ip ospf authentication-none
ip ospf message-digest-key md5
NOTE: If all the MD5 keys have been deleted, the authentication type is still MD5,
but you need to configure MD5 keys.
NOTE: To display the password only in encrypted text, use the service
password-encryption command.
NOTE: To disable MD5 authentication for the interface, use the ip ospf
authentication-none command.

Configuring the BFD Protocol for OSPF

The ip ospf bfd-liveness-detection and ipv6 ospf bfd-liveness-detection commands
configure the Bidirectional Forwarding Detection (BFD) protocol for OSPFv2 and
276
Configuring the BFD Protocol for OSPF
Use the no version to set authentication for the interface to none without
removing any configured MD5 key. You can subsequently apply MD5
authentication to the interface without having to reconfigure the key.
See ip ospf authentication message-digest
Use to specify that no authentication is used for the OSPF interface.
Example
host1(config-if)#ip ospf authentication-none
The no version has no effect.
See ip ospf authentication-none
Use to enable MD5 authentication on the OSPF interface and configure the MD5
key.
The MD5 key is a character string up to 16 characters long. You must also specify
a key identifier and whether the key is entered in unencrypted or encrypted
format. If you do not specify which, the string is assumed to be unencrypted.
Example
host1(config-if)#ip ospf message-digest-key 3 md5 0 tre987is
Use the no version to delete an MD5 key from the OSPF interface.
See ip ospf message-digest-key md5
