第一步：配置R2、R4和R5Pc4上的配置：interface FastEthernet0ip address 192.168.1.4 255.255.255.0ip default-gateway
.
第一步：配置R2、R4和R5
Pc4上的配置：
interface FastEthernet0
ip address 192.168.1.4 255.255.255.0
ip default-gateway 192.168.1.254
pc5上的配置
interface FastEthernet0
ip address 192.168.1.5 255.255.255.0
ip default-gateway 192.168.1.253
R2上的配置
interface FastEthernet0/0
ip address 12.0.0.2 255.255.255.0
interface FastEthernet0/1
ip address 23.0.0.2 255.255.255.0
router eigrp 1
network 2.0.0.0
network 12.0.0.0
network 23.0.0.0
no auto-summary
第二步：配置sw1和sw3，我们要求sw1为组1的主路由器，为组2的备路由器
SW2为组2的主路由器，为组1的备路由器
SW3上的配置：
track 10 interface FastEthernet0/0 line-protocol
//配置要追踪的接口，和hsrp不太一样
interface Vlan1
ip address 192.168.1.3 255.255.255.0
no ip redirects
no ip proxy-arp
vrrp 1 ip 192.168.1.254
vrrp 1 timers advertise 3
vrrp 2 ip 192.168.1.253
vrrp 2 timers advertise 3
vrrp 2 priority 105
vrrp 2 track 10
!
router eigrp 1
network 23.0.0.0
network 192.168.1.0
no auto-summary
SW1上的配置：
track 10 interface FastEthernet0/0 line-protocol
interface Vlan1
ip address 192.168.1.1 255.255.255.0
no ip redirects
no ip proxy-arp
vrrp 1 ip 192.168.1.254
vrrp 1 timers advertise 3
vrrp 1 priority 105
vrrp 1 track 10
vrrp 2 ip 192.168.1.253
vrrp 2 timers advertise 3
router eigrp 1
network 12.0.0.0
network 192.168.1.0
no auto-summary
第三步：测试
- 我们先在sw1上进行测试
SW1上的信息：
sw1(config)#int f0/1
sw1(config-if)#sh
Mar 1 01:55:07.315: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Master -> Init
Mar 1 01:55:07.319: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Backup -> Init
//down掉f0/1的接口时，他们进入了初始化姿态
sw1(config-if)#no sh
Mar 1 01:55:25.435: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Init -> Backup
Mar 1 01:55:25.435: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Init -> Backup
//打开接口时，他们都会备份路由器
Mar 1 01:55:35.027: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Backup -> Master
Mar 1 01:55:35.047: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Backup -> Master
//在过了一段时间后，他们都说自己为主路由器，但是经过一段时间的协商后，他确定了自己的身份为组2的备份路由器
*Mar 1 01:55:55.227: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Master -> Backup
sw1(config-if)#int f0/0
sw1(config-if)#sh
Mar 1 01:56:18.423: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Master -> Backup
//关闭f0/0后，由于追踪的原因此路由器成为组1的备份路由器
sw1(config-if)#no sh
Mar 1 01:56:40.839: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Backup -> Master
//我们又打开后，他恢复了他的master身份
在此同时，sw3上出现了下列信息
Mar 1 01:55:15.839: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Backup -> Master
Mar 1 01:55:55.603: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Master -> Backup
Mar 1 01:56:18.319: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Backup -> Master
Mar 1 01:56:40.895: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Master -> Backup
//从上面我们看到在sw1上的两个接口down和up后，他先后经过2次路由master>>>>backup的转变，这表示切换成功
我们又看看pc4上的反应
pc4#ping 2.2.2.2 re 2222222
Type escape sequence to abort.
Sending 2222222, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:

Success rate is 96 percent (842/872), round-trip min/avg/max = 28/64/1080 ms
//从pc4上我们看到了在两次切换过程中留下的足迹。成功了，但是有点慢
- 我们在来测试SW3
sw3(config)#int f0/1
sw3(config-if)#sh
Mar 1 02:10:22.299: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Backup -> Init
Mar 1 02:10:22.303: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Master -> Init
//down接口，它们进入初始化状态
但是在SW1上看上到它成为了主路由器
*Mar 1 02:10:30.391: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Backup -> Master
sw3(config-if)#no sh
Mar 1 02:10:57.175: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Backup -> Master
Mar 1 02:10:57.191: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Backup -> Master
sw3(config-if)#
//打开接口时，它们都称为自己为master，但是经过一定时间的协商后，SW1出现了下而一行信息
*Mar 1 02:11:19.559: %VRRP-6-STATECHANGE: Vl1 Grp 1 state Master -> Backup
//它称自己为组1的备份路由器
sw3(config-if)#int f0/0
sw3(config-if)#sh
*Mar 1 02:12:05.887: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Master -> Backup
//down这个接口后，由于追踪，它称自己为组2的备份路由器
sw3(config-if)#no sh
*Mar 1 02:12:23.075: %VRRP-6-STATECHANGE: Vl1 Grp 2 state Backup -> Master
//打开后，双成为组2的master
我们再来看看pc5的通信情况
pc5#ping 2.2.2.2 re 2222222
Type escape sequence to abort.
Sending 2222222, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
