RFC 2461: Host Description:
4.2. Router Advertisement Message Format 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 Lifetime applies only to the router's usefulness as a default router; it does not apply to information contained in other message fields or options. Options that need time limits for their information include their own lifetime fields. Router Description: 6.2.1. Router Configuration Variables AdvDefaultLifetime The value to be placed in the Router Lifetime field of Router Advertisements sent from the interface, in seconds. MUST be either zero or between MaxRtrAdvInterval and 9000 seconds. A value of zero indicates that the router is not to be used as a default router. Default: 3 * MaxRtrAdvInterval When sending RA the maximum lifetime that can be advertised is 9000 seconds, but when receiving the RA in Host, RFC does not specify any limit other than 18.2 hr(65535 ushort max value). A router sending RA with a lifetime of more than 9000 seconds is an RFC violation. But at the same time a host discarding such an RA is also RFC violation Please guide me in this regard...
