Configuring Multi-area Adjacency

This task explains how to create multiple areas on an OSPF primary interface.
Before You Begin
Note You can configure multi-area adjacency on any interface where only two OSF speakers are attached. In
the case of native broadcast networks, the interface must be configured as an OPSF point-to-point type
using the network point-to-point command to enable the interface for a multi-area adjacency.

Configuring Multi-area Adjacency
Purpose
Enters interface configuration mode and associates one or
more interfaces to the area.
Enters OSPF configuration mode.
Creates a VRF instance and enters VRF configuration mode.
Enters area configuration mode and configures an area for
a VRF instance under the OSPF process.
• The area-id argument can be entered in
dotted-decimal or IPv4 address notation, such as area
1000 or area 0.0.3.232. However, you must choose
one form or the other for an area.
Enters interface configuration mode and associates one or
more interfaces to the VRF.
