MGRE实验
MGRE实验
一、实验要求
二、实验拓扑
三、实验步骤
1、地址分配配置（R2为ISP，其上只能配置IP地址）
R1的配置：
[r1-GigabitEthernet0/0/1]ip add 192.168.1.1 24
[r1-GigabitEthernet0/0/1]in s4/0/0
[r1-Serial4/0/0]ip add 12.1.1.1 24
R2的配置：
[ISP-Serial4/0/1]ip add 12.1.1.2 24
ISP-Serial4/0/1]in s3/0/0
[ISP-Serial3/0/0]ip add 23.1.1.1 24
[ISP-Serial3/0/0]in s4/0/0
[ISP-Serial4/0/0]ip add 24.1.1.1 24
[ISP-Serial4/0/0]in lo0
[ISP-LoopBack0]ip add 2.2.2.2 24
R3的配置：
[r3]in s4/0/1
[r3-Serial4/0/1]ip add 23.1.1.2 24
[r3-GigabitEthernet0/0/0]ip add 192.168.2.1 24
R4的配置：
[r4-Serial4/0/0]in s4/0/1
[r4-Serial4/0/1]ip add 24.1.1.2 24
[r4-Serial4/0/1]
[r4-GigabitEthernet0/0/0]ip add 192.168.3.1 24
2、R1-R2之间为HDLC封装
R1的配置：
[r1]in s4/0/0
[r1-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y
R2的配置：
[ISP]in s4/0/1
[ISP-Serial4/0/1]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y
3、R2-R3之间为PPP封装，pap认证，R2为主认证方
由于配置默认为PPP封装，所以R2-R3与R3-R4之间封装不用修改
R2的配置：
[ISP]aaa
ISP-aaa]local-user huawei password cipher huawei123
[ISP-aaa]local-user huawei service-type ppp
[ISP]in s3/0/0
[ISP-Serial3/0/0]ppp authentication-mode pap
R3的配置：
[r3]in s4/0/1
[r3-Serial4/0/1]ppp pap local-user huawei password cipher huawei123
4、R2-R4之间为PPP封装，chap认证，R2为主认证方
R2的配置：
[ISP]in s4/0/0
[ISP-Serial4/0/0]ppp authentication-mode chap
R4的配置：
[r4]in s4/0/1
[r4-Serial4/0/1]ppp chap user huawei
[r4-Serial4/0/1]ppp chap password cipher huawei123
5、R1、R2、R3构建MGRE环境，仅R1IP地址固定
R1的配置：
[r1]in t0/0/0
[r1-Tunnel0/0/0]ip add 10.1.1.1 24
[r1-Tunnel0/0/0]tunnel-protocol gre p2mp
[r1-Tunnel0/0/0]source 12.1.1.1
[r1-Tunnel0/0/0]nhrp entry multicast dynamic
[r1-Tunnel0/0/0]nhrp network-id 100
r1]ip route-static 0.0.0.0 0 12.1.1.2
R3的配置：
[r3]in t0/0/0
[r3-Tunnel0/0/0]ip add 10.1.1.2 24
[r3-Tunnel0/0/0]tunnel-protocol gre p2mp
[r3-Tunnel0/0/0]source s4/0/1
[r3-Tunnel0/0/0]nhrp entry 10.1.1.1 12.1.1.1 register
[r3-Tunnel0/0/0]nhrp network-id 100
[r3]ip route-static 0.0.0.0 0 23.1.1.1
R4的配置：
[r4-Tunnel0/0/0]ip add 10.1.1.3 24
[r4-Tunnel0/0/0]tunnel-protocol gre p2mp
[r4-Tunnel0/0/0]source s4/0/1
[r4-Tunnel0/0/0]nhrp entry 10.1.1.1 12.1.1.1 register
[r4-Tunnel0/0/0]nhrp network-id 100
[r4]ip route-static 0.0.0.0 0 24.1.1.1
6、内网使用RIP获取路由，所有PC可以互相访问，并且可访问R2的环回
R1的配置：
[r1]rip 1
[r1-rip-1]version 2
[r1-rip-1]network 192.168.1.0
[r1-rip-1]network 10.0.0.0
[r1]in t0/0/0
[r1-Tunnel0/0/0]undo rip split-horizon
[r1]acl 2000
[r1-acl-basic-2000]rule permit source any
[r1]in s4/0/0
[r1-Serial4/0/0]nat outbound 2000
R3的配置：
[r3]rip 1
[r3-rip-1]version 2
[r3-rip-1]network 192.168.2.0
[r3-rip-1]network 10.0.0.0
[r3]acl 2000
[r3-acl-basic-2000]rule permit source any
[r3]in s4/0/1
[r3-Serial4/0/1]nat outbound 2000
R4的配置：
[r4]rip 1
[r4-rip-1]version 2
[r4-rip-1]network 192.168.3.0
[r4-rip-1]network 10.0.0.0
[r4]acl 2000
[r4-acl-basic-2000]rule permit source any
[r4-acl-basic-2000]in s4/0/1
[r4-Serial4/0/1]nat outbound 2000
