How do you read BGP memory usage stats? I'm a little confused as to how to
account for the amount of ram listed in the 'holding' column of the 'sh proc
mem' command.
E.g., we receive full feeds from both of our two providers. 'sh proc mem'
lists the 'BGP Router' process as using around 66,000,000 bytes.
If I add up all the big ticket items from the 'sh ip bgp summary' and 'sh ip
route summary' output, it doesn't come very close to the 'sh proc mem'
figure. And, I'm not even sure these items are all counted under the 'bgp
router' process anyway.
E.g.,
network entries in bgp table (26,801,632)
path attrib entries in bgp table (8,881,156)
routes from bgp (19,765,356)
routes from bgp overhead (5,620,216)
Total: 59,068,360
Any elucidation would be *greatly* appreciated.
