Subject: [c-nsp] Cisco GSR Chokes on BGP

Hi Everyone:

I am curious: is anyone doing BGP, with Full routes, on a GSR? 

I am asking because, I have Transit circuit terminated on a 3-Port GigE Line Card, on a GSR 12008 runing PRP-2. Remote peer is sending FULL BGP routes.  As soon as the BGP session comes up, however, the line card crashes/resets. Setting the maximum-prefix BGP parameter to a really low level makes no difference.  The LC is configured with the maximum possible MEM available for that device, and this is the only BGP session on the entire box.


Here is the crashing error I get:
