Command Usage
◆
Configuring a value of 0 disables duplicate address detection.
◆
Duplicate address detection determines if a new unicast IPv6 address already
exists on the network before it is assigned to an interface.
◆
Duplicate address detection is stopped on any interface that has been
suspended (see the
command). While an interface is suspended, all unicast
IPv6 addresses assigned to that interface are placed in a “pending” state.
Duplicate address detection is automatically restarted when the interface is
administratively re-activated.
◆
An interface that is re-activated restarts duplicate address detection for all
unicast IPv6 addresses on the interface. While duplicate address detection is
performed on the interface’s link-local address, the other IPv6 addresses remain
in a “tentative” state. If no duplicate link-local address is found, duplicate
address detection is started for the remaining IPv6 addresses.
◆
If a duplicate address is detected, it is set to “duplicate” state, and a warning
message is sent to the console. If a duplicate link-local address is detected, IPv6
