1.      R2R3之间配置HSRP,虚拟ip地址为1.1.234.254。在R2R3show standby观察HSRP的状态信息。

R2 R3

interface FastEthernet0/0

 standby 1 ip 1.1.234.254     //先在R2上配置,再在R3上配置。

R2#show standby

FastEthernet0/0 - Group 1

  State is Active    //R2的状态为ActiveActive/Standby默认是关抢占的,先在R2上做的配置。

    2 state changes, last state change 00:00:40

  Virtual IP address is 1.1.234.254

  Active virtual MAC address is 0000.0c07.ac01

    Local virtual MAC address is 0000.0c07.ac01 (default)

  Hello time 3 sec, hold time 10 sec

    Next hello sent in 1.200 secs

  Preemption disabled

  Active router is local

  Standby router is 1.1.234.3, priority 100 (expires in 8.812 sec)

  Priority 100 (default 100)

  IP redundancy name is "hsrp-Fa0/0-1" (default)

 

R3#show standby

FastEthernet0/0 - Group 1

  State is Standby     //R3的状态为Standby

    1 state change, last state change 00:01:38

  Virtual IP address is 1.1.234.254

  Active virtual MAC address is 0000.0c07.ac01

    Local virtual MAC address is 0000.0c07.ac01 (default)

  Hello time 3 sec, hold time 10 sec

    Next hello sent in 0.556 secs

  Preemption disabled

  Active router is 1.1.234.2, priority 100 (expires in 6.952 sec)

  Standby router is local

  Priority 100 (default 100)

  IP redundancy name is "hsrp-Fa0/0-1" (default)

3.      R3上开启针对上行接口的跟踪,若是上行接口down掉,让R2成为Acitve状态。此时在R4traceroute 1.1.1.1,观察现象。

R3

interface FastEthernet0/0

 standby 1 track Serial1/1 15    //R3的上行接口S1/1down掉,R3priority15

 

interface Serial1/1

 shutdown

 

R3

show standby

FastEthernet0/0 - Group 1

  State is Standby

    4 state changes, last state change 00:00:07

  Virtual IP address is 1.1.234.254

  Active virtual MAC address is 0000.0c07.ac01

    Local virtual MAC address is 0000.0c07.ac01 (default)

  Hello time 3 sec, hold time 10 sec

    Next hello sent in 1.592 secs

  Preemption enabled

  Active router is 1.1.234.2, priority 100 (expires in 7.620 sec)

  Standby router is local

  Priority 88 (configured 103)

    Track interface Serial1/1 state Down decrement 15

  IP redundancy name is "hsrp-Fa0/0-1" (default)

R4

R4#traceroute 1.1.1.1

Tracing the route to 1.1.1.1

  1 1.1.234.2 56 msec 36 msec 20 msec

  2 1.1.13.1 16 msec *  32 msec

5.      R2R3上删除HSRP的配置。在R2R3上分别配置Group1Group2HSRP,虚拟IP地址分别为1.1.234.2531.1.234.254。确保R2成为Group1Active状态,R3成为Group2Active状态。将R4的默认网关配置为1.1.234.253,关闭R5的路由功能,让其模拟主机,配置默认网关为1.1.234.254。在R4R5traceroute 1.1.1.1,观察现象。

R2 R3

 no standby 1

R2

interface FastEthernet0/0

standby 1 ip 1.1.234.253

 standby 2 ip 1.1.234.254

 standby 2 priority 101

 standby 2 preempt

R2

show standby

FastEthernet0/0 - Group 1

  State is Active

    1 state change, last state change 00:01:53

  Virtual IP address is 1.1.234.253

  Active virtual MAC address is 0000.0c07.ac01

    Local virtual MAC address is 0000.0c07.ac01 (default)

  Hello time 3 sec, hold time 10 sec

    Next hello sent in 0.456 secs

  Preemption enabled

  Active router is local

  Standby router is 1.1.234.3, priority 100 (expires in 9.296 sec)

  Priority 101 (configured 101)

  IP redundancy name is "hsrp-Fa0/0-1" (default)

 

FastEthernet0/0 - Group 2

  State is Standby

    4 state changes, last state change 00:01:15

    Local virtual MAC address is 0000.0c07.ac02 (default)

  Hello time 3 sec, hold time 10 sec

    Next hello sent in 2.036 secs

7.      删除第7题的配置。在R2R3上配置GLBP,虚拟ip地址为1.1.234.254,确保R2成为AVG Active,将R4R5的默认网关均配置为1.1.234.254,在R4R5traceroute 1.1.1.1,观察现象。
