Abstract
A system related to black hole filtering is provided. The system can allow a dynamic routing protocol on a network device to determine whether a route learned by the dynamic routing protocol is a black hole route. The route may be learned through another source. In response to a determination that the route is the black hole route, the dynamic routing protocol may generate a routing update that indicates the route as the black hole route. The dynamic routing protocol may then advertise the routing update to each neighbor network device.
