BGP Multipath-Relax Feature

This feature overrides the default protocol behavior specified in RFC-4271 related to route selection tie breakers and the definition of equal cost. In particular, routes with the same AS-path length, but differing AS numbers in the path are not considered equal cost by default. However, with multipath-relax enabled, routes with the same AS-path length can have differing AS number values in the AS-path and still be considered equal cost.
