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:
Step
1. Enter system view.
2. Enter OSPF view.
3. Enter area view.
4. Configure area authentication
mode.
Configuring OSPF interface authentication
You must configure the same authentication mode and password on both the local interface and its peer
interface.
To configure OSPF interface authentication:
Step
1. Enter system view.
2. Enter interface view.
