The authentication type used on an interface must match the authentication type defined for the area.

Appendix K Router Platform User Interface Reference

OSPF Interface Policy Page

Table K-110 OSPF Interface Dialog Box (Continued)

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

	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.
