實驗過程
1. pc的配置
|
Router>en Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line con 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#host pc pc(config)#no ip routing pc(config)#int f0/0 pc(config-if)#no shut pc(config-if)#ip add 192.168.1.1 255.255.255.0 pc(config-if)#exit pc(config)#ip default-gateway 192.168.1.254 pc(config)#end |
2. R1的配置
|
Router>en Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line con 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#host R1 R1(config)#int f0/0 R1(config-if)#no shut R1(config-if)#ip add 192.168.1.10 255.255.255.0 R1(config-if)#standby 10 ip 192.168.1.254 //配置hsrp組10的IP |
3. R2的配置
|
Router>en Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no ip domain-lookup Router(config)#line con 0 Router(config-line)#no exec-timeout Router(config-line)#loggin syn Router(config-line)#exit Router(config)#host R2 R2(config)#int f0/0 R2(config-if)#no shut R2(config-if)#ip add 192.168.1.20 255.255.255.0 R2(config-if)#standby 10 ip 192.168.1.254 R2(config-if)#end |
4. 查看HSRP信息
|
R1#show standby brief P indicates configured to preempt. | Interface Grp Prio P State Active Standby Virtual IP Fa0/0 10 100 P Active local 192.168.1.20 192.168.1.254 R2#show standby brief P indicates configured to preempt. | Interface Grp Prio P State Active Standby Virtual IP Fa0/0 10 100 P Standby 192.168.1.10 local 192.168.1.254 |
說明：現在R1是Active Router，R2是Standby Router。
5. 測試連通性
|
pc#ping 192.168.1.254 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.254, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/224/1064 ms pc#traceroute 192.168.1.254 Type escape sequence to abort. Tracing the route to 192.168.1.254 1 192.168.1.10 28 msec * 20 msec //pc走的是R1 |
6. 關閉R1的f0/0口，模擬故障
|
R1(config)#int f0/0 R1(config-if)#shut R2#show standby bri P indicates configured to preempt. | Interface Grp Prio P State Active Standby Virtual IP Fa0/0 10 100 P Active local unknown 192.168.1.254 |
說明：現在R2是Active Router。
7. 測試連通性
