Hierarchy Level


Do not forward packets addressed to this destination. Instead, drop the packets, do not send ICMP unreachable messages to the packets’ originators, and install a reject route for this destination into the routing table.

To propagate static routes into the routing protocols, include the discard statement when you define the route, along with a routing policy.


In other vendors’ software, a common way to propagate static routes into routing protocols is to configure the routes so that the next-hop routing device is the loopback address (commonly, However, configuring static routes in this way (by including a statement such as route address/mask-length next-hop does not propagate the static routes, because the forwarding table ignores static routes whose next-hop routing device is the loopback address.


When an aggregate route becomes active, it is installed in the routing table with a reject next hop, which means that ICMP unreachable messages are sent.
