This memo describes a backward-compatible technique that may be used
by OSPF (Open Shortest Path First) implementations to advertise
unavailability to forward transit traffic or to lower the preference
level for the paths through such a router.  In some cases, it is
desirable not to route transit traffic via a specific OSPF router.
