Follow these steps to configure the attempts to send an NS message for duplicate
address detection:
Enter system view
Enter VLAN interface view
Configure the attempts to
send an NS message for
duplicate address
detection
IV. Configuring the NS Interval
After a device sends an NS message, if it does not receive a response within a specific
period, the device will send another NS message. You can configure the interval for
sending NS messages.
Follow these steps to configure the NS interval:
Enter system view
Enter VLAN interface
view
Specify the NS interval
V. Configuring the neighbor reachable timeout time on an interface
After a neighbor passed the reachability detection, the device considers the neighbor to
be reachable in a specific period. However, the device will examine whether the
neighbor is reachable again when there is a need to send packets to the neighbor after
the neighbor reachable timeout time elapsed.
Follow these steps to configure the neighbor reachable timeout time on an interface:
Enter system view
Enter VLAN interface view
