The output shows that when LB B fails, LB C becomes the master.

IPv6 VRRP configuration examples

Single VRRP group configuration example

Network requirements

• LB A and LB B belong to VRRP group 1 with the virtual IPv6 addresses of 1::10/64 and FE80::10.

• Host A wants to access Host B on the Internet. Host A learns 1::10/64 as its default gateway through

the RA messages sent by the routers.

• When LB A operates properly, packets sent from Host A to Host B are forwarded by LB A. When LB

A fails, packets sent from Host A to Host B are forwarded by LB B.

Configuration procedure

1. Configure LB A:

<LBA> system-view

[LBA] ipv6

[LBA] interface gigabitethernet0/1

[LBA-GigabitEthernet0/1] ipv6 address fe80::1 link-local

[LBA-GigabitEthernet0/1] ipv6 address 1::1 64

# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.

[LBA-GigabitEthernet0/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local

[LBA-GigabitEthernet0/1] vrrp ipv6 vrid 1 virtual-ip 1::10

# Configure the priority of LB A in VRRP group 1 as 110, which is higher than that of LB B (100),

so that LB A can become the master.

[LBA-GigabitEthernet0/1] vrrp ipv6 vrid 1 priority 110
