NETGEAR 8800 Chassis Switch CLI Manual Default N/A. Usage Guidelines NSSAs are similar to the existing OSPF stub area configuration option, but have the following two additional capabilities: • External routes originating from an ASBR connected to the NSSA can be advertised within the NSSA. • External routes originating from the NSSA can be propagated to other areas, including the backbone area, if translated to type 5 LSAs. When configuring an OSPF area as an NSSA, the translate option should only be used on NSSA border routers, where translation is to be enforced. If translate is not used on any NSSA border router in a NSSA, one of the ABRs for that NSSA is elected to perform translation (as indicated in the NSSA specification). The option should not be used on NSSA internal routers. Doing so inhibits correct operation of the election algorithm. Example The following command configures an OSPF area as an NSSA: configure ospf area 10.1.1.0 nssa summary stub-default-cost 10 translate configure ospf area stub stub-default-cost configure ospf area stub [summary | nosummary] stub-default-cost Description Configures an OSPF area as a stub area. Syntax Description area-identifier summary nosummary cost Specifies an OSPF area. Specifies that type-3 can be propagated into the area. Specifies that type-3 cannot be propagated into the area. Specifies a cost metric. Default N/A. 1002 | Chapter 23. OSPF Commands

OSPF Commands

NETGEAR 8800 Chassis Switch CLI Manual

Default

N/A.

Usage Guidelines

NSSAs are similar to the existing OSPF stub area configuration option, but have the following

two additional capabilities:

•

External routes originating from an ASBR connected to the NSSA can be advertised

within the NSSA.

•

External routes originating from the NSSA can be propagated to other areas, including

the backbone area, if translated to type 5 LSAs.

When configuring an OSPF area as an NSSA, the translate option should only be used on

NSSA border routers, where translation is to be enforced. If translate is not used on any

NSSA border router in a NSSA, one of the ABRs for that NSSA is elected to perform

translation (as indicated in the NSSA specification). The option should not be used on NSSA

internal routers. Doing so inhibits correct operation of the election algorithm.

Example

The following command configures an OSPF area as an NSSA:

configure ospf area 10.1.1.0 nssa summary stub-default-cost 10 translate

configure ospf area stub stub-default-cost

configure ospf area <area-identifier> stub [summary | nosummary] stub-default-cost <cost>

Description

Configures an OSPF area as a stub area.

Syntax Description

Default

N/A.

area-identifier

Specifies an OSPF area.

summary

Specifies that type-3 can be propagated into the area.

nosummary

Specifies that type-3 cannot be propagated into the area.

cost

Specifies a cost metric.
