Modifying an Area ID
In an AS that contains multiple areas, you must assign a unique ID to each area.
You specify an ID when you define the area. You can use the BCC to change the
ID.
Using the BCC
Navigate to an OSPF interface prompt and enter:
area
id
id is an area identifier expressed in dotted-decimal notation.
Configuring Authentication
OSPF provides a measure of security for an area through the use of passwords. If
an area is configured to use authentication, all OSPF interfaces configured in that
area must be configured with a password. The password must be identical on each
interface connected to the same network. Different networks can have different
passwords.
In such an area, a router that receives a packet verifies the password before doing
anything else with the packet. Unauthorized routers are not allowed to
communicate with the OSPF system.
By default, authentication is disabled in an area. You can use the BCC or Site
Manager to enable authentication and specify a password.
Using the BCC
To enable authentication, navigate to the area-specific prompt and enter:
authentication-type simplepassword
If you have enabled authentication on the area, you can specify a password.
Navigate to the OSPF interface-specific prompt and enter:
authentication-key
string
string is any ASCII string up to eight characters long.
