Purpose
Enters configuration mode.
Enters interface configuration mode.
Enables interface authentication mode for OSPFv2 for
either cleartext or message-digest type. Overrides
area-based authentication for this interface. All
neighbors must share this authentication type.
(Optional) Configures interface authentication to use
key chains for OSPFv2. See the Cisco Nexus 7000
Series NX-OS Security Configuration Guide, Release
4.x for details on key chains.
(Optional) Configures simple password authentication
for this interface. Use this command if the
authentication is not set to key-chain or
message-digest.
The options are as follows:
0—configures the password in clear text.
•
3—configures the pass key as 3DES encrypted.
•
7—configures the key as Cisco type 7 encrypted.
(Optional) Configures message digest authentication
for this interface. Use this command if the
authentication is set to message-digest.The key-id
range is from 1 to 255. The MD5 options are as
follows:
• 0—configures the password in clear text.
3—configures the pass key as 3DES encrypted.
•
7—configures the key as Cisco type 7 encrypted.
•
(Optional) Displays OSPF information.
(Optional) Saves this configuration change.
