Abstract Abstract
This document specifies a topology-transparent zone in an IS-IS area. This document specifies a topology-transparent zone in an IS-IS area.
A zone is a subset (block/piece) of an area, which comprises a group A zone is a subset (block/piece) of an area, which comprises a group
of routers and a number of circuits connecting them. It is of routers and a number of circuits connecting them. It is
abstracted as a virtual entity such as a single virtual node or zone abstracted as a virtual entity such as a single virtual node or zone
