on the same network

R1#

00:40:26: OSPF: Rcv pkt from 192.168.0.1, FastEthernet0/0, area 0.0.0.0 : src not on the same network

Basically the adjacency is not forming and I have no idea why. I have looked over my configuration over and over and can't seem to find the problem. I have also tried searching in Google but haven't had much luck.

If anyone can help out that would be great! Please ask if you require further information.

Thanks
