[HCIP] MGRE基础实验-优快云博客

本文详细描述了一个实验过程，包括分配IP地址、路由器间的HDLC和PPP封装、MGRE隧道配置、RIP路由协议应用，以及内网间通过PPP和RIP实现的路由可达性和互访测试。

一.实验需求及拓扑

二.实验规划

1.先分配IP地址
2.对各路由器进行封装
3.所有的边界路由器发一条缺省指向isp,实现公网的全网可达。
4.构建MGRE环境：
5.内网使用RIP获取路由，通过关闭水平分割来实现路由的全网正常收敛。

三.实验步骤

1.在r1r2间进行HDLC封装

R1：
[R1]int s4/0/0
[R1-Serial4/0/0]ip add 12.1.1.1 24
[R1-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
y
R2：
[ISP]int s4/0/0
[ISP-Serial4/0/0]ip add 12.1.1.2 24
[ISP-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]

2.r2r3间为ppp封装，pap认证，r2是主认证方

r2：[ISP]aaa
[ISP-aaa]local-user ddd password cipher 123456
[ISP-aaa]local-user ddd service-type ppp
[ISP]int s4/0/1
[ISP-Serial4/0/1]ppp authentication-mode pap

R3：[R3]int s4/0/0
[R3-Serial4/0/0]ppp pap local-user ddd sword cipher 123456

3.r2r4之间为ppp封装，chap认证，r2为主认证方

r2：[ISP]aaa
[ISP-aaa]local-user ccc password cipher 123456
[ISP-aaa]local-user ccc service-type ppp
[ISP]int s3/0/0
[ISP-Serial3/0/0]ppp authentication-mode chap
r4： [R4]int s4/0/0
[R4-Serial4/0/0]ppp chap user ccc
[R4-Serial4/0/0]ppp chap password cipher 123456

4. r1(r1IP地址固定)、r2、r3构建MGRE环境

[R1]interface Tunnel 0/0/0
[R1-Tunnel0/0/0]ip add 192.168.4.1 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
[R3]interface Tunnel 0/0/0
[R3-Tunnel0/0/0]ip add 192.168.4.2 24
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp
[R3-Tunnel0/0/0]source s4/0/0
[R3-Tunnel0/0/0]nhrp entry 192.168.4.1 12.1.1.1 register
[R3-Tunnel0/0/0]nhrp network-id 100
[R4]interface Tunnel 0/0/0
[R4-Tunnel0/0/0]ip add 192.168.4.3 24
[R4-Tunnel0/0/0]tunnel-protocol gre p2mp
[R4-Tunnel0/0/0]source s4/0/0
[R4-Tunnel0/0/0]nhrp entry 192.168.4.1 12.1.1.1 register
[R4-Tunnel0/0/0]nhrp network-id 100

5. 内网使用RIP获取路由

[R1]rip
[R1-rip-1]version 2
[R1-rip-1]network 192.168.1.0
[R1-rip-1]network 192.168.4.0
[R1-Tunnel0/0/0]undo rip split-horizon

[R3]rip
[R3-rip-1]version 2
[R3-rip-1]network 192.168.4.0
[R3-rip-1]network 192.168.2.0

[R4]rip
[R4-rip-1]version 2
[R4-rip-1]network 192.168.4.0
[R4-rip-1]network 192.168.3.0

6.测试三个内网是否可以互相访问
