A route map is a set of statements that the device applies in sequential order to a route.
Each statement in the route map defines a condition that is compared to the route. A
route is compared to each statement in a specified route map in order of increasing
sequence number until there is a match, then the action specified by the statement is
applied. If the route matches the condition in the route map statement, the route is either
permitted or rejected.
A route map statement can also modify certain attributes of a matching route. There is
an implicit deny at the end of every route map; that is, if a route does not match any entry
in the route map, the route is rejected.
For each match condition, you specify whether a route that matches the condition is
accepted (permitted) or rejected (denied). If a route matches a condition and is permitted,
you can optionally set attribute values for the route. You can configure additional entries
for the same route map, specifying a different sequence number for each entry.
Route Map Match Conditions
