1800 seconds.
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.
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
