Usage

• A given host on an interface refreshes the default router lifetime for a specific router each time the host receives an RA from that router.

• A specific router ceases to be a default router candidate for a given host if the default router lifetime expires before the host is updated with a new RA from the router.

Examples

switch(config)# interface 1/1/1
switch(config-if)# ipv6 nd ra lifetime 1200
