1. 在R2和R3之间配置HSRP，虚拟ip地址为1.1.234.254。在R2和R3上show 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Active，Active/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. 在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R4上traceroute 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，R3的priority减15。

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. 在R2和R3上删除HSRP的配置。在R2和R3上分别配置Group1和Group2的HSRP，虚拟IP地址分别为1.1.234.253，1.1.234.254。确保R2成为Group1的Active状态，R3成为Group2的Active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R4和R5上traceroute 1.1.1.1，观察现象。

R2 R3：

interface FastEthernet0/0

no standby 1

R2：

interface FastEthernet0/0

standby 1 ip 1.1.234.253

standby 1 priority 101

standby 1 preempt

standby 2 ip 1.1.234.254

R3：

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)

7. 删除第7题的配置。在R2和R3上配置GLBP，虚拟ip地址为1.1.234.254，确保R2成为AVG Active，将R4和R5的默认网关均配置为1.1.234.254，在R4和R5上traceroute 1.1.1.1，观察现象。

R2 R3：

interface FastEthernet0/0
