### OSPFv2 Routing
Infix supports OSPF dynamic routing for IPv4, i.e., OSPFv2.

NSSA and Stub areas are currently supported.
#### OSPF area types
In addition to *regular* OSPF areas, area types *NSSA* and *Stub* are supported.

#### OSPF interface settings
We have already seen how to enable OSPF per interface (*enabled true*)
and BFD for OSPF per interface (*bfd enabled true*). These and other
OSPF interface settings are done in context of an OSFP area, e.g.,
*area 0.0.0.0*. Available commands can be listed using the `?` mark.

For example, setting the OSPF *interface type* to *point-to-point* for
an Ethernet interface can be done as follows.
admin@example:/config/routing/control-plane-protocol/ospfv2/name/default/ospf/area/0.0.0.0/interface/e0/> set interface-type point-to-point

#### Debug OSPFv2
Using NETCONF and the YANG model *ietf-routing* it is possible to read the OSPF routing table, neighbors
and more, that may be useful for debugging the OSPFv2 setup.
and more, that may be useful for debugging the OSPFv2 setup. The CLI
has various OSPF status commands such as `show ospf neighbor`, `show
ospf interface` and `show ospf routes`.
