Configuring OSPFv3 route redistribution
Network requirements
• In Figure 204, Router A, LB, and Router B are in Area 2.
• OSPFv3 process 1 and OSPFv3 process 2 are enabled on LB. LB communicates with Router A and
Router B 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
LB, and set the default metric for redistributed routes to 3. Router B can then learn the routes destined
for 1::0/64 and 2::0/64, and Router A cannot learn the routes destined for 3::0/64 or 4::0/64.
