Command Mode
Interface configuration
Usage Guideline
This command creates a password (key) that is inserted into the OSPF header
when the router originates routing protocol packets. Assign a separate password
to each network for different interfaces. All neighboring routers on the same
network with the same password exchange OSPF routing data.
Use the ip ospf authentication command to enable authentication. Simple
password authentication allows a password to be configured for each interface.
Configure the routers in the same routing domain with the same password.
Example
In the following example, an authentication key test is created on interface VLAN
1 in area 0. Note that first authentication is enabled for area 0.
Verify the settings by entering the
show ip ospf interface
command
Syntax Description
