Command Manual – IPv6 ConfigurationH3C S7500E Series Ethernet Switches Chapter 1 IPv6 Basics Configuration Commands1-32DescriptionUse the ipv6 nd nud reachable-time command to configure the neighbor reachabletime on an interface. This time value serves as not only the neighbor reachable time onthe local interface, but also the value of the Reachable Timer field in RA messages sentby the local interface.Use the undo ipv6 nd nud reachable-time command to restore the default neighborreachable time and to specify the value of the Reachable Timer field in RA messagesas 0 so that the number of hops is determined by the host itself, but not specified by thedevice.By default, the neighbor reachable time on the local interface is 30,000 millisecondsand the Reachable Timer field in RA messages is 0.Examples# Set the neighbor reachable time on VLAN-interface 100 to 10,000 milliseconds. system-view[Sysname] interface vlan-interface 100[Sysname-Vlan-interface100] ipv6 nd nud reachable-time 100001.1.29 ipv6 nd ra haltSyntaxipv6 nd ra haltundo ipv6 nd ra haltViewInterface viewParametersNoneDescriptionUse the ipv6 nd ra halt command to suppress RA messages.Use the undo ipv6 nd ra halt command to disable the RA message suppression.By default, RA messages are suppressed.Examples# Suppress RA messages on VLAN-interface 100. system-view[Sysname] interface vlan-interface 100[Sysname-Vlan-interface100] ipv6 nd ra halt
