I have a bunch of 7280R in a edge-peering role in as2603 network. Works really well and now with the latest additions of subroutemaps and a very optimistic road-map for features i think these style boxes will definitely see more market. Comparing the price of a 7820R 1Tb box with like a Juniper MX with 1Tb worth of ports its not even on the same play-field. I wouldn't count on the 1M routes to last a lifetime but on the other hand its very easy to re-skill the box to something else. If we look at broadcoms road-map there is also new 7280s destined to come out quite soon with the Jericho+ chipset, broadcom promises 20-25% table-increase so we will see what arista, cisco and the others boils it down to when the chip has gotten a box wrapped around it. -- hugge
