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.
