.Sh DESCRIPTION
The
.Nm
program controls the
.Xr ospfd 8
daemon.
Commands may be abbreviated to the minimum unambiguous prefix; for example,

The following options are available:
.Bl -tag -width Ds
.It Fl s Ar socket

.Bl -tag -width Ds
.It Cm fib couple
Insert the learned routes into the Forwarding Information Base
a.k.a. the kernel routing table.
.It Cm fib decouple
Remove the learned routes from the Forwarding Information Base
a.k.a. the kernel routing table.
Decoupling the FIB from an OSPF router may create routing loops and could cause
major routing issues in the complete OSPF cloud.
Only routers with just one link to the OSPF cloud can safely decouple the FIB.
.It Cm fib reload
Refetches and relearns the routes in the Forwarding Information Base
a.k.a. the kernel routing table.
.It Cm log brief
Disable verbose debug logging.
.It Cm log verbose
Enable verbose debug logging.
.It Cm reload
