OSPFv3 route redistribution configuration example
Network requirements
As shown in Figure 81:
Switch A, Switch B, and Switch C are in Area 2.
OSPFv3 process 1 and OSPFv3 process 2 run 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. Switch C can then 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.

Configuration procedure
Configure IPv6 addresses for interfaces. (Details not shown.)
Configure basic OSPFv3:
# Enable OSPFv3 process 1 on Switch A.
<SwitchA> system-view [SwitchA] ospfv3 1 [SwitchA-ospfv3-1] router-id 1.1.1.1 [SwitchA-ospfv3-1] quit [SwitchA] interface vlan-interface 100 [SwitchA-Vlan-interface100] ospfv3 1 area 2 [SwitchA-Vlan-interface100] quit [SwitchA] interface vlan-interface 200 [SwitchA-Vlan-interface200] ospfv3 1 area 2 [SwitchA-Vlan-interface200] quit
# Enable OSPFv3 process 1 and OSPFv3 process 2 on Switch B.
<SwitchB> system-view [SwitchB] ospfv3 1 [SwitchB-ospfv3-1] router-id 2.2.2.2 [SwitchB-ospfv3-1] quit [SwitchB] interface vlan-interface 100 [SwitchB-Vlan-interface100] ospfv3 1 area 2 [SwitchB-Vlan-interface100] quit [SwitchB] ospfv3 2 [SwitchB-ospfv3-2] router-id 3.3.3.3 [SwitchB-ospfv3-2] quit [SwitchB] interface vlan-interface 300 [SwitchB-Vlan-interface300] ospfv3 2 area 2 [SwitchB-Vlan-interface300] quit
# Enable OSPFv3 process 2 on Switch C.
<SwitchC> system-view [SwitchC] ospfv3 2 [SwitchC-ospfv3-2] router-id 4.4.4.4 [SwitchC-ospfv3-2] quit [SwitchC] interface vlan-interface 300 [SwitchC-Vlan-interface300] ospfv3 2 area 2 [SwitchC-Vlan-interface300] quit [SwitchC] interface vlan-interface 400 [SwitchC-Vlan-interface400] ospfv3 2 area 2 [SwitchC-Vlan-interface400] quit

Configure OSPFv3 route redistribution:
# Configure OSPFv3 process 2 to redistribute direct routes and the routes from OSPFv3 process 1 on Switch B.
[SwitchB] ospfv3 2 [SwitchB-ospfv3-2] default cost 3 [SwitchB-ospfv3-2] import-route ospfv3 1 [SwitchB-ospfv3-2] import-route direct [SwitchB-ospfv3-2] quit
# Display the routing table on Switch C.
