I recieved error message from my router about eigrp routing problem that is " Neigbor 192.168.1.249 not on common subnet for FastEthernet2/0 (192.168.9.249 255.255.255.0)
network 192.168.1.0 and 192.168.9.0 is my internal network, it have to send hello packet via serial interface then the source address of hello packet will not internal network but it should use ip address of serial interface.
why the router show this messages ?? and how can i resolve this problem
Are you using secondary IP's on the Fa2/0 interface? Are the interfaces within the same Layer 2 broadcast domain (same VLAN) or is there a hub that also provides connectivity between the 2 EIGRP routers?
Basically, you're seeing EIGRP packets inbound on the router interface Fa2/0 which is on the .9.249 network from the neighbor sourcing the .1.249 address.
1) Verify they are configured correctly (e.g. matching physical IP addresses in the same subnet)
2) Check for bridges, hubs, etc, (This may be by design)
From the design you've presented it doesn't look as though you should be receiving these updates on the FastEthernet interface. You can debug eigrp packet hello - and verify if the router is seeing hello's on that interface.
If the LAN segments don't need to receive EIGRP updates then you can use the passive interface command under the routing protocol.
