[nsp] OSPF bugs

I'm still seeing a bug in OSPF on my 3640 running
IOS (tm) 3600 Software (C3640-I-M), Version 11.2(13)P1, RELEASE SOFTWARE
(fc1)

What happens is I have a router running gated that exports a few routes
for devices that can't speak OSPF. i.e. it exports a route for some
subnets with some other box as the gateway. This generally works fine for
all my devices...but occasionally (like today) we needed to temporarily
route some subnets to a different box, and the 3640 above received the new
routes but also held onto the old ones, and kept using the old ones.

I restarted gated several times on the system exporting the routes with no
effect, and even shut down gated long enough for the neighbor status to be
lost (the gated box was considered dead) and still the 3640 wouldn't throw
away the routes.

At the time, the 3640 was BDR, and a Lucent PM3 was DR.

I've seen this problem before on 11.2(8) on the 3640, and 11.0(13) on
2501s. I was tempted to use our 3640 smartnet contract today, but I
didn't feel like sitting on hold.
