fsMIStdIpDefaultRouterLifetime

The remaining length of time, in seconds, that this router
will continue to be useful as a default router.  A value of
zero indicates that it is no longer useful as a default
router.  It is left to the implementer of the MIB as to
whether a router with a lifetime of zero is removed from the
list.
              
For IPv6, this value should be extracted from the router
advertisement messages.
