I've deployed a 7280SR in that role. Needs the FLX model/license, and a
special TCAM optimization command to install all the routes in hardware.
Right now, just pulling a single v4 feed, expanding to a second soon; no v6
yet. Overall, no major issues with it, but Arista seems to be pretty
close-lipped about the secret sauce in Flexroute that lets it scale over 1M=
.
