ipv6 nd ra reachable-time

Syntax

ipv6 nd ra reachable-time [1000 - 3600000|unspecified]

Description

VLAN or tunnel context command for all hosts on the VLAN or tunnel to configure as the reachable time duration for a given neighbor after receiving a reachability confirmation from the neighbor. This value is used to ensure a uniform reachable time among hosts on the VLAN or tunnel by replacing the individually configured settings on various hosts on the VLAN.

Options

1000 - 3600000: Reachable time in milliseconds.
unspecified: Configures the reachable time to zero, which disables the reachable-time setting in RAs on the current VLAN.

NOTE:

If multiple routers on the same VLAN or tunnel are configured to advertise a reachable time, all such routers should use the same reachable-time setting.
