The document discusses configuring OSPF routing on multiple routers. It explains that OSPF configuration involves enabling OSPF on each router, defining the interfaces and networks, and verifying neighbor relationships. It then provides an example of configuring a multi-area OSPF network with area 0, area 1, and an area border router connecting the two areas. The configuration involves specifying the area IDs for each router's interfaces to establish neighbors between routers in different areas.
