    Defining the Conditions for Redistributing Routes Using a Route Map

    You can use the route-map command to define the conditions for redistributing routes from one routing protocol to another, and for filtering or modifying updates sent to or received from peers.

    Each route-map command has a list of match and set commands associated with it. That is, the route map itself consists of a set of clauses; each clause (also called an entry) consists of a match or set command:

    • The match commands specify the match criteria—that is, the conditions under which redistribution is allowed for the current route map.
    • The set commands specify the set actions—that is, the redistribution actions to perform if the criteria enforced by the match commands is met.

    You can specify match and set clauses to modify attributes of redistributed routes. Use route maps when you want complete control over how routes are redistributed between routing processes.

    You can specify the destination routing protocol with the router command and the source routing protocol with the redistribute command.

    To configure the route map:

    • Issue the route-map command in Global Configuration mode.
    host1(config)#route-map nyc1 permit 10

    Use the no version to delete the route map.
