Command History
Usage Guidelines
The password created by this command is used as a key that is inserted directly into the OSPF header
when Cisco NX-OS originates routing protocol packets. You can assign a separate password to each
network on a per-interface basis. All neighboring routers on the same network must have the same
password to be able to exchange OSPF information.
Note
Cisco NX-OS uses this key when you enable authentication for an interface with the
ip ospf
authentication
interface configuration command or if you configure the area for authentication with the
area authentication
command in router configuration mode.
This command requires the LAN Base Services license.
Examples
This example shows how to configure an unencrypted authentication key with the string yourpass:
switch#
configure terminal
switch(config)#
interface ethernet 1/5
switch(config-if)#
no switchport
switch(config-if)#
ip ospf authentication-key yourpass
switch(config-if)#
