BGP is an essential part of ISP routing, but successful ISP routing includes far more than the protocol itself. Obtaining and managing address space, obtaining an AS number, and creating and registering routing policies are critical parts of operations. Understanding convergence requirements and other performance objectives for ISP routers also is important. This presentation will focus on BGP in the larger context, rather than being a basic protocol and configuration guide, as in Berkowitz' previous NANOG tutorials.
