HCIP作业3——MGRE综合实验

一、实验及拓扑

二、实验步骤

1、配置IP

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.254 24
[R1-GigabitEthernet0/0/0]int s4/0/0
[R1-Serial4/0/0]ip add 15.1.1.1 24
[R1-Serial4/0/0]quit

[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip add 192.168.2.254 24
[R2-GigabitEthernet0/0/0]int s4/0/0
[R2-Serial4/0/0]ip add 25.1.1.2 24
[R2-Serial4/0/0]quit

[R3]int g0/0/0
[R3-GigabitEthernet0/0/0]ip add 192.168.3.254 24
[R3-GigabitEthernet0/0/0]int s4/0/0
[R3-Serial4/0/0]ip add 35.1.1.3 24
[R3-Serial4/0/0]quit

[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]ip add 45.1.1.4 24
[R4-GigabitEthernet0/0/0]int g0/0/1
[R4-GigabitEthernet0/0/1]ip add 192.168.4.254 24
[R4-GigabitEthernet0/0/1]quit

[R5]int s4/0/1
[R5-Serial4/0/1]ip add 15.1.1.5 24
[R5-Serial4/0/1]int s3/0/1
[R5-Serial3/0/1]ip add 25.1.1.5 24
[R5-Serial3/0/1]int s4/0/0
[R5-Serial4/0/0]ip add 35.1.1.5 24
[R5-Serial4/0/0]int g0/0/0
[R5-GigabitEthernet0/0/0]ip add 45.1.1.5 24[R5]int l0
[R5-LoopBack0]ip add 5.5.5.5 24
[R5-LoopBack0]quit

2、认证

①PAP认证

R5（主认证方）

[R5]aaa
[R5-aaa]local-user wangdaye password cipher wdy12345
[R5-aaa]local-user wangdaye service-type ppp
[R5-aaa]quit[R5]int s4/0/1
[R5-Serial4/0/1]ppp authentication-mode pap
[R5-Serial4/0/1]quit

R1（被认证方）

[R1]int s4/0/0
[R1-Serial4/0/0]ppp pap local-user wangdaye password cipher way12345

用shutdown和undo shutdown做测试后，ping一下

②CHAP认证

R5（主认证方）【用刚刚创建的用户】

[R5]int s3/0/1
[R5-Serial3/0/1]ppp authentication-mode chap
[R5-Serial3/0/1]quit

R2（被认证方）

[R2]int s4/0/0
[R2-Serial4/0/0]ppp chap user wangdaye
[R2-Serial4/0/0]ppp chap  password cipher wdy12345
[R2-Serial4/0/0]quit

同上，用shutdown和undo shutdown做测试后，ping一下

③HDLC封装

查看协议
[R3]int s4/0/0
[R3-Serial4/0/0]dis th
[V200R003C00]
#
interface Serial4/0/0link-protocol pppip address 35.1.1.3 255.255.255.0 
#
return
修改协议
[R3-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y

检查

[R5]int s4/0/0
[R5-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y

检查

3、构建环境

①公网通（静态缺省）

R1
[R1]ip route-static 0.0.0.0 0 15.1.1.5R2
[R2]ip route-static 0.0.0.0 0 25.1.1.5R3
[R3]ip route-static 0.0.0.0 0 35.1.1.5R4
[R4]ip route-static 0.0.0.0 0 45.1.1.5

②检测

测R1的公网

测R2的公网

测R3的公网

③构建隧道

MGRE

[R1]int Tunnel 0/0/0
[R1-Tunnel0/0/0]ip add 10.1.1.1 24
[R1-Tunnel0/0/0]tunnel-protocol gre p2mp
[R1-Tunnel0/0/0]source 15.1.1.1
Jul 26 2024 03:01:38-08:00 R1 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP 
on the interface Tunnel0/0/0 has entered the UP state. 
[R1-Tunnel0/0/0]NHRP network-id 100

[R2]int Tunnel 0/0/0
[R2-Tunnel0/0/0]ip add 10.1.1.2 24
[R2-Tunnel0/0/0]tunnel-protocol gre p2mp
[R2-Tunnel0/0/0]source serial 4/0/0
[R2-Tunnel0/0/0]nhrp network-id 100
[R2-Tunnel0/0/0]nhrp entry 10.1.1.1 15.1.1.1 register

[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]ip add 10.1.1.3 24
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp
[R3-Tunnel0/0/0]source serial 4/0/0
[R3-Tunnel0/0/0]nhrp network-id 100
[R3-Tunnel0/0/0]nhrp entry 10.1.1.1 15.1.1.1 register

GRE

[R1]int Tunnel 0/0/1 
[R1-Tunnel0/0/1]ip add 10.1.2.1 24
[R1-Tunnel0/0/1]tunnel-protocol gre
[R1-Tunnel0/0/1]source 15.1.1.1
[R1-Tunnel0/0/1]destination 45.1.1.4

[R4]int Tunnel 0/0/1
[R4-Tunnel0/0/1]ip add 10.1.2.4 24
[R4-Tunnel0/0/1]tunnel-protocol gre
[R4-Tunnel0/0/1]source 45.1.1.4
[R4-Tunnel0/0/1]destination 15.1.1.1

4、配置RIP协议

[R1]rip 1
[R1-rip-1]v 2
[R1-rip-1]undo su
[R1-rip-1]net 192.168.1.0
[R1-rip-1]net 10.0.0.0

[R2]rip 1
[R2-rip-1]v 2
[R2-rip-1]undo su
[R2-rip-1]ne 192.168.2.0
[R2-rip-1]ne 10.0.0.0

[R3]rip 1
[R3-rip-1]v 2
[R3-rip-1]undo summary
[R3-rip-1]ne 192.168.3.0
[R3-rip-1]ne 10.0.0.0

[R4]rip 1
[R4-rip-1]v 2
[R4-rip-1]undo su
[R4-rip-1]ne 192.168.4.0
[R4-rip-1]ne 10.0.0.0
[R4-rip-1]quit

因为MGRE学不全，所以进行如下操作：（伪广播）

[R1]int Tunnel 0/0/0
[R1-Tunnel0/0/0]nhrp entry multicast dynamic
[R1-Tunnel0/0/0]undo rip split-horizon

[R2]int t0/0/0
[R2-Tunnel0/0/0]undo rip split-horizon

[R3]int t0/0/0
[R3-Tunnel0/0/0]undo rip split-horizon

5、做net

[R1]acl 2000
[R1-acl-basic-2000]rule per
[R1-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[R1-acl-basic-2000]quit
[R1]int s4/0/0
[R1-Serial4/0/0]nat outbound 2000
[R1-Serial4/0/0]quit

[R2]acl 2000
[R2-acl-basic-2000]rule per
[R2-acl-basic-2000]rule permit source 192.168.3.0 0.0.0.255
[R2-acl-basic-2000]quit
[R2]int s4/0/0
[R2-Serial4/0/0]nat outbound 2000

[R3-acl-basic-2000]rule per
[R3-acl-basic-2000]rule permit source 192.168.3.0 0.0.0.255
[R3-acl-basic-2000]quit
[R3]int s4/0/0
[R3-Serial4/0/0]nat outbound 2000
[R3-Serial4/0/0]quit

[R4]acl 2000
[R4-acl-basic-2000]rule per
[R4-acl-basic-2000]rule permit source 192.168.4.0 0.0.0.255
[R4-acl-basic-2000]quit
[R4]int g0/0/0
[R4-Serial4/0/0]nat outbound 2000
[R4-Serial4/0/0]quit
