Border Gateway Protocol

A networking enthusiast has highlighted that RFC 1267, the document defining Border Gateway Protocol version 3, was published in October 1991. BGP remains the routing protocol that ties the internet together, so reminders of its early specifications draw interest from engineers interested in networking history, open-source networking, and how the internet's core infrastructure evolved over more than three decades.

RFC 8654, the standard defining extended message support for the Border Gateway Protocol (BGP), was published in October 2019. BGP is the routing protocol that holds the global internet together, and the update allows larger BGP messages than the original specification permitted. A networking guide covering IP routing and BGP internals is being shared and discussed among open source and Linux networking enthusiasts.
