Configuring the 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.

• 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)
