Abstract
In general, techniques are described for a dynamic prefix list for route filtering. In one example, a network device comprises a control unit comprising one or more processors; one or more interface cards coupled to the control unit; a routing protocol process configured to execute on the control unit to exchange, using the interface cards, routing protocol advertisements with a peer network device in accordance with a routing protocol; and a configuration database comprising a routing policy that references a dynamic prefix list comprising one or more prefixes. The routing policy includes at least one action for application to routes for import or export, by the network device via a routing protocol, that match any of the one or more prefixes of the dynamic prefix list. The dynamic prefix list comprises a routing table to store the one or more prefixes, the routing table separate from the configuration database.
