Hi,
We are trying to run EIGRP over ATM and for some reason the eigrp neighborship wont come up. Please find the interface details and the sho ver from the router. Cisco Feature Navigator says it will support.
Thanks in advance,

Hi:
Why are yo using a multipoint configuration? Can you show us the other end of the EIGP neighborship? Have you thought of implementing a point-to-point configuration?
Thanks

Hello Sundaram,
you are using ATM SVCs.
First of all, is ATM SVC up ?
from router1 can you ping 172.20.254.254 ?
post sh atm svc
Hope to help
Giuseppe

can you also attach the eigrp config for both sides. Are you using the same AS on both sides for EIGRP?

Do not show anything on the running config. But when tried again, it says EIGRP runs on the same AS. What could be wrong here.
Thanks in advance,

can you do a sh ip protocols on both routers?
09-04-2008 04:26 AM
are you saying on router 1 when you did the sh run, nothing came up at all????? & that you had to try a 2nd time to get anything to come up?

Hello Sundaram,
on router-2 you see:
Routing for Networks:
10.0.0.0/16
you need a network command for net 172.16.254.0/24 even if you use the neighbor command.
router eigrp 100
net 172.16.254.0 0.0.0.255
about router-1 check with
sh run | beg router eigrp
if missing add the same network statement here.
Hope to help

Hi,
After sometime now, we started working with this issue now and on two more routers we find the same issue.
We could enable the eigrp and type all the commands but it fails to show up on the show run. We double checked the feature set and it seems to be alright. what could be wrong here.
Please find the IOS Version details.

Hello Subra,
>> you need a network command for net 172.16.254.0/24 even if you use the neighbor command.
You need a network command for the IP subnet that is associated to the ATM link even if you use the neighbor command to avoid to use multicast Hello packets: it is the network command that decides if EIGRP is active on an interface or not.
Hope to help

Subra,
We need to address the fact that you are unable to view the running-configuration before making any changes in any of the routers.
Both routers are running a very old code and I highly suggest doing some research for picking a newer release. There are a lot updates made to IOS in the last 6 years in terms of bugs and features.
With that said, let's try rebooting Router1 during a maintenance window and see if you are able to view the running-configuration once again. It seems the router has ran out of memory or it has hit a bug which has caused to crash some internal services which may be affecting EIGRP.
Please let us know if the reboot has fixed your issue before making any more changes in neighboring routers.
HTH,

Hi,
Thanks for the quick response.
We will have a maintenance window this month. Will do that and get back to you.

Subra
