I have a set of 3 Cisco 6509 routers acting as my border routers, each with a BGP session to a different provider. I filter the BGP table coming in from each provider to not send me routes anything smaller than a /24 due to my memory constraints on a SUP720PFC3A. this works great. However, last night, I accidentally took the filter off one of my peers, and it filled up the TCAM Utilization to 100%. I quickly applied the filter, and reset my peering session and the usage then went back down to 40-50%. HOWEVER. I still get messages in syslog about the tcam overflow, and i am having some throughput issues globally, and packet loss on my loopback interfaces. how do i clear the memory problem short of rebooting the chassis?
(i have had this issue before, and rebooting the chassis fixed the issue, but i dont really want to do that) attached is a file with some helpful info. 6509-1.txt
