Abstract

Networks expand as business grows and traffic increases. For scalability and manageability, a hierarchical network architecture is usually deployed in OSPF networks by regrouping routers into areas, which is often challenging and causes service interruptions.

                      OSPF Topology-Transparent Zone

Abstract

   This document presents a Topology-Transparent Zone (TTZ) in an OSPF    area.  A TTZ comprises a group of routers and a number of links    connecting these routers.  Any router outside of the zone is not    aware of the zone.  A TTZ hides the internal topology of the TTZ from    the outside.  It does not directly advertise any internal information    about the TTZ to a router outside of the TTZ.  The information about    the links and routers such as a link down inside the TTZ is not    advertised to any router outside of the TTZ.
