Sw21:
[Sw21]vlan batch 10 20 30 40
[Sw21]interface gigabitethernet 0/0/1
[Sw21-GigabitEthernet0/0/1]undo shutdown
[Sw21-GigabitEthernet0/0/1]port link-type access
[Sw21-GigabitEthernet0/0/1]port def vlan 10
Sw1的0/0/2 0/0/3 0/0/4端口都如此分别加入vlan 20 vlan 30 vlan 40
交换机之间配置trunk链路:
[Sw21-GigabitEthernet0/0/5]port link-type trunk
[Sw21-GigabitEthernet0/0/5]port trunk allow-pass vlan all
Sw21的0/0/5 0/0/6 sw18 Gw19 Gw20 的0/0/1 0/0/2 端口全部配置trunk链路
Gw19:
Vlan 10 : [Gw19]in vlan 10
[Gw19-Vlanif10]vrrp vrid 10 virtual-ip 192.168.10.250
[Gw19-Vlanif10]vrrp vrid 10 priority 150(配置优先级)
Vlan20: [Gw19]in vlan 20
[Gw19-Vlanif20]vrrp vrid 20 virtual-ip 192.168.20.250(虚拟ip)
[Gw19-Vlanif20]vrrp vrid 20 priority 150
Vlan30: [Gw19]in vlan 30
[Gw19-Vlanif30]vrrp vrid 30 virtual-ip 192.168.30.250
Vlan40: [Gw19]in vlan 40
[Gw19-Vlanif40]vrrp vrid 40 virtual-ip 192.168.40.250
vlan 30与vlan 40 为默认优先级100
Gw20:
vlan10: [Gw20]in vlan 10
[Gw20-Vlanif10]vrrp vrid 30 virtual-ip 192.168.10.250
Vlan20: [Gw19]in vlan 20
[Gw20-Vlanif20]vrrp vrid 40 virtual-ip 192.168.20.250
Vlan30: [Gw20]in vlan 30
[Gw20-Vlanif30]vrrp vrid 10 virtual-ip 192.168.30.250
[Gw20-Vlanif30]vrrp vrid 10 priority 150(配置优先级)
Vlan40: [Gw20]in vlan 40
[Gw20-Vlanif40]vrrp vrid 20 virtual-ip 192.168.40.250
[Gw20-Vlanif40]vrrp vrid 20 priority 150
Pc1;192.168.10.250 255.255.255.0
Pc2: 192.168.20.250 255.255.255.0
Pc3: 192.168.30.250 255.255.255.0
Pc4: 192.168.40..250 255.255.255.0
在GW19和GW20中配置SVI ip地址,分别是;
Vlan x 192.168.x.254/24和192.168.x.25324
线路1或2故障时,vlan10 vlan20 会使用备份电路,整个网络还是通的,平时则会使用GW19,解决单点链路故障,实现了负载均衡
如果线路3或4故障时,可以在端口下设置命令:
[Gw19-Vlanif20]Vrrp vrid x track interface gi 0/0/2(监控上一端口状态)
[Gw19-Vlanif20]vrrp vrid 10 track int gi 0/0/2 reduced
50(当0/0/2端口down时,其相应的优先级会减少这就是VRRP的负载均衡以及链路跟踪
希望对大家有点帮助,如果有什么不对的地方请大家一定要提出来,一起探讨!!!
