I
don't know the nuances involved, but he stated that the Internet routing table a
year ago was over 70,000 routes and is probably closer to 90,000 routes
right now. Maybe you did not see the complete table when you saw
20MB? I don't know... Like I said, however, he is a 3xxx CCIE and a
Cisco SE, so I find it hard to refute his word. Not that I'm saying you
are wrong, just that I find him to be extremely credible.

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?

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.

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?
TIA,
Jeff Wang
