Fig 2-2 VRRPv3 Typical Network Topology
As shown in graph, switch A and switch B are backups to each other, switch A is
the master of backup group 1 and a backup of backup group 2. Switch B is the mast
er of backup group 2 and a Backup of backup group 1. The IPv6 addresses of switch
A and switch B are “IPv6_A” and “IPv6_ B” respectively (it is recommended that IPv6_
A and IPv6_B are in the same segment), the virtual IPv6 address of backup group 1 a
nd backup group are “V_IPv6_C” and “V_IPV6_D” respectively, and the default IPv6 gat
eway 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 advertisemen
ts, thus, the IPv6 next hop of the hosts will have some randomness). Doing this will n
ot only implement router backup but also the flow sharing function in the LAN.
The configuration of SwitchA:
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
