NETGEAR 8800 Chassis Switch CLI Manual Description Adds a default blackhole route to the routing table. All traffic destined for an unknown IP destination is silently dropped. Syntax Description vr_name multicast-only unicast-only Specifies the virtual router to which the route is added. Specifies only multicast traffic for the route. Specifies only unicast traffic for the route. Default If you do not specify a virtual router, the current virtual router context is used. 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 ::. The packets are silently discarded. In other words, no ICMP message is sent to indicate that the packets are discarded. Example The following command adds a blackhole default route into the routing table: configure iproute add blackhole ipv6 default configure iproute add default configure iproute add default [ | ] {metric} {vr } {multicast-only | unicast-only} Description Adds a default gateway to the routing table. Syntax Description ipv6Gateway metric Specifies a VLAN gateway IPv6 address. Specifies a cost metric. If no metric is specified, the default of 1 is used. Chapter 20. IPv6 Unicast Commands | 907
