This is a known issue. See CSCdp26660.
A 2500 router running an IP or above feature set image may restart if
the 'neighbor x.x.x.x default-originate' command is configured for an
established bgp peer.

Subject: ios caveats?????
practicing policy based routing with bgp, when it comes to injecting
default route to the remote peer at the remote AS, the router keeps
reloading as soon as i entered the command "neighbor ip-add
default-originate".
is my router having problem or is one of the Cisco IOS caveates?
the router output is shown below, as you can see it a 2500 .
and after reloading the the ios sh ver reveals the following message to
me .
<r1 uptime is 3 minutes
System returned to ROM by error - Illegal Instruction, PC 0x0>
pls can someone shade some light to this problem and its possible
remedy.
TIA
Hashiru
