Should you have got a non-XL and RSP720 being equal to Sup720 in regards to capacity (that's the 256k max) you'll need to swap RSP to handle a full BGP table. Also pay attention to the combination of RSP and DFC's equipped. A XL-RSP will operate in non-XL-mode as soon as even a single non-XL-DFC is installed in the chassis. regards, Marcus -Ursprüngliche Nachricht- Von: cisco-nsp-boun...@puck.nether.net [mailto:cisco-nsp-boun...@puck.nether.net] Im Auftrag von Raheel Muhammad Gesendet: Donnerstag, 17.

[c-nsp] BGP routing table !!
Hi guys, Might be a basic question but i couldnt find anything, i have cisco 7606 i just had a new peering with our upstream provider, but router rebooted when routes reached 300k, router is not running anything else as well. Any idea? Cisco CISCO7606-S (M8500) processor (revision 1.0) with 851968K/65536K bytes of memory.
