CCNP(BCMSN)实验：HSRP实验（热备份路由协议）

CCNP(BCMSN)实验：HSRP实验（热备份路由协议）

本实验目的及要求

我们为了使pc4、5有一个良好的上网环境给pc4、5做了热备份路由 正常从R1经过，R1挂掉之后，走R3 当R1修好时又走R1 R1的外网链路断的之后，又走R3，并且在R1修好时又走R1 在R1和R2上关闭icmp重定向和proxy-arp 多组使R1的组1为活动，R2为组1的备份 多组使R2的组2为活动，R1为组2的备份

实验过程：第一步：给各个路由器的接口配置ip地址，然后启用eigrp协议，关闭R4、5的ip路由功能R2(config)#router eigrp 1R2(config-router)#no auR2(config-router)#net 12.0.0.2 0.0.0.0R2(config-router)#net 2.2.2.2 0.0.0.0R2(config-router)#net 23.0.0.2 0.0.0.0其它略

第二步：在R1、R3上启用hsrp

以下为组1的配置

R1上的配置：interface FastEthernet0/0ip address 192.168.1.1 255.255.255.0no ip redirectsno ip proxy-arp//以上两步为关闭反向ARP和icmp重定向standby 1 ip 192.168.1.144 //设置虚拟的ip地址standby 1 preempt //开启R1的抢占功能standby 1 priority 105 //设置组1的优先级standby 1 track Serial2/1 //开启外网接口的追踪，后面有一个默认值为10

R3上的配置：interface FastEthernet0/0ip address 192.168.1.3 255.255.255.0standby 1 ip 192.168.1.144standby 1 ip preempt //在这里开启抢占是为了在R1的外网挂了之后，R3去抢占

以下为组2上配置

R3上的配置interface FastEthernet0/0ip address 192.168.1.3 255.255.255.0standby 2 ip 192.168.1.155standby 2 priority 105standby 2 track Serial2/1standby 2 preempt

R1上的配置

interface FastEthernet0/0ip address 192.168.1.1 255.255.255.0standby 2 ip 192.168.1.155standby 2 preempt

第三步：测试pc4在测试过程中关闭f0/0接口PC4#ping 2.2.2.2 repeat 9999999

Type escape sequence to abort.Sending 9999999, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.....!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.Success rate is 97 percent (239/245), round-trip min/avg/max = 24/78/144 msPC4#traceroute 2.2.2.2

1.我们先关闭内网的接口R1(config)#int f0/0R1(config-if)#shApr 17 11:39:03.523: %HSRP-5-STATECHANGE: FastEthernet0/0 Grp 1 state Active -> InitApr 17 11:39:03.587: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 192.168.1.3 (FastEthernet0/0) is down: interface downApr 17 11:39:05.519: %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to administratively downApr 17 11:39:06.519: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to downR1(config-if)#no shApr 17 11:39:23.959: %HSRP-5-STATECHANGE: FastEthernet0/0 Grp 1 state Listen -> Active//当打开f0/0时，实现了无缝切换Apr 17 11:39:24.563: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to upApr 17 11:39:25.399: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 192.168.1.3 (FastEthernet0/0) is up: new adjacencyApr 17 11:39:25.563: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

2.我们再关闭外网的接口R1(config-if)#int s2/1R1(config-if)#sh R1上的情况Apr 17 13:00:56.791: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 12.0.0.2 (Serial2/1) is down: interface downApr 17 13:00:58.735: %LINK-5-CHANGED: Interface Serial2/1, changed state to administratively downApr 17 13:00:59.735: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/1, changed state to downApr 17 13:00:59.739: %HSRP-5-STATECHANGE: FastEthernet0/0 Grp 1 state Active -> SpeakR1(config-if)#no shApr 17 13:13:03.967: %LINK-3-UPDOWN: Interface Serial2/1, changed state to upApr 17 13:13:04.971: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/1, changed state to upR1(config-if)#*Apr 17 13:13:06.823: %HSRP-5-STATECHANGE: FastEthernet0/0 Grp 1 state Standby -> Active
