Quick Question, how much memory does the bgp tables actually take. I'm estimating 32 mb in my plan, but I'm worried that's not enough.
Two views: hln-cs1#sh ip bgp summ BGP router identifier 206.127.65.1, local AS number 4043 BGP table version is 132881, main routing table version 132881 112575 network entries and 336143 paths using 24365495 bytes of memory 60397 BGP path attribute entries using 3624720 bytes of memory 53004 BGP AS-PATH entries using 1426946 bytes of memory 0 BGP route-map cache entries using 0 bytes of memory 20536 BGP filter-list cache entries using 246432 bytes of memory Dampening enabled. 96 history paths, 45 dampened paths 111752 received paths for inbound soft reconfiguration BGP activity 112575/456 prefixes, 336319/176 paths, scan interval 15 secs That said: hln-cs1#sh mem Head Total(b) Used(b) Free(b) Lowest(b) Largest(b) Processor 623C83E0 219380768 117525008 101855760 100536360 100521172 I/O F500000 11534336 8157292 3377044 3365952 3352444 By the time you populate the routing table and/or cef, and do a few other things, you probably want at least 256MB. If you are using something else, YMMV - it all depends on how efficient the software is at storing it in memory. - Forrest W.
