A postscript to the router allergic to bgp -
This was a 2513 router on an online rental rack. I found that if all
interfaces were down and I enabled bgp first and followed that by
bringing up the interfaces - bgp would function fine. But if even one
interface were up and I entered the router bgp x command, the router
would reload immediately.

Larry,
There are some notorious "features" in the IOS and BGP. One particular
one
that is similar is that the router will reboot when advertising a
default
route in BGP. I did a quick search on CCO in the bug list and there are
67
bugs with the words BGP and reload in it. Take a look there, or provide
some
more info as to the cause of the reload. If you have a show vers, or
show
context we may be able to gain more info on why this occurred.
Cheers,

Has anybody ever encountered anything like this? I was renting use of
on an online rack. When entering attempting to enable bgp on one a the
routers on the rack, a 2513, each time I entered the words "router bgp
3" in global config mode, the router would spontaneously start to reload
within about 20 seconds. After several tries, I pasted in "router bgp 3"
and its subcommands from a text file and quickly did a copy run start
before it had a chance to reload. Needless to say, as I should have
anticipated, the router went into a reload loop, never completing the
reload but starting all over again each time it encountered the bgp
command in the startup config. I contacted someone at the online lab who
was able to erase the startup config so I could access it again.
I went then went back into the same router and typed in a brand new
config and - you guessed it - when I tried to enable bgp, the router
went into reload. Has anyone else ever had this experience?
