EIGRP with RTO 5000

TRENT WAITE
Level 1
Level 1

I have two nearly identical 881 routers (15.4(1r)T1) running EIGRP that I am trying to mesh with an ASA5500X v9.8. Router 1 works, router 2 does not. 

R1 (working) R2 (non-working) ASA5500
router eigrp 1
network 1.1.1.0 0.0.0.255
network 10.63.5.0 0.0.0.7
neighbor 10.63.5.1 Tunnel1
neighbor 1.1.1.100 FastEthernet4
neighbor 1.1.1.122 FastEthernet4
eigrp router-id 1.1.1.119
no eigrp log-neighbor-changes

router eigrp 1
network 1.1.1.0 0.0.0.255
network 10.62.5.0 0.0.0.7
neighbor 10.62.5.1 Tunnel1
neighbor 1.1.1.100 FastEthernet4
neighbor 1.1.1.122 FastEthernet4
eigrp router-id 1.1.1.118
no eigrp log-neighbor-changes

router eigrp 1
distribute-list eigrp in
no eigrp log-neighbor-changes
neighbor 1.1.1.100 interface outside
neighbor 1.1.1.118 interface outside
neighbor 1.1.1.119 interface outside
network 1.1.1.0 255.255.255.0
network 5.5.5.0 255.255.255.224
network 6.6.6.0 255.255.255.0

 

R2 will show as neighbors 1.1.1.100 (ASA#1) and 1.1.1.122 (ASA#2), but the RTO is 5000. I have tried removing EIGRP from R1, tried different AS #, no matter what I get is RTO 5000. 

Debug eigrp transmit shows;

Aug 16 11:44:02: Building unicast STARTUP packet for 10.1.1.122, serno 0-0 for tid 0
Aug 16 11:44:02: No items in range

So far I have been unable to find anything regarding "No items in range" 

 

Both R1 and R2 connect to the same switch the ASA is connected to, and counters R2's interface do not show any errors. I cant see where this could be a "connection" issue, especially since R1 has no issue. I believe this has to be a configuration issue. But I am unaware of where to look next.

Hello,

 

do you have one or two ASAs ? Post a schematic drawing showing what is connected to what. Keep in mind that EIGRP uses split horizon by default...

Also remove all neighbor commands from all devices, and just announce the iinterfaces...

Removing the neighbors was the answer, R2 is now showing up as a peer on the ASA. I do have a separate issue with it still having RTO of 5000 and is not re-distributing the route I need forwarded to the ASA. However the GRE tunnel will soon be going to a different router dedicated for this purpose, so I am not going to worry about this for now (it is good for learning purposes for now).

 

Thank you for providing a quick and easy solution

Hello,
