ospfctl — control the Open Shortest Path First daemon


ospfctl [−s socket] command [argument ...]


The ospfctl program controls the ospfd(8) daemon.

The following options are available:

−s socket

Use socket instead of the default /var/run/ospfd.sock to communicate with ospfd(8).

The following commands are available:

fib couple

Insert the learned routes into the Forwarding Information Base a.k.a. the kernel routing table.

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.
