Configures the interval, in milliseconds, that a node assumes a neighbor is reachable after receiving a reachability confirmation from the neighbor. Therefore, a neighbor is reachable, after being discovered, for a period specified here. This value is advertised in RAs. Use one of the following options:
<5000-3600000> – Configures an interface-specific value. Specify a value from 5000 - 3600000 milliseconds. The default is 5000 milliseconds.
global – Advertises the neighbor reachable time configured for the system. This is the value configured at the device configuration mode. For more information, see use (profile/device-config-mode-commands) (profile config mode).
