228 IP Addressing CommandsExampleThe following example displays the current state of the IPv6 routing table.ipv6 nd dad attemptsThe ipv6 nd dad attempts Interface Configuration mode command configures the number ofconsecutive neighbor solicitation messages that are sent on an interface while duplicate addressdetection is performed on the unicast IPv6 addresses of the interface. Use the no form of this commandto return the number of messages to the default value.Syntax• ipv6 nd dad attempts attempts-number• no ipv6 nd dad attempts• attempts-number — The number of neighbor solicitation messages. Configuring a value of 0disables duplicate address detection processing on the specified interface; a value of 1 configures asingle transmission without follow-up transmissions. (Range: 0 - 600)Default ConfigurationDuplicate address detection on unicast IPv6 addresses with the sending of one (1) neighborsolicitation message is enabled.Command ModeInterface configuration (Ethernet, VLAN, Port-channel). Cannot be configured for a range ofinterfaces (range context).Console> show ipv6 routeCodes: L - Local, S - Static, I - ICMP, ND - Router AdvertismentThe number in the brackets is the metric.S ::/0 via fe80::77 [0] VLAN 1 Lifetime InfiniteND ::/0 via fe80::200:cff:fe4a:dfa8 [0] VLAN 1 Lifetime 1784 secL 2001::/64 is directly connected, g2 Lifetime InfiniteL 2002:1:1:1::/64 is directly connected, VLAN 1 Lifetime 2147467secL 3001::/64 is directly connected, VLAN 1 Lifetime InfiniteL 4004::/64 is directly connected, VLAN 1 Lifetime InfiniteL 6001::/64 is directly connected, g2 Lifetime Infinite5400_CLI.book Page 228 Wednesday, December 17, 2008 4:33 PM
