ExtremeWare XOS 11.5 Command Reference Guide
1434
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.
Syntax Description
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 command configures the default-lifetime to be 3600 seconds for the VLAN top_floor:
configure vlan top_floor router-discovery default-lifetime 3600
History
This command was first available in ExtremeWare XOS 11.2.
Platform Availability
This command is available on all platforms.
vlan_name Specifies an IPv6 configured VLAN.
