Bizzareness and Oddity with IOS
Have a Cisco 7206 (not the newer VXR model, the older one) and attempted
last night to upgrade IOS on it from 11.2(3) to 12.0(7)T. Seemed to run
okay (nothing on boot jumped out and said "broken") and pinged various
bits of the network, with no problems. Left and went home :)
Got to work this morning to discover "Internet broken". (Eventually)
noticed that the 7206 had dropped two static routes, one of which was
the default route. Hmmm.. Add them back, and a few minutes later they
disappear again. Hmmmm..
Perhaps it's something odd comming from the BGP sessions with the WIX
route server? Drop BGP, it still forgets the static routes after a few
minutes. At this point we decided to back out of the IOS upgrade, and
rebooted with 11.2(3), which has been running fine since.
We do have a 3640 with the same feature set/revision, and it doesn't
exhibit this problem. Suggestions? Give up on 12.0(7)T and pick a later
release? Give up on the 12.0 tree altogether? Give up on IOS and Cisco
altogether? :))

As far as I have been able to discerne, the only "working" version of IOS 12 seems to be 12.0.10(S). Love it or leave it, at least there aint no memory leaks (touch wood). Cheers.

This sounds like a familiar site!
Cisco has sent me the following regarding the most stable release for the
7200:...
Hi Guys,
Based on your description of required features ie BGP on a firewall
feature set, you will need the following:
c7200-ios-mz.12.0-4.T (32/16) <<...>> S72CH-12.0.4T or S72CH-12.0.4T=,
which is IP/Firewall.
Basically, you could have any of the images for BGP/4 support however,
to get Firewall, the image name must include FW (firewall).
Please let me know if I can help with anything else.
Regards,
Andrew Hall

Hmmm.. very odd, 12.0(4)T with IP/FW leaked memory like there was no
tomorrow on our 3640 :) 12.0(7)T with the same features doesn't leak
memory (that I've noticed) and doesn't drop static routes either..
Although they are different hardware platforms, so perhaps that'll make
the difference. I will obtain said image and try that :)
