The deny clause rejects route matches from redistribution. In route-map ospf-to-eigrp, there is one deny clause (with sequence number 10) and two permit clauses.

Route-maps can have permit and deny clauses.

Insert a new clause between two current clauses.Ĭisco recommends that clauses are numbered in intervals of 10 to reserve number spaces to insert clauses in the future, if needed.

Easily delete one specific clause but not affect other parts of the route-map.

Sequence numbers allow you to do these actions: In this example, clauses have sequence numbers 10, 20, and 30. These are the important observations with this example: Redistribute ospf 1 route-map ospf-to-eigrp This is a typical Open Shortest Path First to Enhanced Interior Gateway Routing Protocol (OSPF-to-EIGRP) route-map, applied with a redistribute command: ! Route maps are always applied for inbound traffic, and the route-map does not have any effect on the outbound traffic. If you use a route-map to selectively permit some routes based on their prefix or mask, you typically use more configuration commands to achieve the same goal. Conversely, if you simply need to selectively permit some routes based on their prefix or mask, Cisco recommends that you use an ACL (or equivalent prefix list) directly in the redistribute command. Route-maps are preferred if you intend to either modify route information during redistribution or if you need more powerful capabilities to match capability than an ACL can provide. The differences described in this section identify when to use a route-map in the redistribution process. The dynamic protocol redistribute configuration command allows you to apply either an ACL or a route-map. Fortunately, route-maps that are applied to redistribution behave the same way as ACLs: if the route does not match any clause in a route-map then the route redistribution is denied, as if the route-map contained deny statement at the end. If the end of a route-map is reached when match attempts were made, the result depends on the specific application of the route-map.

Each ACL ends with an implicit deny statement, by design convention there is no similar convention for route-maps.

For example, a route-map can verify if the type of route is internal or if it has a specific tag.

Route-maps are more flexible than ACLs and can verify routes based on criteria which ACLs cannot verify.

Typical route-maps not only permit (some) redistributed routes but also modify information associated with the route when it is redistributed into another protocol.

Applied to redistribution, an ACL determines if a particular route can (route matches ACLs permit statement) or cannot (matches deny statement) be redistributed. An ACL either permits or denies input data.

The main result from the evaluation of an access list is a yes or no answer.

Route-maps frequently use ACLs as the matched criteria.

These are possible differences between route-maps and ACLs: The same route-map applied to different tasks can have a different interpretation.

They are generic mechanisms-criteria match, and match interpretation are dictated by the way they are applied.

A list scan is aborted once the first statement match is found, and an action associated with the statement match is performed. Evaluation of ACL or route-maps consists of a list scan, in a predetermined order, and an evaluation of the criteria of each statement that matches.

They are an ordered sequence of individual statements each has a permit or deny result.

These are some of the traits common to both mechanisms: Route-maps have many features in common with widely known access control lists (ACLs).
