Abstract
A network device uses a routing policy to assess network routes, such as BGP routes. The routes can be routes advertised by neighbors to be programmed in a routing table of the network device. The network routes can be previously programmed routes (e.g., in a routing table) in the network device to be advertised to its neighbors. The routing policy includes routing control functions (RCF functions) for assessing a network route. An RCF function can be invoked with arguments, which allows the user to deploy some common logic (e.g., matching a community list, modifying a local preference value, etc.) with different sets of input values without having to write separate functions for each set of input values.
