Overview YANG [RFC6020] is a data definition language that was introduced to define the contents of a conceptual data store that allows networked devices to be managed using NETCONF [RFC6241]. YANG is proving relevant beyond its initial confines, as bindings to other interfaces (e.g. ReST) and encodings other than XML (e.g. JSON) are being defined. Furthermore, YANG data models can be used as the basis of implementation for other interfaces, such as CLI and programmatic @@ -137,32 +139,42 @@ +--rw routing-protocol [name] +--rw ospf . . +--rw all-instances-inherit {instance-inheritance}? | . | . +--rw instance* [routing-instance af] . . - +--rw all-areas-inherit {area-inheritance}? - | . - | . - +--rw area* [area-id] + +--rw areas + | +--rw area* [area-id] | . | . | +--rw all-interfaces-inherit {interface-inheritance}? | . | . - | +--rw interface* [interface] + | +--rw virtual-links + | | +--rw virtual-link* [router-id] + | | . + | | . + | +--rw sham-links + | | +--rw sham-link* [local-id remote-id] + | | . + | | . + | +--rw interfaces + | | +--rw interface* [interface] + | | . + | | . | . | . + +--rw topologies +--rw topology* [name] The ospf is intended to match to the vendor specific OSPF configuration construct which is identified by a local identifier 'name'.
