EIGRP not working

Jul 14, 2009 4 Replies

We brought up a bunch of sites with aATT MPLS and one of them is not working with EIGRP. I'm waiting for a return call from ATT but in the mean time I'd appreviate it if someone would like at these edited config and tell me if tehre is anything in here which would stop EIGRP from working. If it was working, the sh ip route command would return about 50 networks as "D EX".



Thanks for looking.

Gateway of last resort is 192.168.25.7 to network 0.0.0.0



C 192.168.25.0/24 is directly connected, FastEthernet0 S 192.168.26.0/24 [1/0] via 192.168.25.10 10.0.0.0/16 is subnetted, 1 subnets S 10.2.0.0 [1/0] via 192.168.25.10 S* 0.0.0.0/0 [1/0] via 192.168.25.7

Your "network statement" under EIGRP is incorrect. try "network 192.168.25.0"

Hi, the reason it is 192.168.0.0 is because we have many 192.168.x.x subnets, and this is one of many. But I will add that one and see what happens....

Holy cow - you were right!

Thank you so much!

192.x is a class C, meaning auto summary will not pickup 192.168.0.0/16....it only picks up /24. That's why it worked. Or you could have added 192.168.0.0 0.0.255.255.....either way.

Auto summary and the network statement bit me in the tail quite a few times.
