Hi,
I'm trying to run EIGRP between two 3662 conected using an DS3 link terminated over NM-1A-T3 modules on both routers. The DS3 circuit is upand I'mable to ping/telnet between the routers, but EIGR neighbour relations does not formbetween the routers.
The configuration is pretty simple and staright forward and using a similar configuration i've made the routers talk through EIGRP across a T1 link.
Any ides why this is happening..the EIGRP config on both routers is as follows.
Router -A
router EIGRP 100
network 10.10.20.32 0.0.0.15
no auto-summary
no eigrp log-neighbor-changes
Router-B
router EIGRP 100
network 10.10.20.32 0.0.0.15
192.168.18.0 0.0.0.255
no auto-summary
no eigrp log-neighbor-changes
192.168.18.0/24 is the LAN subnet of router-B
ANy idea why this is happening??
Thanks and Regards,
jimmy.

check if anything configured on the interfaces that might stop eigrp from working

I also have the following configuration but am very new to EIGRP so can't swear that it's necessary:
router eigrp 100
network 63.166.58.0 0.0.0.255
neighbor 208.247.138.253 FastEthernet0/0
neighbor 208.247.138.194 ATM3/0.23 (to another circuit)
no auto-summary
eigrp log-neighbor-changes
Hope this doesn't add confusion!

First, check show ip eigrp interface to see if eigrp is picking the interfaces up up correctly. Next, ping 224.0.0.10 to see if you get a response from the other end of the t3 link--if not, multicast between the two routers isn't working correctly. Finally, if it is working, then you might have to go into eigrp packet debugging to see what packets you are getting across the link, and figure out what's going on. debug ip eigrp neighbor might help as well....
