mgre实验

实验要求：

1.R5为ISP，只能进行IP地址配置，其所有地址均为公有IP地址
2.R1和R5间使用PPP的PAP认证，R5为主认证方;R2与R5之间使用PPP的chap认证，R5为主认证方;R3与R5之间使用HDLC封装。
3.R1/R2/R3构建一个MGRE环境，R1为中心站点;R1、R4间为点到点的GRE。
4.整个私有网络基于RIP全网可达。
5.所有Pc设置私有IP为源IP，可以访问R5环回。

第一步：按照实验网络划分配置接口IP

第二步：在R1,R2,R5之间配置PAP，chap认证

R5主认证方

[ISP]aaa
[ISP-aaa]local-user huazhu password cipher 123456
Info: Add a new user.
[ISP-aaa]local-user huazhu service-type ppp
[ISP]int s 3/0/0	
[ISP-Serial3/0/0]ppp authentication-mode pap	
[ISP]int s 3/0/1
[ISP-Serial3/0/1]ppp authentication-mode chap

R1 PAP认证

[r1-GigabitEthernet0/0/0]int s 4/0/0
[r1-Serial4/0/0]ppp pap local-user huazhu password cipher 123456

R2 chap认证

[r2]int Serial 4/0/0	
[r2-Serial4/0/0]ppp chap user huazhu	
[r2-Serial4/0/0]ppp chap password cipher 123456

第三步：R3与R5之间使用HDLC封装

[r3-Serial4/0/0]link-protocol hdlc
[ISP-Serial4/0/0]link-protocol hdlc

第四步：R1/R2/R3构建一个MGRE环境，R1为中心站点

在构建前要保证公网联通

[r1]ip route-static 0.0.0.0 0 15.0.0.2
[r2]ip  route-static 0.0.0.0 0 25.0.0.2
[r3]ip route-static 0.0.0.0 0 35.0.0.2
[r4]ip route-static 0.0.0.0 0 45.0.0.2

R1配置

[r1]int Tunnel 0/0/0
[r1-Tunnel0/0/0]ip address 192.168.5.1 24
[r1-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r1-Tunnel0/0/0]source 15.0.0.1
[r1-Tunnel0/0/0]nhrp network-id 500

R2配置

[r2]int Tunnel 0/0/0
[r2-Tunnel0/0/0]ip address 192.168.5.2 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 500
[r2-Tunnel0/0/0]nhrp entry 192.168.5.1 15.0.0.1 re	

R3配置

[r3]int Tunnel 0/0/0
[r3-Tunnel0/0/0]ip address 192.168.5.3 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 500	
[r3-Tunnel0/0/0]nhrp entry 192.168.5.1 15.0.0.1 register 

第五步：R1、R4间为点到点的GRE

R1配置

[r1-Tunnel0/0/0]int tu 0/0/1
[r1-Tunnel0/0/1]ip address 192.168.6.1 24
[r1-Tunnel0/0/1]tunnel-protocol gre 
[r1-Tunnel0/0/1]source 15.0.0.1
[r1-Tunnel0/0/1]destination 45.0.0.1

R4配置

[r4]interface Tunnel 0/0/0
[r4-Tunnel0/0/0]ip address 192.168.6.2 24
[r4-Tunnel0/0/0]tunnel-protocol gre 
[r4-Tunnel0/0/0]source 45.0.0.1
[r4-Tunnel0/0/0]destination 15.0.0.1

第六步：整个私有网络基于RIP全网可达

[r1]rip 
[r1-rip-1]version 2
[r1-rip-1]network 192.168.1.0
[r1-rip-1]network 192.168.5.0
[r1-rip-1]network 192.168.6.0
[r1-rip-1]int s 4/0/0
[r1-Serial4/0/0]q
[r1]int t 0/0/0
[r1-Tunnel0/0/0]nhrp entry multicast dynamic 
[r1-Tunnel0/0/0]undo rip split-horizon

[r2]rip 
[r2-rip-1]version 2
[r2-rip-1]network 192.168.2.0

第七步：所有Pc设置私有IP为源IP，可以访问R5环回

R5配置
