S2600E/P CLI Reference Guide Chapter 3 IPv6 Configuration Commands
ipv6 nd
ra-lifetime
Set the lifetime of the device.
ipv6 nd
ra-interval
Set the interval of sending the RA
message.
ipv6 nd
ra-hoplimit
Set the hopcount of the RA message.
3.1.16 ipv6 nd reachable-time
Use this command to set the reachable time after the interface checks the
reachability of the neighbor dynamically learned through NDP. Use the no form
of this command to restore it to the default setting.
ipv6 nd reachable-time milliseconds
no ipv6 nd reachable-time
Parameter Description
Parameter
description
milliseconds
Reachable time for the neighbor in the
range 0 to 3600000 milliseconds.
Default
configuration
The default value in RA is 0 (unspecified); the reachable
time for the neighbor is 30000ms(30s) when the device
discovers the neighbor.
Command
mode Interface configuration mode.
Usage
guidelines
The device checks the unreachable neighbor through the
set time. A shorter time means that the device can check
the neighbor failure more quickly, but more network
bandwidth and device resource will be occupied.
Therefore, it is not recommended to set a too short
reachable time.
The configured value will be advertised through RA and
will be used by the device itself. If the value is set to 0, it
indicates that the time is not specified, that is, the default
value is used.
According to RFC4861, the actual time to reach neighbor
is not consistent with the configured value, ranging from
0.5*configured value to 1.5*configured value.
Examples
Ruijie(config-if)# ipv6 nd reachable-time 1000000
