1. A method for summarizing port viability information in a communication network, the method comprising:
- establishing a port viability summarization for ports in the communication network, the port viability summarization being used to establish links to use along a routing path;
determining a routing path using the port viability summarization;
detecting a failed route establishment for the routing path;
decreasing the amount of summarization for at least one port determined to have a non-viable link.

Abstract
A method and apparatus for summarizing port viability information in a communication network. A port viability summarization in the form of a table or matrix is established for ports in the communication network in which the port viability summarization is used to establish links to use along a routing path. A routing path is determined using the port viability summarization. A failed route establishment for the routing path is detected. The amount of summarization is decreased for at least one port determined to have a non-viable link.
