RemarksConfigure theauthentication mode ofthe OSPF interfaceospfauthentication-mode{ simple password | md5key-id key }RequiredBy default, OSPF packetsare not authenticated onan interface.Note:z OSPF supports packet authentication and receives only those packets that aresuccessfully authenticated. If packet authentication fails, no neighboringrelationship will be established.z The authentication modes for all routers in an area must be consistent. Theauthentication passwords for all routers on a network segment must also beconsistent.4.7.7 Configuring to Fill the MTU Field When an Interface Transmits DDPacketsBy default, an interface uses value 0 instead of its actual MTU value whentransmitting DD packets. After the following configuration, the actual MTU value of theinterface is filled in the Interface MTU field of the DD packets.Follow these steps to configure the MTU field to be filled when an interface transmitsDD packetsTo do...
