[c-nsp] 12.2(25)S on NPEG1

[Santiago Felipe Perez]

Hi,is there any bug explaining this behaviour or any answer from TAC to
solve this problem?, because Cisco suggest to go to this release 12.2(25)S2
to solve the problem  "Cisco Security Advisory: Cisco IOS Misformed
BGPPacketCauses Reload",when the IOS installed is any release of 12.2S.

Any suggest?

Yep, that happened here on nearly all of our routers, with NPE-G1 and also
with NPE-400.
We only did minor changes to the configuration (removing a subinterface,
removing an area from OSPF and so on), and suddenly all interfaces had "no
ip route-cache" and "no ip route-cache cef" set.
Interesting enough, it doesn't happen all the time: On two routers with
exactly the same configuration, hardware and software versions, we changed
the same things in the config, router1 had "no ip route-cache" set on the
interfaces, router2 not.

The problem with "clear access-list counter" happened here, too. I'm
currently waiting for Cisco to see that it really is a bug ("Please use
clear access-list instead of clear ip access-list" and "Please update to the
latest release" isn't very good advice when we're already running 12.2(25)S2
and I only left out the "clear access-list" lines in the bug report to
simplify it ...).
