Ospfv2

simple module

Implements the OSPFv2 routing protocol.

The ospfConfig parameter can specify an XML file describing the configuration of all OSPF routers and their interfaces in the network.

The XML configuration must contain exactly one <OSPFASConfig> root element which describes an OSPF autonomous system with its areas and its routers. The Area IDs, Router IDs and area Address Ranges must be unique within the autonomous system. Various OSPF parameters can be specified for the network interfaces in the XML file. If those parameters are not specified in the XML file, the module parameters of the OSPF module are used instead.

<Area> - defines an area in the network.
@id - Mandatory attribute containing the area ID in dotted decimal notation. The backbone is '0.0.0.0'. (NOTE: This is not an IP address though it looks like one.)
<AddressRange> - Describes an address range of an OSPF area.

@address - A string which is resolvable by IPvXAddressResolver class. (e.g. Area1.R1>Area1.N1)
@mask - A string which is resolvable by IPvXAddressResolver class. (e.g. Area1.R1>Area1.N1)
@status - Decides whether an address range will be advertised in Summary LSAs. (Advertise or DoNotAdvertise)

<Stub> - Any OSPF area (except the backbone) can be configured as a stub area.

@defaultCost - A required attribute that defines the default route cost (>=0 and <1000) advertised for the area.

<Router> - Describes an OSPF router with its interfaces. Interface 'ifName' and 'toward' values must be unique within the same router and only one of them must be specified. A router is identified by its Router ID, which is given as an IPv4 address (but isn't necessarily one). It may contain various child elements.

@RFC1583Compatible - optional true or false value (defined in RFC 3101)
@DistributeDefaultRoute - optional true or false value (distribute the default route, if exists, using AS-External LSA)
