ip ospf
authentication
This command specifies the authentication type used for an interface.
Enter this command without any optional parameters to specify plain text
(or simple password) authentication. Use the
no
form to restore the
default of no authentication.

authentication
ip-address
- IP address of the interface. Enter this parameter to
specify a unique authentication type for a primary or secondary IP
address associated with the current VLAN. If not specified, the
command applies to all networks connected to the current interface.
message-digest
- Specifies message-digest (MD5) authentication.
null
- Indicates that no authentication is used.

◆
Use authentication to prevent routers from inadvertently joining an
unauthorized area. Configure routers in the same area with the same
password or key. All neighboring routers on the same network with the
same password will exchange routing data.
◆
This command creates a password (key) that is inserted into the OSPF
header when routing protocol packets are originated by this device.
Assign a separate password to each network for different interfaces.
◆
When using simple password authentication, a password is included in
the packet. If it does not match the password configured on the
receiving router, the packet is discarded. This method provides very
little security as it is possible to learn the authentication key by
snooping on routing protocol packets.
◆
When using Message-Digest 5 (MD5) authentication, the router uses
the MD5 algorithm to verify data integrity by creating a 128-bit
message digest from the authentication key. Without the proper key
and key-id, it is nearly impossible to produce any message that
matches the pre-specified target message digest.
◆
Before specifying plain-text password authentication for an interface,
configure a password with the
command.
Before specifying MD5 authentication for an interface, configure the
message-digest key-id and key with the
command.
