Route redistribution and route maps

Use route maps to control the redistribution of routes between routing domains. Route maps match on the attributes of the routes to redistribute routes that pass the match criteria. The route map can also modify the route attributes using set changes.

The router matches redistributed routes against each route map entry.
  • If there are multiple match statements, the route must pass all match criteria.

  • If a route passes the match criteria defined in a route map entry, actions defined in the entry are executed.

  • If the route does not match the criteria, the router compares the route against subsequent route map entries.

Route processing continues until a match is made or the route is processed by all entries in the route map with no match. If the router processes the route against all entries in a route map with no match, the router accepts the route (inbound route maps) or forwards it (outbound route maps).
