5.5 Configuring OSPFv3 Areas

OSPFv3 supports stub areas and virtual links, the principle and applicable environment of which

are similar to those in OSPFv2.

Configuring a stub area is optional. Not all areas can be configured as stub areas. Generally, a

stub area, which is located at the AS boundary, is a non-backbone area with only one ABR.

Applicable Environment

To reduce the number of LSAs in the network and enhance OSPFv3 extensibility, define OSPFv3

areas. For some non-backbone areas at the edge of ASs, you can define them as stub areas for

further reducing the size of the routing table and the number of LSAs.

Pre-configuration Tasks

Before configuring OSPFv3 area attributes, complete the following tasks:

Data Preparation

To configure OSPFv3 area attributes, you need the following data.

A stub area is a special area in which ABRs do not flood the received AS external routes. Thus,

the number of LSAs is greatly reduced.

Do as follows on each switch that runs OSPFv3 in the stub area:
