> OSPF VRF Configuration Mode Commands
> The OSPF VRF Configuration sub-mode is used to configure the virtual routing and forwarding (VRF) context instances for OSPF routing protocol. This mode includes commands that configure VRF instance for OSPF routing parameters.
> Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
