#6: Lifetime field length should be 16bit for ND compatibility

 Currently draft-ietf-mif-dhcpv6-route-option-04 specifies that the
 lifetime of a route (and implicitely of a default route) is to be 32bit
 length field.

 On another hand, the currently implemented default routes are
 implemented according to ND Neighbor Discovery, which uses route_r_
 lifetime on 16bit (RFC 4861 search "Router Lifetime").

 I think this is an issue.  It generates additional work to the
 implementer.  If one agrees that it is good to store the DHCP default
 route in the existing ND data structures, then one notices a conversion
 is needed.  If these lifetime fields were expressed in the same number
 of bits (preferably 16bit, because that exists already) then the
 implementer would be relieved from conversion work.
