Hello,
I would appreciate any help on this:
I have Cisco 7600 with sup720BXL and 1GB memory.
There are 3 BGP neighbors and from which this router receives full BGP routing table.
I noticed high memory utilization of 90% and can be seen on iutput bellow that BGP router is the process which consumes the most.

I filtered all routes except the deafult on one of peers nad reduced number of received prefixes
from 379466 to 1 but memory consumption didn't changed

questions:
1) I thought that process "BGP router" would have reduced "holding" number after filtering cca 300.000 receiving prefixes.
Or I I am wrong and generaly process "BGP router" doesn't relate to how many prefixes router receives via BGP?
2) should I maybe reset that BGP session in order to free memory allocation or this could be BUG?
Thanks and regards,
A
