Parameters
time : Specifies the router lifetime in the range of 0 to 9000 seconds. If the value is set to 0, the
router does not act as the default router.
Usage guidelines
The router lifetime in RA messages specifies how long the router sending the RA messages acts as
the default router. Hosts receiving the RA messages check this value to determine whether to use
the sending router as the default router. If the router lifetime is 0, the router cannot be used as the
default router.
The router lifetime in RA messages must be greater than or equal to the advertising interval.
