Adds the specified route to the multicast routing table. Adds the specified route to the multicast routing table. Adds the specified route to the unicast routing table. Adds the specified route to the unicast routing table. Default If you do not specify a virtual router, the current virtual router context is used. Usage Guidelines Use a mask value of 255.255.255.255 to indicate a host entry. The gateway address must be present on a directly attached subnet, or the following message appears: ERROR: Gateway is not on directly attached subnet The gateway address must be different from the VLAN address, or the following message appears: ERROR: Gateway cannot be own address (x.x.x.x) #where x.x.x.x is the IP address specified Note: Although dynamic unicast routes can be captured in the multicast routing table, unicast static routes cannot be captured in the multicast routing table. To create a static route for the multicast routing table, you must specify the multicast option. Example The following command adds a static address to the routing table: configure iproute add 10.1.1.0/24 123.45.67.1 5 configure iproute add blackhole configure iproute add blackhole [ | ] {multicast | multicast-only | unicast | unicast-only} {vr } Description Adds a blackhole address to the routing table. All traffic destined for a configured blackhole IP address is silently dropped, and no Internet Control Message Protocol (ICMP) message is generated. Chapter 19. IP Unicast Commands | 829
