本文主要是介绍华为配置VRRP负载分担示例,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
组网需求
如图1所示,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作为备份网关;HostC以SwitchB为默认网关接入Internet,SwitchA作为备份网关,以实现流量的负载均衡。
说明
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。
配置思路
采用VRRP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,使各设备间网络层连通。
- 在SwitchA和SwitchB上创建VRRP备份组1和VRRP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
# 配置设备各接口的IP地址,以SwitchA为例。SwitchB和SwitchC的配置与SwitchA类似
[zhonwanghzhi]interface GigabitEthernet 0/0/1
[zhonwanghzhi-GigabitEthernet0/0/1]port link-type hybrid
[zhonwanghzhi-GigabitEthernet0/0/1]port hybrid pvid vlan 300
[zhonwanghzhi-GigabitEthernet0/0/1]port hybrid untagged vlan 300
[zhonwanghzhi-GigabitEthernet0/0/1]quit
[zhonwanghzhi]interface GigabitEthernet 0/0/2
[zhonwanghzhi-GigabitEthernet0/0/2]port link-type
[zhonwanghzhi-port-group-link-type]quit
[zhonwanghzhi]interface GigabitEthernet 0/0/2
[zhonwanghzhi-GigabitEthernet0/0/2]port link-type hybrid
[zhonwanghzhi-GigabitEthernet0/0/2]port hybrid pvid vlan 100
[zhonwanghzhi-GigabitEthernet0/0/2]port hybrid untagged vlan 100
[zhonwanghzhi-GigabitEthernet0/0/2]quit
[zhonwanghzhi]
[zhonwanghzhi]interface Vlanif 100
[zhonwanghzhi-Vlanif100]ip address 10.1.1.1 24
[zhonwanghzhi-Vlanif100]quit
[zhonwanghzhi]interface Vlanif 300
[zhonwanghzhi-Vlanif300]ip address 192.168.1.1 24
[zhonwanghzhi-Vlanif300]quit
[zhonwanghzhi]
# 配置Switch的二层转发功能。
[zhongwanzhi]interface GigabitEthernet 0/0/1
[zhongwanzhi-GigabitEthernet0/0/1]port link-type hybrid
[zhongwanzhi-GigabitEthernet0/0/1]port hybrid pvid vlan 100
[zhongwanzhi-GigabitEthernet0/0/1]port hybrid untagged vlan 100
[zhongwanzhi-GigabitEthernet0/0/1]quit
[zhongwanzhi]interface GigabitEthernet 0/0/2
[zhongwanzhi-GigabitEthernet0/0/2]port link-type hybrid
[zhongwanzhi-GigabitEthernet0/0/2]port hybrid pvid vlan 100
[zhongwanzhi-GigabitEthernet0/0/2]port hybrid untagged vlan 100
[zhongwanzhi-GigabitEthernet0/0/2]quit
[zhongwanzhi]
# 配置SwitchA、SwitchB和SwitchC间采用OSPF协议进行互连。以SwitchA为例,SwitchB和SwitchC的配置与SwitchA类似
[zhonwanghzhi]ospf 1
[zhonwanghzhi-ospf-1]area 0
[zhonwanghzhi-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
[zhonwanghzhi-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
[zhonwanghzhi-ospf-1-area-0.0.0.0]quit
[zhonwanghzhi-ospf-1]quit
配置VRRP备份组
# 在SwitchA和SwitchB上创建VRRP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
[zhongwanzhi]interface Vlanif 100
[zhongwanzhi-Vlanif100]vrrp vrid 1 virtual-ip 10.1.1.111
[zhongwanzhi-Vlanif100]vrrp vrid 1 priority 120
[zhongwanzhi-Vlanif100]vrrp vrid 1 preempt-mode timer delay 20
[zhongwanzhi-Vlanif100]quit
SwitchB
[zhonwanghzhib]interface Vlanif 100
[zhonwanghzhib-Vlanif100]vrrp vrid 1 virtual-ip 10.1.1.111
[zhonwanghzhib-Vlanif100]quit
# 在SwitchA和SwitchB上创建VRRP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。
SwitchA
[zhonwanghzhi]interface Vlanif 100
[zhonwanghzhi-Vlanif100]vrrp vrid 2 virtual-ip 10.1.1.112
[zhonwanghzhi-Vlanif100]vrrp vrid 2 priority 120
[zhonwanghzhi-Vlanif100]vrrp vrid 2 preempt-mode timer delay 20
[zhonwanghzhi-Vlanif100]quit
SwitchB
[zhonwanghzhib]interface Vlanif 100
[zhonwanghzhib-Vlanif100]vrrp vrid 1 virtual-ip 10.1.2.112
[zhonwanghzhib-Vlanif100]quit
验证配置结果
# 完成上述配置后,在SwitchA上执行display vrrp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。
