In the late 1990s and early 2000s, BGP had some serious scaling issues that threatened it’s effectiveness as a protocol that could be used for the global routing table. Significant efforts were made to optimize the resource utilization and convergence time. Our guest in this episode, Daniel Walton, was part of that effort at Cisco and shares his story about the BGP optimizations that were put in place during that time. The optimizations include Peer groups, READONLY mode, update groups, update p...
