Arista 7280SR3K Internet Edge Border Router: Design and Configuration Reference
This document covers the design and configuration of an Arista DCS-7280SR3K series border router at an internet edge. It addresses hardware platform constraints (TCAM allocation, counter feature groups), QoS policy design, MPLS/LDP configuration, and all BGP-layer concerns: session parameters, bestpath policy, peer groups, routing control functions (RCF), convergence optimizations, and BMP telemetry. The platform uses a Jericho2C ASIC and runs EOS with the service routing protocols model multi-agent prerequisite — required for internet-scale BGP. ...
