EXAMPLE
The following configures five neighbor solicitation attempts for addresses
configured on VLAN 1. The show ipv6 interface command indicates that the
duplicate address detection process is still on-going.
Console(config)#interface vlan 1
Console(config-if)#ipv6 nd dad attempts 5
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled
