Here are a couple things to check:
acl's blocking multicast traffic,
authen config on one side but not the other or
authen not configured consistently on both sides,
inconsistent eigrp timers,
passive interface being used on one side.
inconsistent ip subnet masks.
I might help if we could see your config.
HTH, Tim

Subject: EIGRP problem
Hi,
I have a peculiar problem that I cannot seem to get to the bottom of.
Two routers connected via a serial cable using HDLC
R1---------------------R2
R1 S0 ip address 54.1.1.6
R2 S0 ip address 54.1.1.254
EIGRP has been configured on both interfaces, however the two routers do not
become neighbors.
I have looked at debug ip packet from router 2 and it is sending eigrp
packets and recieving eigpr packets from router 1. Similar results are seen
on router 1.
s=54.1.1.254 (local), d=224.0.0.10 (Serial0), len 60, sending
broad/multicast
00:20:58: IP: s=54.1.1.6 (Serial0), d=224.0.0.10, len 60, rcvd 2
00:21:02: IP: s=54.1.1.254 (local), d=224.0.0.10 (Serial0), len 60, sending
broad/multicast
00:21:03: IP: s=54.1.1.6 (Serial0), d=224.0.0.10, len 60, rcvd 2undebug all
However if I debug eigrp packets I do not see that I am recieving any
packets, only that I am sending them (again similar results seen on router
1)
0:19:57: EIGRP: Sending HELLO on Serial0
00:19:57: AS 100, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0

00:20:15: EIGRP: Sending HELLO on Serial0
If I look at eigrp traffic this confirmed
