[isp-bgp] Re: What small switch/router for full bgp routing table

[sjk <sjk@...>]

We have tried to run a full table on Summit 1i's before -- with little
success -- you can get it to work, but it's painful and forget about
setting communities. . . . If you want to go the Extreme route, look at a
5i with 256MB of memory -- FYI we have also found the Extremes to be very
susptible DDoS problems due to the way they slow path the first packet to
build the ipfdb -- take a look at some of the postings on NANOG about
Extremes during the slammer outbreak.

If you are going to have only one large peer you could take a very limited
table or simply a default route -- this would eliminate the memory
problems with taking 140K+ prefixes.

Hope this helps -- sjk
