IPv6_A and IPv6_B are in the same segment), the virtual IPv6 address of backup group 1 and backup group

are “V_IPv6_C” and “V_IPV6_D” respectively, and the default IPv6 gateway address are configured as

“V_IPv6_C” and “V_IPv6_D” respectively (in reality, the IPv6 gateway address of hosts are usually learnt

automatically via router advertisements, thus, the IPv6 next hop of the hosts will have some randomness).

Doing this will not only implement router backup but also the flow sharing function in the LAN.

The configuration of SwitchA:

SwitchA (config)#ipv6 enable

SwitchA (config)#interface vlan 1

SwitchA (config)#router ipv6 vrrp 1

SwitchA (config-router)#virtual-ipv6 fe80::2 interface vlan 1

SwitchA (config-router)#priority 150

SwitchA (config-router)#enable

SwitchA (config)#router ipv6 vrrp 2

SwitchA (config-router)#virtual-ipv6 fe80::3 interface vlan 1

SwitchA (config-router)#enable

The configuration of SwitchB:

SwitchB (config)# ipv6 enable

SwitchB (config)# interface vlan 1

SwitchB (config)# router ipv6 vrrp 2

SwitchB (config-router)# virtual-ipv6 fe80::3 interface vlan 1

SwitchB (config-router)# priority 150

SwitchB (config-router)# enable

SwitchB (config)# router ipv6 vrrp 1

SwitchB (config-router)# virtual-ipv6 fe80::2 interface vlan 1

SwitchB (config-router)# enable

65.4 VRRPv3 Troubleshooting

When configuring and using VRRPv3 protocol, it might operate abnormally because of incorrect physical

connections and configuration. So, users should pay attention to the following points:

 First, the physical connections should be correct;

 Next, the interface and link protocol are UP (use show ipv6 interface command);

 And then, make sure that IPv6 forwarding function is enabled (use ipv6 enable command);

 Besides, make sure that VRRPv3 protocol is enable on the interface;

 Check whether the time of timer in different routers (or layer-three Ethernet switch) within the same

backup group is the same;

 Check whether the virtual IPv6 addresses in the same backup group is the same.
