area stub

Description: 

Defines an area as a stub area. A stub area is an OSPF area that carries a default route, intra-area routes, and interarea routes, but does not carry AS external routes. This reduces the size of the area's OSPF database and decreases memory usage for external routers in the stub area. The no version disables this function.

Syntax: 

For OSPFv2:

[ no ] area { areaId | areaIdInt } stub

For OSPFV3:

[ no ] area { areaId | areaIdInt } stub [ no-summary ]

• areaId—OSPF area ID in IP address format
• areaIdInt—OSPF area ID as a decimal value in the range 0-4294967295
• no-summary—Specifies that the summary LSA not be sent into the stub area (IPv6 only)
