Title: Cisco 3640 grunty enough for full-BGP routing?

A 3640 with 128MB is more than enough.  A full route table takes up less than 20MB. Here my BGP summary and memory utilization.  Do the math...   #sho ip bgp sum BGP router identifier xxx.xxx.xxx.xxx, local AS number xxxxx BGP table version is 40912247, main routing table version 40912247 87050 network entries and 87129 paths using 11580494 bytes of memory 26531 BGP path attribute entries using 1380600 bytes of memory 11347 BGP AS-PATH entries using 286472 bytes of memory 0 BGP route-map cache entries using 0 bytes of memory 50 BGP filter-list cache entries using 600 bytes of memory Dampening enabled. 134 history paths, 139 dampened paths BGP activity 4499686/10692951 prefixes, 14624309/14537180 paths   #sho proc mem Total: 111299776, Used: 70252848, Free: 41046928 ""John Kaberna"" <[EMAIL PROTECTED]> wrote in message 002501c021ad$3c622e20$[EMAIL PROTECTED]">news:002501c021ad$3c622e20$[EMAIL PROTECTED]... The BGP routing table itself takes up less than 20MB of memory last time I checked (only a couple months ago).  I don't have access to a router running full BGP routes right this moment but someone should verify this.  I am fairly certain it is less than 20.  So, you can run it just fine on a 3640 with 128mb.  I completely disagree with this "experienced" CCIE.  However, his routers may have several other services running on them that use a lot of memory.  A 3640 with 128mb used simply as an Internet router running BGP will have no trouble now or in the near future.  Does anyone have a 3640 w/BGP that could provide some current stats?   John ----- Original Message ----- From: Guyler, Rik [EESUS] To: Jeff Wang ; Cisco Groupstudy (E-mail) Sent: Monday, September 18, 2000 9:13 AM Subject: RE: Cisco 3640 grunty enough for full-BGP routing? A CCIE, experienced in the service provider market, just recently told me that a 3640 *might* be OK at first, but it would really be a strain to keep the entire routing table.  His reasoning is that 128MB RAM barely covers the requirements and will allow no room for growth.  He went on to say that if you can, use 256MB, 512MB, etc. as new routes that are added in the future will drive your memory requirements beyond 128MB.   Rik Guyler -----Original Message----- From: Jeff Wang [mailto:[EMAIL PROTECTED]] Sent: Monday, September 18, 2000 12:18 AM To: [EMAIL PROTECTED] Subject: Cisco 3640 grunty enough for full-BGP routing? Hi all, Just a quick question regarding 3640 with 128MB DRAM.  Will it be grunty enough to run full-BGP, talking to two different providers and getting full routes, with one E1 2Mbps WAN link to each provider?  What's your minimum configuration from experience?
