Authentication Type—The authentication type used by the selected interface:
• MD5—Uses the MD5 hash algorithm for authentication. This is the
default.
• Clear Text—Uses a clear text password for authentication.
• None—Uses no authentication.
Note The authentication type used on an interface must match the
authentication type defined for the area.
Note Use plain text authentication only when security is not an issue, for
example, to ensure that misconfigured hosts do not participate in
routing.
• Key ID—Available only when MD5 is selected as the authentication
type.
The identification number of the authentication key. This number must
be shared with all other devices sending updates to, and receiving
updates from, the selected device. Valid values range from 1 to 255.
• Key—The shared key used for authentication (MD5 or clear text). This
key must be shared with all other devices sending updates to, and
receiving updates from, the selected device. Enter this key again in the
Confirm field.
When using clear text, the key can include any continuous string of
characters that can be entered from the keyboard (up to 8 bytes).
When using MD5, the key can include alphanumeric characters only (up
to 16 bytes).
Cost The cost of sending packets over this interface. A value entered here
overrides the default calculated cost (10 8 /bandwidth in bits per second).
Valid values range from 1 to 65535.
