By default, the router is not
configured as a stub router.
A stub router is not related to a
stub area.
Configuring OSPF authentication
Perform this task to configure OSPF area and interface authentication.
OSPF adds the configured password into sent packets, and uses the password to authenticate
received packets. Only packets that pass the authentication can be received. If a packet fails the
authentication, the OSPF neighbor relationship cannot be established.
If you configure OSPF authentication for both an area and an interface in that area, the interface
uses the OSPF authentication configured on it.
Configuring OSPF area authentication
You must configure the same authentication mode and password on all the routers in an area.
To configure OSPF area authentication:

authentication mode.
• Configure MD5 authentication:

md5 } key-id { cipher | plain }
password
• Configure simple authentication:
authentication-mode simple
{ cipher | plain } password
By default, no
authentication is
configured.
Configuring OSPF interface authentication
