EIGRP Table problem

i have 2 routers 1-Cisco 1700 with ip address 10.0.0.10/16 connected to 2nd routher Cisco 2851 (10.0.0.9/16)

on the other port of 2851 i have another netwotk 10.1.101.0/24 and on the other port of 1700 i have 172.22.22.0/30

i used eigrp 100 on both of them i used no auto-summary

but i can not see 172.22.22.0 network in 2851 routing table

also i can not see 10.1.101.0 on 1700

i attached both configs for 1700 and 2851

appreciated if somebody can help me

The problem is easy to fix. On the 1700 you have a single network statement under router eigrp 100 which makes the seial interface active in EIGRP but there is no network statement which includes the FastEthernet. If you will add to the configuration under router eigrp:

network 10.1.0.0 0.0.255.255

then the router should become neighbors and exchange routes.

If you want to verify this before you fix it you could do show ip eigrp interface on the 1700 and see that only the serial interface is there. After you add the second network statement then both interfaces should be there.

Also I note that on the 1700 you did show startup-config. This shows what is in the config in NVRAM and can be out of sync with what is actually running the router. It would be better to use the output of show running-config in doing troubleshooting since that does show exactly what is running the router.
