Destination based RTBH (remote triggered blackholing) is used on edge devices in a network to prevent DOS attack on a target network (IP/prefix) by blackholing/dropping the traffic destined towards this target. One of the ways to achieve this is through a trigger router sending a routing update for the prefix under attack to the edge routers configured for black hole filtering. The next-hop of such routing updates ends up getting resolved to a null/drop interface on the edge device, which results in blackholing all traffic destined towards this target network.
