Parameters
value: Specifies the interval value in the range of 1000 to 4294967295 milliseconds.
Usage guidelines
If a device does not receive a response from the peer within the specified interval, the device
resends an NS message. The device retransmits an NS message at the specified interval and uses
the interval value to fill the Retrans Timer field in RA messages to be sent.
Examples
# Specify VLAN-interface 100 to retransmit NS messages every 10000 milliseconds.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd ns retrans-timer 10000

ipv6 nd nud reachable-time
Use ipv6 nd nud reachable-time to set the neighbor reachable time on an interface.
Use undo ipv6 nd nud reachable-time to restore the default.
Syntax
ipv6 nd nud reachable-time time
undo ipv6 nd nud reachable-time
Default
The neighbor reachable time on the local interface is 30000 milliseconds, and the value of the
Reachable Time field in RA messages is 0. The reachable time is determined by the receiving
device.

Parameters
time: Specifies the neighbor reachable time in the range of 1 to 3600000 milliseconds.
Usage guidelines
If the neighbor reachability detection shows that a neighbor is reachable, the device considers the
neighbor reachable within the specified reachable time. If the device must send a packet to the
neighbor after the specified reachable time expires, the device reconfirms whether the neighbor is
reachable. The device sets the specified value as the neighbor reachable time on the local interface
and uses the value to fill the Reachable Time field in RA messages to be sent.
Examples
# Set the neighbor reachable time on VLAN-interface 100 to 10000 milliseconds.
