Configuring IP, ARP, RIP, and OSPF Services

A-50

117356-E Rev 00

Parameter: Import AS Extern

Path: Configuration Manager > Protocols > IP > OSPF/MOSPF > Areas

Default: Import External

Options: Import External

Import No External

Import NSSA

Function: Indicates whether or not an area imports AS external LSAs. If an area

imports type 5 AS external LSAs, it is a normal (non-stub) area. If an area

does not import AS external LSAs, it is a stub area. If an area imports type 7

external LSAs only, it is an NSSA (not-so-stubby area).

Instructions: Set to Import No External if you want to configure a stub area. Set to Import

NSSA if you want to configure a not-so-stubby area (NSSA). Otherwise,

accept the default, Import External, to configure a normal area.

MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.3.2.1.6

Parameter: Stub Default Metric

Path: Configuration Manager > Protocols > IP > OSPF/MOSPF > Areas

Default: 1

Options: 1 to 16777215

Function: When an area border router (ABR) is connected to a stub area, it generates a

type 3 summary LSA to the area specifying the default route. When an ABR

is connected to an NSSA, it generates a type 3 summary LSA if type 3 LSAs

are not imported to the NSSA. However, if type 3 LSAs are imported to the

NSSA, the ABR generates type 7 LSAs specifying the default route. The stub

metric is the cost of the type 3 or type 7 default route. This parameter has

meaning only when the Import AS Extern parameter is set to Import No

External or Import NSSA.

Instructions: Either accept the stub metric default value, 1, or supply the appropriate stub

metric value.
