Back to this discussion! :) Arista as a viable full-table PE router. Was hoping for better experience reports since last mention. To make the Q bit more general, are there any PE routers yet that can handle 3-8 full feeds and use an amp and 1U or so instead of 5 and 4U? Or we're ito whitebox/ open routers still for that (bird/openbgp?) or microtiks?
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.
