configure neighbor-discovery cache {reachable-time [auto | {reachable_time [seconds | milliseconds]}]}

Description

Sets the value for Neighbor Discovery Protocol (NDP) reachable time

Syntax Description


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).

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.

Example

The following example sets the reachable time to 500,000 seconds:

configure neighbor-discovery cache reachable-time 500000 seconds
