Configuration procedure
1. Configure Router A:
<RouterA> system-view
[RouterA] ipv6
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] ipv6 address fe80::1 link-local
[RouterA-Ethernet1/1] ipv6 address 1::1 64
# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.
[RouterA-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterA-Ethernet1/1] 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-Ethernet1/1] vrrp ipv6 vrid 1 priority 110
# Configure Router A to operate in preemptive mode so that it can become the master whenever
it works correctly; configure the preemption delay as 5 seconds to avoid frequent status
switchover.
[RouterA-Ethernet1/1] vrrp ipv6 vrid 1 preempt-mode timer delay 5
# Enable Router A to send RA messages, so that Host A can learn the default gateway address.
[RouterA-Ethernet1/1] undo ipv6 nd ra halt
2. Configure Router B:
<RouterB> system-view
[RouterB] ipv6
[RouterB] interface ethernet 1/1
[RouterB-Ethernet1/1] ipv6 address fe80::2 link-local
[RouterB-Ethernet1/1] ipv6 address 1::2 64
# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip 1::10
# Configure Router B to operate in preemptive mode, with the preemption delay set to 5 seconds.
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 preempt-mode timer delay 5
