Abstract
In certain embodiments, performing a defensive procedure involves receiving at a first speaker of a first autonomous system a path advertisement from a second speaker of a second autonomous system. The path advertisement advertises a path from the second speaker of the second autonomous system. It is determined whether the second autonomous system is a stub autonomous system and whether a path length of the path is greater than one. If the second autonomous system is a stub and the path length is greater than one, a defensive measure is performed for the path. Otherwise, a default procedure is performed for the path.
