This tutorial introduces service providers to some more advanced BGP features and techniques to aid with operating their networks within the Internet. After a brief recap of iBGP, eBGP, and common attributes, the tutorial will look at the various scaling techniques available, when to use BGP instead of an IGP, and examine policy options available through the use of local preference, MED, and communities. The tutorial will then briefly cover some basic multihoming techniques, before finishing with a look at some of the facilities available for debugging problems in BGP networks.
