Route maps

Route maps can be used for route redistribution. Route map entries consist of a list of match and set criteria. Match criteria specify match conditions for incoming routes. Set criteria specify the action taken if match criteria are met.

Users can configure multiple entries in the same route map. These entries contain the same route map name and are differentiated by a sequence number. A sequence number will automatically be assigned if user does not provide one.

Create a route map with one or more route map entries arranged by the sequence number under a unique route map name. The route map entry has the following parameters:
  • Sequence number

  • Permission (permit or deny)

  • Match criteria

  • Set changes

By default, a route map processes routes starting from the lowest sequence number to the highest. Other filtering mechanisms include Prefix List, AS Path List, and Community List.
