Changing OSPF Session Parameters

Configure BFD sessions with default intervals and a default role.

The parameters that you can configure are: desired tx interval, required min rx interval, detection multiplier, and system role. Configure these parameters for all OSPF sessions or all OSPF sessions on a particular interface. If you change a parameter globally, the change affects all OSPF neighbors sessions. If you change a parameter at the interface level, the change affects all OSPF sessions on that interface.

To change parameters for all OSPF sessions or for OSPF sessions on a single interface, use the following commands.

  • Change parameters for OSPF sessions.
    ROUTER-OSPF mode
    bfd all-neighbors interval milliseconds min_rx milliseconds multiplier value role [active | passive]
  • Change parameters for all OSPF sessions on an interface.
    INTERFACE mode
    ip ospf bfd all-neighbors interval milliseconds min_rx milliseconds multiplier value role [active | passive]

To view session parameters, use the show bfd neighbors detail command.
