Arista DCS-7280SRA-48C6 is a 1ru box.??
Has a nominally million route fib, Jericho+ 8GB of packet buffer. control-plane is 8GB of ram andAMD GX-424CC SOC which is 4 core 2.4ghz. We do direct fib injection with bird rather than the arista bgpd but the control-plane is capable of managing quite a few bgp sessions.
the 1/2ru 7280CR2K-30 and 60 are 2m route fib boxes with still heftier control planes but they're a different class of box being all 100G and requiring multi-chip/internal fabrics.
Sounds pretty good - hows your power draw on that thing? Why'd you pick Bird in this case? /kc

For Enterprise/DC, it works great. For service provider, they're not 100% yet. The main issue is going to be around VRFs, as there's no interaction between them (at least in the code version I'm on, that may have changed recently or be changing soon). They'll work great as a P-Router, but if you need a PE with route leaking I'd look at another vendor.
I use a couple pairs of 7280SRs as edge routers/border leaves. Multiple full table feeds without any issue.

So I've been using Arista as layer2 for quite some time, and I'm pretty happy with them. Kicking the idea around to turn on some Layer3 features but I've been hearing some negative feedback. The people that I did hear negative feedback don't use Arista themselves. (they just heard....)
So do we have any Arista L3 people out here that can share some negatives or positives?
Use case: Just some MPLS IPv4/IPv6 routing, l2vpn OSPF/BGP Maybe 20k routes (no full internet routes) 7050 Series 7280 Series
