Parameter value: Neighbor reachable time in milliseconds, in the range of 1 to 3,600,000.

Description Use the ipv6 nd nud reachable-timecommand 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-timecommand 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.

Example # Set the neighbor reachable time on Ethernet1/0 to 10,000 milliseconds.
