Hi Rolf, Unfortunately the only option is to reset the bgp neighbor after the number of received routes crosses a certain threshold. neighbor x.x.x.x maximum-prefix 10000 75 restart 5 But still better than having the whole box stuck in process switching. adam -----Original Message----- From: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of "Rolf Hanßen" Sent: Monday, February 03, 2014 3:09 PM To: cisco-nsp@puck.nether.net Subject: [c-nsp] Sup720 - FIB full, software switching Hi, today I saw 2x Sup720-3B (default 192K IPv4 routes) that received a full table. After FIB was filled IOS gave a warning that it now may forward in software (and resetted all BGP sessions because of memory issues). I don't have the exact messages. The real problem occured after that. I shut the full table BGP session and cleared the others, the system now had a few routes only again. But it started to drop packets, I saw no pattern, it looked nearly random. I needed to reboot both boxes to resolve that issue. IOS was s72033-advipservicesk9_wan-mz.122-33.SXJ.bin Is there a way to avoid those issues by let it just ignoring routes not matching into the FIB? Is there a command to reset the routing mode/routes back to CEF without reloading the box? kind regards Rolf _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
