external network

•Routes that can be advertised with NSSA external LSAs include network destinations outside the AS learned via OSPF, the default route, static routes, routes derived from other routing protocols such as RIP, or directly connected networks that are not running OSPF.

•Also, note that unlike stub areas, all Type-3 summary LSAs are always imported into NSSAs to ensure that internal routes are always chosen over Type-7 NSSA external routes.

Default Cost – This specifies a cost for the default summary route sent into a stub or not-so-stubby area (NSSA) from an Area Border Router (ABR).

Command Usage

•Before you create a stub or NSSA, first specify the address range for an area using the Network Area Address Configuration screen (page 3-249).

•Stubs and NSSAs cannot be used as a transit area, and should therefore be placed at the edge of the routing domain.

•A stub or NSSA can have multiple ABRs or exit points. However, all of the exit points and local routers must contain the same external routing data so that the exit point does not need to be determined for each external destination.

Command Attributes

•Area ID – Identifier for an area, stub or NSSA.

•Area Type – Specifies a normal area, stub area, or not-so-stubby area (NSSA). Area ID 0.0.0.0 is set to the backbone by default. (Default: Normal area)

•Default Cost – Cost for the default summary route sent into a stub from an area border router (ABR). (Range: 0-16777215; Default: 1)

-Note that if you set the default cost to “0,” the router will not advertise a default route into the attached stub.

•Summary – Makes an ABR send a Type-3 summary link advertisement into a stub. (Default: Summary)

-A stub is designed to save routing table space by blocking Type-4 AS summary LSAs and Type 5 external LSAs. If you use the “NoSummary” option to also block Type-3 summary LSAs that advertise the default route for destinations external to the local area or the AS, the stub will become completely isolated.

Note: This router supports up to 16 total areas (either normal transit areas, stubs, or NSSAs).
