Abstract:
   A transit-only network is defined as a network connecting routers
   only.  In OSPF, transit-only networks are usually configured with
   routable IP addresses, which are advertised in Link State
   Advertisements (LSAs) but not needed for data traffic.  In addition,
   remote attacks can be launched against routers by sending packets to
   these transit-only networks.  This document presents a mechanism to
   hide transit-only networks to speed up network convergence and reduce
   remote attack vulnerability.

   In the context of this document, 'hiding' implies that the prefixes
   are not installed in the routing tables on OSPF routers. In some
   cases, IP addresses may still be visible when using OSPFv2.

   This document updates RFC 2328 and RFC 5340.
