RE: Anyone using?

You missed the question. Timothy is interested in finding companies who have
deployed the latest generation of edge devices. These devices specialize in
QoS, VPNs and more intelligent(CPU intensive) features. A GSR is not in the
same classification since this router is meant for the core. Vendors
competing in the edge space are Shasta, Ennovate, Cosine and Unisphere to
name a few.

We were close to getting some for our network, but were unable to get any 
hard facts about people who are using them as "backbone" or "border" 
routers. In the end, we've decided to go with Cisco GSR's.

The flaws we tended to find were with not enough enough memory to hold 
full routing tables, or a limit on the number of route entries. Another 
flaw was mentioned with regard to the route caching - something about 
needing to hold in table of which IP addresses were on which port (usual 
switch behaviour).
