Mine don’t do anything fancy; just BGP to a few upstream peers and OSPF/OSPFv3 to the inside, management VRF, some ACL’s.  I’m looking at the ASR9001 with add-on ports since I need (10) 10gig.  However, I’ve also been running some Arista 7280SE’s for the past 18 months with no issues, and they want me to consider their 7280R since it would give me more ports, in addition to some higher speed ports, which would be nice if I ever want to upgrade some of our peering to 40 or 100gig.

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.
