HSRP與VRRP雙主雙備、均衡負載
HSRP配置命令
m1(config-if)#standby 1 ip 192.168.10.200 配置虛擬網關
m1(config-if)#standby 1 priority 120 配置優先級，默認爲100
m1(config-if)#standby 1 preempt 配置搶佔權
m1(config-if)#standby 1 timers 3 10 配置hello時間
m1(config-if)#standby 1 track fastEthernet 0/1 配置端口跟蹤
m1#show standby 查看HSRP信息
m1#show standby brief 查看HSRP摘要信息
VRRP配置命令
m1(config-if)#vrrp 1 ip 192.168.10.200 配置虛擬網關
m1(config-if)#vrrp 1 priority 120 配置優先級，默認爲100
m1(config-if)#vrrp 1 preempt 配置搶佔權
m1(config)#track 3 interface fastEthernet 1/0 line-protocol 配置端口跟蹤索引
m1(config-if)#vrrp 1 track 3 配置端口跟蹤
m1#show vrrp 查看vrrp信息
m1#show vrrp brief 查看vrrp摘要信息
例：
HRRP及VRRP綜合實驗
實驗要求：
1.c1、c2、c3、c4、分別屬於vlan10、vlan20、vlan30、vlan40
2.vlan10和vlan30流量默認從sw1通過，vlan20和vlan40流量默認從sw2經過，當鏈路出故障，實現流量倒換
3.vlan10、valn20、vlan30配置HSRP思科私有協議，vlan40配置VRRP標準協議
