Hi, I'm having my bird6 nearly up and running, and just stumbled across the following minor crash. I have a filter defined like this: filter bgp_in_AS1853x104 prefix set allnet; { if ! defined (bgp_med) then bgp_med = 0; if ! (avoid_martians()) then reject; if ! (bgp_path ~ [= 1853 * =]) then reject; if ! (net ~ allnet) then { bgp_community.add((1121,1)); } accept; } You see that I compare allnet to the current net, but allnet isn't set anywhere (due to my forgetfulness). Having this filter in place crashes bird upon the first received route. This is of course rather a human error, and I just wanted to tell the Ondrej's in case they want to fix this bug. I personally don't care if they do, I guess there are more ways of a broken configuration to break bird :) Wolfgang, all excited about his working bird6. -- www.vix.at | www.aco.net wh@univie.ac.at | WH844-RIPE Vienna University Computer Center
