Interdomain Routing
slides-edu-interdomain-routing-01

The Internet's routing architecture uses a division of the network into discrete routing domains, or Autonomous Systems. What is appropriate for a routing protocol to operate within a routing domain is somewhat different to the requirements for routing between these domains. This tutorial will look at Inter-Domain Routing (IDR) from the perspective of the IETF work in this area. The tutorial will cover the basics of routing protocol operation and look at the specification of the Border Gateway Protocol (BGP) and the various refinements that the IETF has made in recent times to this protocol, and some of the current burning issues in inter-domain routing. This is not a tutorial about how to deploy or operate BGP in your network!
