EIGRP Route Advertising/disappearing

[manny.richardson]

I have a strange problem. I have a 7513 that has one static default route. This route is being redistributed into EIGRP.

The 7513 advertises this route along with the native EIGRP routes to 60 remote sites. The remote site router are 3640s. All configs are the same. All location recieves the redistributed default route, except 2 remotes sites. They received it previously, but stopped two weeks ago. One stopped today. They still receive all native EIGRP routes. I have put static default routes on the two router temporarily.

The 3640s are running 12.2(2)XT IOS. The 7513 is running 12.1(3a)E4 IOS.

Have anyone seen this problem and resolved it. Will this gradually happen to the other remote sites. What is causing this?

Did you clear the routing table or reboot the routers and see if this brought it back? If so then it might be a code issue.

I did clear the routing table. No Change. I cannot reboot the router, it is in production and must operate 24/7.

Hello,

how exactly are you redistributing the default route ? Are you using a distribute list ? I am just asking because there are numerous bugs related to EIGRP in version 12.2, one of them being a failure to add redistributed static routes. Can you post the relevant EIGRP configurations from the 7513 and one of the 3640 routers showing the symptom ?

Regards,

Georg

Most of the other 3640s are running the same IOS code as the two that are affected. The rest are currenlty not experiencing the same problem. The EIGRP config for the 3640 is as follows:

interface FastEthernet0/0

ip address 10.240.56.1 255.255.0.0

no ip directed-broadcast

The Config for the 7513 is below:
