History   Command introduced in Version 2.2.3.

Usage   An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same area identification.. A router within an area must maintain a topological database for the area to which it belongs. The router doesn't have detailed information about network topology outside of its area, thereby reducing the size of its database.

Areas limit the scope of route information distribution. It is not possible to do route update filtering within an area. The link-state database (LSDB) of routers within the same area must be synchronized and be exactly the same. However, route summarization and filtering is possible between different areas. The main benefit of creating areas is a reduction in the number of routes to propagate through the filtering and the summarization of routes.

Examples  To modify an OSPF area, 0, and change the stub type to nssa, use the following syntax:

CLI network-admin@switch > vrouter-ospf-area-modify vrouter-name vrouter-ospf area 0 stub-type nssa
