Configuring OSPFv3 route redistribution
Network requirements
As shown in Figure 108:
• Switch A, Switch B, and Switch C are in Area 2.
• OSPFv3 process 1 and OSPFv3 process 2 are enabled on Switch B. Switch B communicates with
Switch A and Switch C through OSPFv3 process 1 and OSPFv3 process 2.
Configure OSPFv3 process 2 to redistribute direct routes and the routes from OSPFv3 process 1 on
Switch B and set the default metric for redistributed routes to 3. Then, Switch C can learn the routes
destined for 1::0/64 and 2::0/64, and Switch A cannot learn the routes destined for 3::0/64 or
4::0/64.
