[c-nsp] problem with EIGRP

[Nikolay Abromov]

Hi There, 


I've got a problem with EIGRP, I run eigrp session over tunnel and the
session
goes down in about 1min. below there are some logs from both routers


Router A (7206 VXR-NPE-G1,IOS version 12.3.12) 

%DUAL-5-NBRCHANGE: IP-EIGRP(0) 1111: Neighbor 1.1.1.1 (Tunnel3) is down:
retry limit exceeded
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 1111: Neighbor 1.1.1.1 (Tunnel3)
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 1111: Neighbor 1.1.1.1 (Tunnel3) is down:
retry limit exceeded
%DUAL-5-NBRCHANGE: IP-EIGRP(0) 1111: Neighbor 1.1.1.1 (Tunnel3) is up:
new adjacency


Router B (1750, IOS version 12.1.20)

EIGRP: Received HELLO on Tunnel1 nbr 1.1.1.2
AS 1111, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0 peerQ un/rely 0/0
K-value mismatch

I verified the configurations of both routers and assured there is no
mismatch
of k-values,this is the output of 'show ip protocols" 

router A>
Routing Protocol is "eigrp 1111"
  EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0

router B>
Routing Protocol is "eigrp 1111"
  EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0


I also noticed that they'r 13 update messages which are constantly
pending
in the queue.


"show ip eigrp neigh"

Has anyone experienced similar problem?
