O CONFIGURE AUTHENTICATION FOR AN INTERFACE
OSPF packets can be authenticated to prevent inadvertent or intentional
introduction of bad routing information. OSPF authentication on OmniAccess
5740 USG supports both clear text as well as MD5 cryptographic checksum.
The “no” form of these commands negates the configured authentication.

Command (in ICM) Description
ip ospf authentication
[message-digest|null]
This command is used to enable
authentication for OSPF.
Use ‘message-digest’ keyword to
enable MD5 authentication.
The default authentication mode is Plain
Text authentication.
If ‘null’ keyword is used, then no
authentication is used. It is used to
override authentication configured for an
area.
ip ospf authentication-key
{<0-0>|<password-key>}
This command assigns an authentication
password to be used by OSPF routers
on a network segment.
Password need not be the same
throughout the area but needs to be the
same between neighbors.
ip ospf message-digest-key <1-
255> md5 <key>
Enables OSPF MD5 authentication. The
values for the key-id and key arguments
must match the values specified for other
neighbors on a network segment.
