Configuring OSPFv3 route redistribution
Network requirements
• As shown in Figure 99, Router A, Router B, and Router C are in Area 2.
• OSPFv3 process 1 and OSPFv3 process 2 are enabled on Router B. Router B communicates with
Router A and Router C through OSPFv3 process 1 and OSPFv3 process 2, respectively.
• Configure OSPFv3 process 2 to redistribute direct routes and the routes from OSPFv3 process 1 on
Router B, and set the default metric for redistributed routes to 3. Router C can then learn the routes
