NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines While a default route is for forwarding traffic destined to an unknown IP destination, and a blackhole route is for discarding traffic destined to a specified IP destination, a default blackhole route is for discarding traffic to the unknown IP destination. Using this command, all traffic with an unknown destination is discarded. The default blackhole route is treated like a permanent entry in the event of a switch reset or power off/on cycle. The default blackhole route's origin is "b" or "blackhole" and the gateway IP address for this route is ::. Example The following command deletes a blackhole default route from the routing table: configure iproute delete blackhole default configure iproute delete default configure iproute delete default [ | ] {vr } Description Deletes a default gateway from the routing table.
