配置思路
采用VRRP主备备份实现网关冗余备份,配置思路如下: 1、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。 2、在SwitchA和SwitchB上配置VRRP备份组。其中: SwitchA上配置较高优先级和20秒抢占延时,作为Master设备承担流量转发; SwitchB上配置较低优先级,作为备用交换机,实现网关冗余备份。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,详见配置文件。
<HUAWEI> system-view [HUAWEI] sysname SwitchA [SwitchA] vlan batch 100 300 [SwitchA] interface gigabitethernet 1/0/1 [SwitchA-GigabitEthernet1/0/1] port link-type hybrid [SwitchA-GigabitEthernet1/0/1] port hybrid pvid vlan 300 [SwitchA-GigabitEthernet1/0/1] port hybrid untagged vlan 300 [SwitchA-GigabitEthernet1/0/1] quit [SwitchA] interface gigabitethernet 1/0/2 [SwitchA-GigabitEthernet1/0/2] port link-type hybrid [SwitchA-GigabitEthernet1/0/2] port hybrid pvid vlan 100 [SwitchA-GigabitEthernet1/0/2] port hybrid untagged vlan 100 [SwitchA-GigabitEthernet1/0/2] quit [SwitchA] interface vlanif 100 [SwitchA-Vlanif100] ip address 10.1.1.1 24 [SwitchA-Vlanif100] quit [SwitchA] interface vlanif 300 [SwitchA-Vlanif300] ip address 192.168.1.1 24 [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 1/0/1 [Switch-GigabitEthernet1/0/1] port link-type hybrid [Switch-GigabitEthernet1/0/1] port hybrid pvid vlan 100 [Switch-GigabitEthernet1/0/1] port hybrid untagged vlan 100 [Switch-GigabitEthernet1/0/1] quit [Switch] interface gigabitethernet 1/0/2 [Switch-GigabitEthernet1/0/2] port link-type hybrid [Switch-GigabitEthernet1/0/2] port hybrid pvid vlan 100 [Switch-GigabitEthernet1/0/2] port hybrid untagged vlan 100 [Switch-GigabitEthernet1/0/2] quit
# 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,详见配置文件。
[SwitchA] ospf 1 [SwitchA-ospf-1] area 0 [SwitchA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255 [SwitchA-ospf-1-area-0.0.0.0] network 192.168.1.0 0.0.0.255 [SwitchA-ospf-1-area-0.0.0.0] quit [SwitchA-ospf-1] quit
- 配置VRRP备份组
# 在SwitchA上创建VRRP备份组1,配置SwitchA在该备份组中的优先级为120,并配置抢占时间为20秒。
[SwitchA] interface vlanif 100 [SwitchA-Vlanif100] vrrp vrid 1 virtual-ip 10.1.1.111 [SwitchA-Vlanif100] vrrp vrid 1 priority 120 //设备在VRRP备份组中的优先级缺省为100,修改Master设备的优先级大于Backup设备 [SwitchA-Vlanif100] vrrp vrid 1 preempt-mode timer delay 20 //设备在VRRP备份组中缺省采用立即抢占方式。修改Master设备的延迟抢占时间,以避免在网络环境不稳定时,由于双方频繁抢占而导致流量中断的问题 [SwitchA-Vlanif100] quit
# 在SwitchB上创建VRRP备份组1,其在该备份组中的优先级采用缺省值100(不需要配置)。
[SwitchB] interface vlanif 100 [SwitchB-Vlanif100] vrrp vrid 1 virtual-ip 10.1.1.111 [SwitchB-Vlanif100] quit
- 验证配置结果
# 完成上述配置以后,在SwitchA和SwitchB上分别执行display vrrp命令,可以看到SwitchA在备份组中的状态为Master,SwitchB在备份组中的状态为Backup。
