Configuration procedure
1. Configure Router A:
# Configure VRRP to operate in load balancing mode.
system-view
[RouterA] vrrp ipv6 mode load-balance
# Create VRRP group 1, and set its virtual IPv6 addresses to FE80::10 and 1::10.
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] ipv6 address fe80::1 link-local
[RouterA-Ethernet1/1] ipv6 address 1::1 64
[RouterA-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterA-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip 1::10
# Assign Router A the highest priority in VRRP group 1, so Router A can become the master.
[RouterA-Ethernet1/1] vrrp ipv6 vrid 1 priority 120
# Configure Router A to operate in preemptive mode, so it can become the master whenever it
operates correctly. Set the preemption delay to 5 seconds to avoid frequent status switchover.
[RouterA-Ethernet1/1] vrrp ipv6 vrid 1 preempt-mode delay 5
# Enable Router A to send RA messages, so hosts on subnet 1::/64 can learn the default gateway
address.
[RouterA-Ethernet1/1] undo ipv6 nd ra halt
[RouterA-Ethernet1/1] quit
# Create track entry 1 to monitor the upstream link status of Ethernet 1/2. When the upstream link
fails, the track entry transits to Negative.
[RouterA] track 1 interface ethernet 1/2
# Configure the VFs in VRRP group 1 to monitor track entry 1, and decrease their weights by 250
when the track entry transits to Negative.
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] vrrp ipv6 vrid 1 weight track 1 reduced 250
2. Configure Router B:
# Configure VRRP to operate in load balancing mode.
system-view
[RouterB] vrrp ipv6 mode load-balance
# Create VRRP group 1, and set its virtual IPv6 addresses to FE80::10 and 1::10.
[RouterB] interface ethernet 1/1
[RouterB-Ethernet1/1] ipv6 address fe80::2 link-local
[RouterB-Ethernet1/1] ipv6 address 1::2 64
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip 1::10
# Assign Router B a higher priority than Router C in VRRP group 1, so Router B can become the
master when Router A fails.
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 priority 110
# Configure Router B to operate in preemptive mode and set the preemption delay to 5 seconds.
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 preempt-mode delay 5
# Enable Router B to send RA messages, so hosts on subnet 1::/64 can learn the default gateway
address.
[RouterB-Ethernet1/1] undo ipv6 nd ra halt
