Changing OSPF Session Parameters
Congure BFD sessions with default intervals and a default role.
The parameters that you can congure are: desired tx interval, required min rx interval, detection multiplier,
and system role. Congure these parameters for all OSPF sessions or all OSPF sessions on a particular interface. If you change a
parameter globally, the change aects all OSPF neighbors sessions. If you change a parameter at the interface level, the change aects 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.
