Final answer:
To enable OSPF routing, a network administrator configures OSPF on the router, defining areas and advertising networks to establish efficient communication paths.
Step-by-step explanation:
The task '7.2.7 Enable OSPF Routing' is associated with configuring a network to use the Open Shortest Path First (OSPF) routing protocol. This action is part of network configuration and management. To enable OSPF routing on a network device, such as a router, the administrator must access the device's configuration mode, usually through a command-line interface (CLI), and then issue the specific commands to start the OSPF process, define the OSPF area, and advertise the necessary networks through the OSPF protocol. This is a key step in ensuring that routers can communicate effectively and that data can take the shortest path through an internetwork.
