Procedure
Step 1 Configure the devices to ensure network connectivity. For configuration details, see the
configuration file of this example.
Assign 2001:db8::100 to a default gateway used by host A.
Step 2 Configure OSPFv3 on Router A, Router B, and Router C. For configuration details, see the
configuration file of this example.
Step 3 Configure a VRRP IPv6 backup group.
# Assign an IPv6 address to GE 1/0/0 on Router A; create VRRP IPv6 backup group 1 on GE
1/0/0; set the VRRP priority to 120 so that Router A is the Master.
<HUAWEI> system-view
[HUAWEI] sysname RouterA
[RouterA] ipv6
[RouterA] interface gigabitethernet 1/0/0
[RouterA-GigabitEthernet1/0/0] undo shutdown
[RouterA-GigabitEthernet1/0/0] ipv6 enable
[RouterA-GigabitEthernet1/0/0] ipv6 address 2001:db8::1 64

[RouterA-GigabitEthernet1/0/0] vrrp6 vrid 1 priority 120
[RouterA-GigabitEthernet1/0/0] vrrp6 vrid 1 preempt-mode timer delay 20
[RouterA-GigabitEthernet1/0/0] quit
# Assign an IPv6 address to GE 1/0/0 on Router B; create VRRP IPv6 backup group 1 on GE
1/0/0, in which Router B is the backup.
<HUAWEI> system-view
[HUAWEI] sysname RouterB
[RouterB] ipv6
[RouterB] interface gigabitethernet 1/0/0
[RouterB-GigabitEthernet1/0/0] undo shutdown
[RouterB-GigabitEthernet1/0/0] ipv6 enable
[RouterB-GigabitEthernet1/0/0] ipv6 address 2001:db8::2 64

Issue 02 (2014-09-30)
IP address of each interface on each device (For details, see configuration files.)
VRRP priority of each router in the VRRP IPv6 backup group
VRID (1) and virtual IPv6 address (2001:db8::100) for the VRRP IPv6 backup group
configured on Router A and Router B
VRRP priorities (120 for Router A and 100 for Router B)
Local and remote discriminators of a peer BFD session
Value (40) by which Router B increases its VRRP priority and triggers a master/backup
VRRP switchover if its tracked BFD session goes Down
Value (40) by which Router A reduces its VRRP priority and triggers a master/backup
VRRP switchover if its tracked interface goes Down
Preemption delay (20s)
