BOOTFLASH: 7200 Software (C7200-BOOT-M), Version 11.1(19)CC1, EARLY
DEPLOYMENT RELEASE SOFTWARE (fc1)

Consider updating your bootflash to be somewhere near currrent
(something from 12.2T would be good, identical to the current version

Good advice.

Presuming you aren't running low on memory (show mem sum) or trying
to
push a ton of packets through it, I'd say this is likely a
cutting-edge-code problem, not a platform problem, and a hardware
upgrade might not do anything to help you. I don't know anyone who
is (admits to?) using 12.2* in production. You say you need MSDP

:slight_smile: We are using 12.2(1) in production. It is stable except... CEF is
wierd, PPP Multilink doesn't work, and there is a small memory leak
with BGP. We NEED to run it for PPPoE support over ATM. It is
realatively well behaved considering it is bleeding edge.

12.1 and 12.2 both have some very significant BGP CPU-race conditions.
We've run in to it many times. It's hardly documented in cisco-land, but
one TAC person I spoke to knew about this.

For us, very recent 12.1E versions have this situation fixed. (12.1.8aE2)

We ran into this in all 12.1 mainline, certain 12.2, and early 12.1E had
it. I think 12.1T had it as well (I am anti-12.1T for other reasons).

CEF seems very good in later 12.1E (but, strangely, I've not had many CEF
problems except on a 6509).

Good advice.

Except, that older 7200's don't have enough flash to do it. Official cisco
opinion is the latest 12.0S.

PPPoE is very well supported and works perfectly in 12.1T (which I hate,
as spoken to above, but since we don't run BGP on DSL aggregation routers,
it's moot). One 7206 here with a lowly NPE-200 is handling well in excess
of hundreds of PPPoE sessions over DS3-ATM.

Heck, we've even a 4700M running 12.1T with many PPPoEoL2TP sessions
running fine.
