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.", "pub_date": "March 2017", "keywords": [ "IGP", "OSPF", "TTZ" ], "obsoletes": [], "obsoleted_by": [], "updates": [], "updated_by": [], "see_also": [], "doi": "10.17487/RFC8099", "errata_url": null }
