Route-map
A route-map is a construct used in Cisco network devices that allows you to define a set of sequential rules or statements, each with a permit or deny condition for the purpose of matching, filtering, modifying, and acting upon traffic of prefixes.
Route-maps can be applied to many router operations such as route redistribution, prefix filtering, policy based routing and others.
Route-maps match traffic or prefixes by referencing access lists, prefix lists, distribution lists, specific IP addresses, or a myriad of other characteristics. This traffic can then be acted upon in a multitude of ways.
Route-maps are very powerful constructs allowing you to employ many different types of filtering and manipulation of traffic and shared prefixes between network devices.
