Something I always liked on the groupstudy was the fact that unlikelly other
lists there weren't people like. I leave the list for 3 months when I come
back I met a person like you.
Anyway, I was not sure if you have something against me (I doubt it), or
against the company that I work for (possible) or if you just have an
attitude problem (most likelly). I didn't have to read many messages from
the archive to find out that the you definetly have match the 3rd category.
In fact, your post about the CCIE written just confirmed that.
If you look over the archive you'll find out that I've been countributing to
the list for a long time and always treated people with respect.
Said that, let's go back to the original topic. I collected some information
from the routers and hopefully that's going to help us all understand things
a little better.
On the router that is receiveing full routing from 3 different sources +
some minor BGP tables from another source, I have:
routername#sh proc mem

As you can see on this router, the output from sh ip bgp sum shows that the
BGP tables are really only 16Mb large, but the sh proc mem shows that the
BGP process overall uses about 71Mb.
I hope this post helps the rest of the members of the list.

First of all I've never heard of an "as is" or "summarized" version. It's
either full routes or partial routes. Second, you shouldn't say something
if your not prepared to explain what you mean. I have received full routes
from several providers and the table has never taken up more than 20MB. I
have always requested full routes.

Some ISPs offer full routing in two flavors: "as is" or a "summarized"
version (maybe that's the case). Please don't ask any additional details
because that was long long time ago...

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?

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.

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
