I like to use a 7206 with 256Mb memory as a minimum although I do have
numerous 3640s doing full routes with 128 Mb memory. I like to use the 7206
because I can use some additional security measures without maxing out the
CPU. I use numerous access lists and bgp prefix lists to increase security.
I find that on the 3640s my CPU usage is already about 50%.

Subject: Re: How Big a router for Full BGP routes?
This is being discussed more and more often. The organization I work for is
just about to do out part to make the Internet Routing Table 1 route larger.
We have had a legacy Class C block for years, but never used it. Over the
next couple weeks I'll be setting it up to advertise across a couple
different ISPs.
Like someone further down in the thread stated as well, I'm only planning to
receive the routes that originate from the AS's that I peer with. For all
other traffic, I'll just use a default route...
