Configuring Neighbor Detection Protocol and Static Entries
IPv6 Neighbor Discovery Protocol supersedes IPv4 Address Resolution
Protocol in IPv6 networks. IPv6 nodes on the same network segment use
Neighbor Discovery to discover each other's presence, to determine each
other's link-layer addresses, to find routers and to maintain reachability
information about the paths to active neighbors. The key parameters used
to facilitate this process are the number of attempts made to verify
whether or not a duplicate address exists on the same network segment,
and the interval between neighbor solicitations used to verify reachability
information.
Command Attributes
Protocol Settings
• VLAN – VLAN ID (Range: 1-4093)
• IPv6 ND DAD Attempts – The number of consecutive neighbor
solicitation messages sent on an interface during duplicate address
detection. (Range: 0-600, Default: 1)
- 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 “Creating VLANs” on page 11-8). 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.
