Step 3. Configure the router as a stub router. Command stub-router Remarks By default, the router is not a stub router in any OSPF process. Configuring OSPF authentication You can configure OSPF packet authentication to ensure the security of packet exchanges. After authentication is configured, OSPF only receives packets that pass authentication. Failed packets cannot establish neighboring relationships. To configure OSPF authentication, you must configure the same area authentication mode on all the routers in the area. In addition, the authentication mode and password for all interfaces attached to the same area must be identical. To configure OSPF authentication: Step 1. Enter system view. 2. Enter OSPF view. 3. Enter area view. 4. Configure the authentication mode. 5. Return to OSPF view. 6. Return to system view. 7. Enter interface view. 8. Configure interface authentication mode.

You can enable an interface to add its MTU into DD packets. To add the interface MTU into DD packets: Step 1. Enter system view. 2. Enter interface view.
