Description: Specifies the precedence of a reachable address type. When there are multiple reachable address types associated with the longest match reachable address prefix, the route selection algorithm first attempts to find routes to reachable address types of greatest precedence. Among routes to the same longest match reachable address prefix with the same reachable address type, routes with the least total administrative weight are preferred.

Smaller values take precedence over larger values. Local internal reachable addresses, whether learned through ILMI or as static routes, are given the highest priority (i.e. 1).
