IPv6 Addressing Configuration

Duplicate Address Detection (DAD)

Operating Notes

■ A verified link-local unicast address must exist on a VLAN interface before

the switch can run DAD on other addresses associated with the interface.

■ If a previously configured unicast address is changed, a neighbor adver-

tisement (an all-nodes multicast message--ff02::1) is sent to notify other

devices on the VLAN and to perform duplicate address detection.

■ IPv6 addresses on a VLAN interface are assigned to multicast address

groups identified with well- known prefixes. For more on this topic, refer

to “Multicast Application to IPv6 Addressing” on page 3-21.

■ DAD is performed on all stateful, stateless, and statically configured

unicast addresses, but not on Anycast addresses.

■ Neighbor solicitations for DAD do not cause the neighbor cache of

neighboring switches to be updated.

■ If a previously configured unicast address is changed, a neighbor adver-

tisement is sent on the VLAN to notify other devices, and also for duplicate

address detection.

■ If DAD is disabled when an address is configured, the address is assumed

to be unique and is assigned to the interface.
