VRRP配置
1、SW1配置
en vlan data vtp domain 2014 vtp server vlan 2 vlan 3 exit conf t int f1/1 switch mode trunk int f1/15 switch mode trunk int f1/0 no switch ip add 192.168.1.1 255.255.255.0 no sh int vlan 2 ip add 192.168.2.1 255.255.255.0 no sh int vlan 3 ip add 192.168.3.1 255.255.255.0 no sh exit track 2 int f1/0 line-protocol //配置需要跟踪的端口 exit int vlan 2 vrrp 2 ip 192.168.2.254 vrrp 2 pri 150 vrrp 2 pree vrrp 2 track 2 decrement 100 int vlan 3 vrrp 3 ip 192.168.3.254 vrrp 3 pree exit spanning-tree vlan 2 root primary span vlan 3 root secondary ip route 0.0.0.0 0.0.0.0 192.168.1.2 do show vrrp br //查看vrrp配置
2、SW2配置
en vlan data vtp domain 2014 vtp server exit conf t int f1/2 switch mode trunk int f1/15 switch mode trunk int f1/0 no switch ip add 192.168.4.1 255.255.255.0 no sh int vlan 2 ip add 192.168.2.2 255.255.255.0 no sh int vlan 3 ip add 192.168.3.2 255.255.255.0 no sh int vlan 3 vrrp 3 ip 192.168.3.254 vrrp 3 pri 150 vrrp 3 pree vrrp 3 track 3 decrement 100 int vlan 2 vrrp 2 ip 192.168.2.254 vrrp 2 pree exit track 3 int f1/0 line-protocol spanning-tree vlan 3 root primary span vlan 2 root secondary ip route 0.0.0.0 0.0.0.0 192.168.4.2
3、SW3配置
en vlan data vtp domain 2014 vtp client exit conf t int rang f1/1 - 2 sw mode trunk int f1/3 sw acc vlan 2 int f1/4 sw ac vl 3
4、R1配置
en conf t int f0/1 ip add 192.168.1.2 255.255.255.0 no sh int f0/0 ip add 192.168.4.2 255.255.255.0 no sh int loop0 ip add 192.168.10.1 255.255.255.0 no sh exit ip route 192.168.2.0 255.255.255.0 192.168.1.1 ip route 192.168.2.0 255.255.255.0 192.168.4.1 50 ip route 192.168.3.0 255.255.255.0 192.168.4.1 ip route 192.168.3.0 255.255.255.0 192.168.1.1 50
5、PC配置
C1:192.168.2.3/24 GW:192.168.2.254 C2:192.168.3.3/24 GW:192.168.3.254
6、测试
把SW2的f1/0口shutdown 后测试并跟踪
