Configuration Examples for Implementing OSPF
This section provides the following configuration examples:

Cisco IOS XR Software for OSPF Version 2 Configuration: Example

The following example shows how an OSPF interface is configured for an area in Cisco IOS XR Software.
area 0 must be explicitly configured with the area command and all interfaces that are in the range from
10.1.2.0 to 10.1.2.255 are bound to area 0. Interfaces are configured with the interface command (while the
router is in area configuration mode) and the area keyword is not included in the interface statement.

The following example shows how OSPF interface parameters are configured for an area in Cisco IOS XR
software.
In Cisco IOS XR software, OSPF interface-specific parameters are configured in interface configuration mode
and explicitly defined for area 0. In addition, the ip ospf keywords are no longer required.
