Configuring Areas
You configure an OSPF area by setting the parameters described in this section:
Each OSPF area is connected to the backbone by one or more border routers. A
border router can have connections to multiple areas. For instructions on
configuring an area border router, see “Configuring an Area Border Router” on
page 6-58.
Creating an Area
Each OSPF area has a unique identifier. You can use the BCC or Site Manager to
supply the ID of the OSPF area that you want to define.
Using the BCC
To create an OSPF area, go to the global OSPF prompt (for example,
box; ip;
ospf
) and enter:
area area-id
<
area-id>
area-id
is a unique area identifier in dotted-decimal notation.
To display area parameters and their current values, enter:
info
OSPF displays all area attributes and their current values.
