Configuring Duplicate Address Detection Attempts - Juniper IGP - CONFIGURATION GUIDE V11.1.X Configuration Manual

NOTE: This command is redundant when configuring Neighbor Discovery over
Ethernet, because neighbor solicitations and advertisements are automatically sent
on Ethernet interfaces.

Configuring Duplicate Address Detection Attempts

The duplicate address detection feature helps to verify that a new unicast IPv6 address
is unique in the network. The router sends the IPv6 address in its neighbor solicitation
messages. However, the router relies on the receiving device to understand the
address duplication and does not prompt a conflict if the address already exists.
The CLI allows you to specify the number of consecutive neighbor solicitation
messages that the router sends from the IPv6 interface.
ipv6 nd dad attempts
host1(config)#ipv6 nd
Enable IPv6 neighbor proxy.
host1(config-if)#ipv6 nd proxy
Use to enable or disable Neighbor Discovery proxy.
Example
host1(config-if)#ipv6 nd proxy
Use the no version of this command to disable Neighbor Discovery proxy.
See ipv6 nd proxy
Use to specify the number of consecutive neighbor solicitation messages that
the router sends from the IPv6 interface.
Use an attempt value of zero (0) to disable duplicate address detection on the
current interface.
The router suspends duplicate address detection on interfaces that are
administratively down.
Example
host1(config-if)#ipv6 nd dad attempts 10
Use the no version of this command to restore the default number of attempts
to one (1).
