Title : IS-IS Extended Hierarchy

Pages : 19

Abstract:
The IS-IS routing protocol was originally defined with a two level
hierarchical structure. This was adequate for the networks at the
time. As we continue to expand the scale of our networks, it is
apparent that additional hierarchy would be a welcome degree of
flexibility in network design.
This document defines IS-IS Levels 3 through 8.
