I have had an issue with EIGRP on a 1760 connecting to a 3550-24. When the router is rebooted/powered off and back on, EIGRP will not advertise the FA interface network. I have seen this several times before, but have always done a shut/no shut to get the route to get inserted back in the RT. I imagine this is an IOS anomaly as I can't understand why this would be a part of normal EIGRP operation. Has anyone seen this before? Any other fix besides an IOS router/switch upgrade? I don't even think this will be the fix....I've seen this occur on different hardware/software platforms as well.
Here is a defect description very similar to my problem. But this is with like 11.something code!
Description of EIGRP Defect CSCdj58676
This defect was introduced by code changes associated with CSCdj28874. This defect affects redistribution of routes into the EIGRP routing process. The following types of routes may not be correctly redistributed:
A directly connected route
A static route with the next hop set to an interface
A static route with the next hop set to a dynamically learned route
The defect becomes apparent only after a dynamic event, therefore when redistribution is initially configured, EIGRP will reflect correct information in the topology table, however after any sort of dynamic event (such as an interface-changing state) the topology table is no longer valid and routing updates sent will be inaccurate.

Hi,
You are running into CSCdw49187:Connected subnets not in EIGRP topology after reload. The workaround is to configure " event-buffer" command under the interface.

What if this command is not available? I have a 1760 running
c1700-sv8y-mz.122-13.T1.bin
I did look at this bug and it says that this command is not available in subinterfaces. What about the major interface? I don't see it...
interface FastEthernet0/0
no ip address
speed auto
full-duplex
!
interface FastEthernet0/0.10
description DMG_TownSquare_Data

I got some help on this...
The command is a hidden command and does not show up when you do a router(config-if)#?
Just type in event-bufffer
