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.
