[c-nsp] NPE-G1 with 12.2(25)S reload

Mon Feb 21 18:13:42 EST 2005

Hi,

We're in 2 minds at the moment about moving to 12.2(25)S from 
12.2(18)S. A solid 12.2(18) would be fine but 12.2(18)S7 is still open 
to the BGP DOS problem outlined in 
(http://www.cisco.com/warp/public/707/cisco-sa-20050126-bgp.shtml).  
Clayton Kossmeyer @Cisco mentioned a while back that a 12.2(18)S 
rebuild with the BGP DOS bug fix would be made available at some time 
but there's no sign of it nor a release date anywhere I've looked.  So 
the option is either 12.2(18)S with BGP DOS problems or 12.2(25)S with 
CEF interface problems.  I guess we have to pick the lesser of the two 
evils :)
