RE: OT Dynamips question

I'm guessing that I should be shooting for about 18 to 20 routers per
machine.

Hi Patrick,

If the software can handle such load (I've never tried more than 20-25)
you can probably get away with a quad core CPU; configure the best
idlePC and split them up across your cores using the "affinity" feature
of Windows (or Unix). Using a 2.6Ghz Quad; each core should be able to
handle 10 routers.

You can buy such machine for less than $300 off ebay but if double your
budget you will get a nice safety margin as well.

HTH

PS. Try to choose the minimum boxes which are able to do the job; for
instance if you don't have to run 7200 with 256MB mem, go for a 2691
(does support MPLS VPN)

I'm looking at 50 routers.

Not sure what you mean by 'very large'...I have a quad core server
running with 8 gigs of ram using gentoo linux and it runs 12-15 routers
just fine plus vmware and being used as a file server....

Hey guys I'm looking at putting together a very large dynamips setup. I
wanted to see what the maximum number of routers people have tried to
lab up that included bgp and other routing protocols running. I'm
pretty sure I'm going to have to put my lab together on at least three
servers.
