Default OSPF Area#
Underlay Routing → DODefault OSPF Area
Open Shortest Path First, or OSPF, is a routing protocol to exchange IP routes. There are two versions of the OSPF protocol:
- Version 2 is configured on IPv4 interfaces and only exchances IPv4 prefixes
- Version 3 is configured on IPv6 interfaces and exchanges both IPv4 and IPv6 prefixes
Consider using a Fabric
This resource is typically created as a derived resource by the Fabric resource, which takes care of building your entire datacenter fabric, and includes an option to use OSPF in the underlay. Whenever possible, use the Fabric resource instead of manually creating a DefaultOSPFArea.
OSPF sessions in the default VRF are always established between DefaultOSPFInterfaces in a DefaultOSPFArea, and never operate inter-area. To connect two OSPF areas to each other, an area border router (ABR) configures both areas in the same DefaultOSPFInstance. A DefaultOSPFInstance is an isolated process with its own Link State Database (LSDB).
OSPF area notation
In EDA, the area identifier follows the IP-like "Dotted Decimal Notation" to represent a 32-bit integer, meaning area 1 should be entered as 0.0.0.1.
To set up an OSPF area in the overlay, use

-
Area ID. 32-bit in the dotted-quad notation (e.g., "0.0.0.0").
default: "0.0.0.0"format: ipv4 -
Area type. Normal is assumed if not specified.
default: "Normal"enum: "Normal", "Stub", "NSSA"
STATUS
DefaultOSPFAreaStatus defines the observed state of DefaultOSPFArea
-
Indicates the health score of the OSPF area.
-
Indicates the reason for the health score.
-
The time when the state of the resource last changed.
-
The number of active interfaces in the OSPF area.
-
The number of discovered neighbors in the OSPF area.
