配置VRRP6负载分担示例

组网需求

如图3-25所示，IPv6网络中，HostA和HostC通过Switch双归属到SwitchA和SwitchB。为减轻SwitchA上数据流量的承载压力，HostA以SwitchA为默认网关接入Internet，SwitchB作为其备份网关；HostC以SwitchB为默认网关接入Internet，SwitchA作为其备份网关，以实现流量的负载均衡。

请确保该场景下互联接口的STP处于未使能状态。同时将互连接口退出VLAN1，避免形成环路。因为在使能STP的环形网络中，如果用交换机的VLANIF接口构建三层网络，会导致某个端口被阻塞，从而导致三层业务不能正常运行。

图3-25 配置VRRP6负载分担组网图

设备	接口	对应的Vlanif	IP地址
SwitchA	GE0/0/1	VLANIF300	2002::1/64
SwitchA	GE0/0/2	VLANIF100	FC00::1/64
SwitchB	GE0/0/1	VLANIF200	2001::1/64
SwitchB	GE0/0/2	VLANIF100	FC00::2/64
SwitchC	GE0/0/1	VLANIF300	2002::2/64
	GE0/0/2	VLANIF200	2001::2/64
	GE0/0/3	VLANIF400	2003::2/64

配置思路

采用VRRP6负载分担实现流量的负载均衡，配置思路如下：

配置各设备接口IP地址及路由协议，使网络层连通。
在SwitchA和SwitchB上创建VRRP6备份组1和VRRP6备份组2，在备份组1中，配置SwitchA为Master设备，SwitchB为Backup设备；在备份组2中，配置SwitchB为Master设备，SwitchA为Backup设备，实现流量的负载均衡。

操作步骤

配置设备间的网络互连

# 配置各接口所属VLAN，以SwitchA为例。SwitchB和SwitchC的配置与SwitchA类似，详见配置文件。

<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan batch 100 300
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type hybrid
[SwitchA-GigabitEthernet0/0/1] port hybrid pvid vlan 300
[SwitchA-GigabitEthernet0/0/1] port hybrid untagged vlan 300
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] port link-type hybrid
[SwitchA-GigabitEthernet0/0/2] port hybrid pvid vlan 100
[SwitchA-GigabitEthernet0/0/2] port hybrid untagged vlan 100
[SwitchA-GigabitEthernet0/0/2] quit

# 配置设备各接口的IP地址，以SwitchA为例。SwitchB和SwitchC的配置与SwitchA类似，详见配置文件。

[SwitchA] ipv6
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] ipv6 enable
[SwitchA-Vlanif100] ipv6 address FC00::1 64
[SwitchA-Vlanif100] quit
[SwitchA] interface vlanif 300
[SwitchA-Vlanif300] ipv6 enable
[SwitchA-Vlanif300] ipv6 address 2002::1 64
[SwitchA-Vlanif300] quit

# 配置Switch的二层转发功能。

<HUAWEI> system-view
[HUAWEI] sysname Switch
[Switch] vlan 100
[Switch-vlan100] quit
[Switch] interface gigabitethernet 0/0/1
[Switch-GigabitEthernet0/0/1] port link-type hybrid
[Switch-GigabitEthernet0/0/1] port hybrid pvid vlan 100
[Switch-GigabitEthernet0/0/1] port hybrid untagged vlan 100
[Switch-GigabitEthernet0/0/1] quit
[Switch] interface gigabitethernet 0/0/2
[Switch-GigabitEthernet0/0/2] port link-type hybrid
[Switch-GigabitEthernet0/0/2] port hybrid pvid vlan 100
[Switch-GigabitEthernet0/0/2] port hybrid untagged vlan 100
[Switch-GigabitEthernet0/0/2] quit

# 配置SwitchA、SwitchB和SwitchC间采用OSPFv3协议进行互连。以SwitchA为例，SwitchB和SwitchC的配置与SwitchA类似，详见配置文件。

[SwitchA] ospfv3
[SwitchA-ospfv3-1] router-id 1.1.1.1
[SwitchA-ospfv3-1] quit
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] ospfv3 1 area 0
[SwitchA-Vlanif100] quit
[SwitchA] interface vlanif 300
[SwitchA-Vlanif300] ospfv3 1 area 0
[SwitchA-Vlanif300] quit

配置VRRP6备份组

# 在SwitchA和SwitchB上创建VRRP6备份组1，配置SwitchA的优先级为120，抢占延时为20秒，作为Master设备；SwitchB的优先级为缺省值，作为Backup设备。

[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] vrrp6 vrid 1 virtual-ip FE80::1 link-local
[SwitchA-Vlanif100] vrrp6 vrid 1 virtual-ip FC00::100
[SwitchA-Vlanif100] vrrp6 vrid 1 priority 120
[SwitchA-Vlanif100] vrrp6 vrid 1 preempt-mode timer delay 20
[SwitchA-Vlanif100] quit

[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] vrrp6 vrid 1 virtual-ip FE80::1 link-local
[SwitchB-Vlanif100] vrrp6 vrid 1 virtual-ip FC00::100
[SwitchB-Vlanif100] quit

# 在SwitchA和SwitchB上创建VRRP6备份组2，配置SwitchB的优先级为120，抢占延时为20秒，作为Master设备；SwitchA的优先级为缺省值，作为Backup设备。

[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] vrrp6 vrid 2 virtual-ip FE80::2 link-local
[SwitchB-Vlanif100] vrrp6 vrid 2 virtual-ip FC00::60
[SwitchB-Vlanif100] vrrp6 vrid 2 priority 120
[SwitchB-Vlanif100] vrrp6 vrid 2 preempt-mode timer delay 20
[SwitchB-Vlanif100] quit

[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] vrrp6 vrid 2 virtual-ip FE80::2 link-local
[SwitchA-Vlanif100] vrrp6 vrid 2 virtual-ip FC00::60
[SwitchA-Vlanif100] quit

# 完成上述配置后，在SwitchA上执行display vrrp6命令，可以看到SwitchA在备份组1中作为Master设备，在备份组2中作为Backup设备。
