configure vlan router-discovery default-lifetime

configure vlan vlan_name router-discovery {ipv6} default-lifetime defaultlifetime

Description

Configures the router lifetime value sent in router discovery advertisements on the VLAN (Virtual LAN).

Syntax Description

vlan_name Specifies an IPv6 configured VLAN.
defaultlifetime Specifies the router lifetime. Range is 0, or max-interval to 9000 seconds.

Default

1800 seconds.

Usage Guidelines

This command configures the router lifetime value to be included in the router advertisement messages.

The value is specified in seconds and is either 0, or between max-interval and 9000 seconds. A value of 0 indicates that the router is not to be used as a default router.

After a host sends a router solicitation, and receives a valid router advertisement with a non-zero router lifetime, the host must desist from sending additional solicitations on that interface, until an event such as re-initialization takes place.

Example

The following example configures the default-lifetime to be 3600 seconds for the VLAN "top_floor":

configure vlan top_floor router-discovery default-lifetime 3600
