Parameters
•
value
—The number of neighbor solicitation messages. The acceptable
range is from 0 to 600. Configuring a value of 0 disables duplicate address
detection processing on the specified interface; a value of 1 configures a
single transmission without follow-up transmissions.
Default Configuration
1
Command Mode
Interface Configuration mode
User Guidelines
Duplicate address detection verifies the uniqueness of new Unicast IPv6
addresses before the addresses are assigned to interfaces (the new addresses
remain in a tentative state while duplicate address detection is performed).
Duplicate address detection uses neighbor solicitation messages to verify the
uniqueness of Unicast IPv6 addresses.
The DupAddrDetectTransmits node configuration variable (as specified in
RFC 4862, IPv6 Stateless Address Autoconfiguration) is used to
automatically determine the number of consecutive neighbor solicitation
messages that are sent on an interface, while duplicate address detection is
performed on a tentative Unicast IPv6 address.
The interval between duplicate address detection, neighbor solicitation
messages (the duplicate address detection timeout interval) is specified by
the neighbor discovery-related variable RetransTimer (as specified in RFC
4861, Neighbor Discovery for IPv6), which is used to determine the time
between retransmissions of neighbor solicitation messages to a neighbor
when resolving the address or when probing the reachability of a neighbor.
This is the same management variable used to specify the interval for
neighbor solicitation messages during address resolution and neighbor
unreachability detection. Use the ipv6 nd ns-interval command to configure
the interval between neighbor solicitation messages that are sent during
duplicate address detection.
