Since these boxes are priced around $3000-$4000 or so and have multiple 
gig ports and loads of 10/100 ports, they make a nice edge/distribution 
box.

Extreme I-chipset stuff talk ISIS, OSPF and BGP just fine and have 128 
megs of memory, and they do L2/L3 at wirespeed (once the flow is set up). 
The L2 is interesting since then you can use it for basically everything 
and not L2 or L3, but both in the same box and on the same links.
