Configuration procedure
1. Configure Router A:
system-view
[RouterA] ipv6
[RouterA] interface ethernet 1/2
[RouterA-Ethernet1/2] ipv6 address fe80::1 link-local
[RouterA-Ethernet1/2] ipv6 address 1::1 64
# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.
[RouterA-Ethernet1/2] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterA-Ethernet1/2] vrrp ipv6 vrid 1 virtual-ip 1::10
# Configure the priority of Router A in VRRP group 1 as 110, which is higher than that of Router
B (100), so that Router A can become the master.
[RouterA-Ethernet1/2] vrrp ipv6 vrid 1 priority 110
# Set the authentication mode of VRRP group 1 as simple and authentication key to hello.
[RouterA-Ethernet1/2] vrrp ipv6 vrid 1 authentication-mode simple hello
# Set the interval on Router A for sending VRRP advertisements to 400 centiseconds.
[RouterA-Ethernet1/2] vrrp ipv6 vrid 1 timer advertise 400
# Configure Router A to operate in preemptive mode, so that it can become the master whenever
it works correctly. Set the preemption delay to 5 seconds to avoid frequent status switchover.
[RouterA-Ethernet1/2] vrrp ipv6 vrid 1 preempt-mode timer delay 5
# Set Ethernet 1/1 on Router A to be tracked, and configure the amount by which the priority value
decreases to be more than 10 (30 in this example), so that when Ethernet 1/1 fails, the priority of
Router A in VRRP group 1 decreases to a value lower than 100 and thus Router B can become the
master.
[RouterA-Ethernet1/2] vrrp ipv6 vrid 1 track interface ethernet 1/1 reduced 30
# Enable Router A to send RA messages, so that Host A can learn the default gateway address.
[RouterA-Ethernet1/2] undo ipv6 nd ra halt
2. Configure Router B:
system-view
[RouterB] ipv6
