Command Manual – IPv6 Configuration
H3C S7500E Series Ethernet Switches
Chapter 1 IPv6 Basics Configuration Commands
1-32
Description
Use the
ipv6 nd nud reachable-time
command to configure the neighbor reachable
time on an interface. This time value serves as not only the neighbor reachable time on
the local interface, but also the value of the Reachable Timer field in RA messages sent
by the local interface.
Use the
undo ipv6 nd nud reachable-time
command to restore the default neighbor
reachable time and to specify the value of the Reachable Timer field in RA messages
as 0 so that the number of hops is determined by the host itself, but not specified by the
device.
By default, the neighbor reachable time on the local interface is 30,000 milliseconds
and the Reachable Timer field in RA messages is 0.
Examples
# Set the neighbor reachable time on VLAN-interface 100 to 10,000 milliseconds.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd nud reachable-time 10000
