Verifying the configuration
After all switches function properly, perform a master/backup switchover on Switch A to trigger an
OSPFv3 GR operation.
Configuring BFD for OSPFv3
Network requirements
As shown in Figure 80:
• Configure OSPFv3 on Switch A, Switch B and Switch C and configure BFD over the link Switch
A<—>L2 Switch<—>Switch B.
• After the link Switch A<—>L2 Switch<—>Switch B fails, BFD can quickly detect the failure and
notify OSPFv3 of the failure. Then Switch A and Switch B communicate through Switch C.

Device Interface IPv6 address
Switch A Vlan-int10 2001::1/64 Switch B Vlan-int10 2001::2/64
Vlan-int11 2001:2::1/64
Switch C Vlan-int11 2001:2::2/64
Vlan-int13 2001:3::1/64
Configuration procedure
1. Configure IP addresses for the interfaces. (Details not shown.)
2. Configure basic OSPFv3:
# On Switch A, enable OSPFv3 and specify the router ID as 1.1.1.1.
<SwitchA> system-view
[SwitchA] ospfv3
[SwitchA-ospfv3-1] router-id 1.1.1.1
[SwitchA-ospfv3-1] quit
[SwitchA] interface vlan-interface 10
[SwitchA-Vlan-interface10] ospfv3 1 area 0
[SwitchA-Vlan-interface10] quit
[SwitchA] interface vlan-interface 11
[SwitchA-Vlan-interface11] ospfv3 1 area 0
[SwitchA-Vlan-interface11] quit
# On Switch B, enable OSPFv3 and specify the router ID as 2.2.2.2.
