本举例是在M9000-AI-E8的R9071版本上进行配置和验证的。
如下图所示，某公司以Device作为网络边界安全防护设备，连接公司内部网络和Internet。为提高业务稳定性，使用两台Device进行HA组网，Device A作为主设备，Device B作为备设备。当Device A或其链路发生故障时，由Device B接替Device A继续工作，保证业务不中断。
图-1 HA联动VRRP三层直连主备组网图（IPv6应用）
仅支持两台设备进行HA组网。
因为一台设备故障时另一台设备需要承担两台设备的流量，所以建议在正常情况下每台设备只负载各自实际能力50%的流量。
部署HA前，请先保证主/备设备硬件环境的一致性，具体要求如下：
主/备设备的型号必须一致。
主/备设备主控板的位置、数量和类型必须一致。
主/备设备业务板的位置、数量和类型必须一致。
主/备设备交换网板的位置、数量和类型必须一致。
主/备设备接口板的位置、数量和类型必须一致。
主/备设备上管理接口、业务接口、HA通道接口需要分别使用相互独立的接口，且所使用的接口编号和类型必须一致。
主/备设备上硬盘的位置、数量和类型建议一致。未安装硬盘的设备日志存储量将远低于安装了硬盘的设备，而且部分日志和报表功能不可用。
部署HA前，请先保证主/备设备软件环境的一致性，具体要求如下：
主/备设备的系统软件环境及其版本必须一致，如：Boot包、System包、Feature包和补丁包等等。
主/备设备上被授权的特征库和特性环境必须一致，如：特征库的种类，每类特征库的版本、授权时间范围、授权的资源数等等。
主/备设备的接口编号必须一致。
主/备设备之间建立HA通道的接口类型、速率和编号等信息必须一致，推荐使用聚合接口。
主/备设备上聚合接口的编号、成员接口编号必须一致。
主/备设备相同位置的接口必须加入到相同的安全域。
主/备设备的HASH选择CPU模式以及HASH因子都必须相同（即forwarding policy命令）。
配置接口IPv6地址
# 根据组网图中规划的信息，配置各接口的IPv6地址，具体配置步骤如下。
<Router> system-view
[Router] interface gigabitethernet 1/0/7
[Router-GigabitEthernet1/0/7] ipv6 address 3003::15/64
[Router-GigabitEthernet1/0/7] quit
请参考以上步骤配置其他接口的IP地址，具体配置步骤略。
配置静态路由，保证网络路由可达
本举例仅以静态路由方式配置路由信息。实际组网中，请根据具体情况选择相应的路由配置方式。
# 请根据组网图中规划的信息，配置静态路由。本举例假设去往内网流量的下一跳IPv6地址为VRRP备份组1的虚拟IPv6地址3003::3/64，去往Internet流量的下一跳IPv6地址为3007::15/64，实际环境中请以具体组网情况为准，具体配置步骤如下。
[Router] ipv6 route-static 3001::3 64 3003::3
[Router] ipv6 route-static 0::0 64 3007::15
在Switch A上创建VLAN 10，并将连接Device A、Device B和Router的接口链路类型设置为Access，并将接口加入VLAN 10。
# 根据组网图中规划的信息，配置各接口加入VLAN，并设置链路类型，具体配置步骤如下。
<SwitchA> system-view

[SwitchA-vlan10] quit
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] port access vlan 10
[SwitchA-GigabitEthernet1/0/1] quit
[SwitchA] interface gigabitethernet 1/0/2
[SwitchA-GigabitEthernet1/0/2] port access vlan 10
[SwitchA-GigabitEthernet1/0/2] quit
[SwitchA] interface gigabitethernet 1/0/3
[SwitchA-GigabitEthernet1/0/3] port access vlan 10
[SwitchA-GigabitEthernet1/0/3] quit
# 在Switch B上创建VLAN 10，并将连接Device A、Device B和Host的接口设置成工作在二层模式，接口链路类型为Access，并将此接口加入VLAN 10。
# 根据组网图中规划的信息，配置各接口加入VLAN，并设置链路类型，具体配置步骤如下。
<SwitchB> system-view
[SwitchB] vlan 10
[SwitchB-vlan10] quit
[SwitchB] interface gigabitethernet 1/0/1
[SwitchB-GigabitEthernet1/0/1] port access vlan 10
[SwitchB-GigabitEthernet1/0/1] quit
[SwitchB] interface gigabitethernet 1/0/2
[SwitchB-GigabitEthernet1/0/2] port access vlan 10
[SwitchB-GigabitEthernet1/0/2] quit
