[nsp] Holy crap!

[Christopher J. Wolff]

Stacy,

IIRC, there was a BGP setting that holds the session in limbo (bgp
dampening?) Having to failover and wait for the sessions to reload will
definitely make the phone ring.  It's probably because the failover
MSFC2 does not have a current route table?

I have also seen this with the MSFC2s in failover.  I run single router 
mode and when a failover is forced, it takes a quite a few seconds for 
the FlexWANs to reinitialize.  This can be seen through the logging from

the switch as well.

I recently updated to 12.1(13)E9.  When I upgraded, the config for two 
OC3's was lost, but my DS3 configs remained.  I have a one of each on 
each of two blades.  That was very odd I thought.  Anyone see that one 
before?

Looking at the config showed the interfaces, but they were shutdown and 
all IP/settings were lost.  Again the DS3's were just fine.

BTW when you failover and the FlewWANs reinitialize, it does kill BGP 
and all sessions need to restart as well from what I have seen.  Kind of

a pisser for wanting stateful failovers....
