[LinuxUsers] Researching Vyatta for routing

[Dino K]

I read that article and it basically compared it to a cisco 2800 series
router, which is usually used for small scale, 10/100 or T1 sized
implementations, the VIA processor or even an old P4 is more than enough for
routing those types of scenarios, the advantage of the cisco is that you can
tack on some of the VPN stuff without slowing the box down too much.

As far as route table size, a gig of RAM is more than enough to hold the
entire internet routing table at this moment.  512 is enough to hold 1-2
peers with full routes, this is speaking of BGP or OSPF.

In our large scale routing environments we actually use Zebra as route
servers which work perfectly fine for BGP route reflection as long as
they're not pushing traffic, so there's that alternative, you can run
multiple Zebra daemons or a consolidated Zebra daemon to do dynamic area or
even edge/border routing on a powerful enough appliance, or buy a Dell
SC1425 off ebay for 300 bucks and you have a beast of a router, although
power consumption is more on the high side.
