[c-nsp] EIGRP bug? Entry in routing table but topology table entry missing

[Dale Shaw]

Hi all,

C1700-K9O3SY7-M 12.3(17b)

I presume this is a bug, but a dig through our beloved Bug Toolkit
didn't turn up anything useful. Has anyone seen this before?

router#sh ip ro 192.168.154.0

router#sh ip eigrp topology 192.168.154.0/26
% IP-EIGRP (AS 500): Route not in topology table

The route in question (192.168.154.0/26) legitimately existed for a
period of time, however I filtered it out and expected it to disappear
from other routers in the network (DMVPN). I had to manually "clear ip
ro 164.97.154.0" to make it go away and once I did, the problem the
existence of this route was causing went away.

It happened on three devices in the same network -- all Cisco 1720s
running IOS 12.3(17b).

I have a workaround, and it's not likely to happen again, but it would
be nice to be able to reference a bug ID because this caused a few
headaches this afternoon.

cheers,
Dale
