Arista has a version of their switches that can handle a full table.
I think what the OP is asking about though is something like openflow though.
Some have played around with using it to modify the switches routing table
based on flows that exist. The same theory applies in regard to the

It's really hard to talk about pricing,
I'm going to be keeping a close eye on this:

In my setup, I use an BIRD instance to combine multiple internet full
tables, i use some filter to generate some override route to send to my L3
switch to do routing. The L3 switch is configured with the default route
to the main transit provider , if BIRD is down, the route would be

Hello,
A while back there was a discussion on how to do optimized (dynamic) BGP
routing on a L3 switch which is only capable of handing a subset of BGP Routing
table.
Someone has pointed out that there was a project to do just that, and had
posted a link to a presentation on a European operato
