Information
The description of router lifetime from RFC 2461(http://tools.ietf.org/html/rfc2461) is:
Router Lifetime: 16-bit unsigned integer. The lifetime associated with the default router in units
of seconds. The maximum value corresponds to 18.2 hours. A Lifetime of 0 indicates that the
router is not a default router and SHOULD NOT appear on the default router list. The Router

information contained in other message fields or options. Options that need time limits for their
information include their own lifetime fields.
