Usage guidelines
If a device does not receive a response from the peer within the specified interval, the device
re-sends an NS message.
The value specified by this command serves as the interval for the local interface to retransmit an NS
message. It also serves as the value in the Retrans Timer field in RA messages sent by the local
interface.
Examples
# Specify VLAN-interface 100 to retransmit NS messages at an interval of 10000 milliseconds.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd ns retrans-timer 10000
Related commands
display ipv6 interface
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 value
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
value: 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 value specified by this command serves as the neighbor reachable time on the local interface. It
also serves as the value in the Reachable Time field in RA messages sent by the local interface.
Examples
# Set the neighbor reachable time on VLAN-interface 100 to 10000 milliseconds.
