[c-nsp] 7200vxr-npe400/512mb - how much BGP?

[Skeeve Stevens]

OK,

Just how much BGP should a 7200vxr-NPE400 with 512MB of RAM be able to
handle.

Presently:

Neighbor          V AS  MsgRcvd   MsgSent TblVer     InQ OutQ Up/Down
State/PfxRcd
XXX.XXX.XXX.XXX   4 xxx 1500420   942940  60275730    0    0   2d06h
5634
XXX.XXX.XXX.XXX   4 xxx 15883688  468471  60275748    0    0   00:48:01
249967
XXX.XXX.XXX.XXX   4 xxx 19556635  471877  60275746    0    0   16w5d
248964

So at present, 2 world feeds and a feed from an IX.

BGP table version is 60275748, main routing table version 60275748
251459 network entries using 24391523 bytes of memory
504651 path entries using 18167436 bytes of memory
86074 BGP path attribute entries using 5164680 bytes of memory
77392 BGP AS-PATH entries using 2340778 bytes of memory
525 BGP community entries using 27544 bytes of memory
43080 BGP route-map cache entries using 689280 bytes of memory
0 BGP filter-list cache entries using 0 bytes of memory
BGP using 50781241 total bytes of memory
66 received paths for inbound soft reconfiguration
BGP activity 3758774/3507315 prefixes, 31401381/30896730 paths, scan
interval 60 secs

>From what I can see, "50781241 total bytes of memory" is about 50mb of RAM.

The router currently says "Total: 466497056, Used: 200153224, Free:
266343832"

When should I start worrying about how big the tables are growing and so on?
