Sets the value for Neighbor Discovery Protocol (NDP) reachable time
|reachable-time||Specifies setting the NDP reachable time.|
|reachable_time||Sets the value for the NDP reachable time (range is 1–1,474,515,000 millisecond or 1–1,474,515 second).|
|auto||Specifies having the NDP reachable time set automatically to 3/4 of the configured NDP timeout (default).|
|milliseconds||When setting the reachable time value, specifies milliseconds as the time unit (range is 1–1,474,515,000).|
|seconds||When setting the reachable time value, specifies seconds (range is 1–1,474,515) as the time unit (default).|
The default setting is for the reachable time to be set automatically to 3/4 of the configured NDP timeout. If you set the time manually, the default unit of measure for the value is seconds.
