文章详细描述了如何配置R1、R3、R4构建全连接的MGRE环境，R1作为hub与R5、R6建立hub-spoke结构，同时使用OSPF保证全网可达，涉及IP地址、Tunnel协议和NHRP设置。

实验要求：

在这里插入图片描述

1，R1-R3-R4构建全连的MGRE环境

2，R1-R5-R6建立hub-spoke的MGRE环境，其中R1为中心

3，R1-R3…R6均存在环回网段模拟用户私网，使用OSPF使全网可达

4，其中R2为ISP路由器，仅配置IP地址

1.配置IP

[r1]int LoopBack 0
[r1-LoopBack0]ip address 192.168.1.1 24
[r1-LoopBack0]int g 0/0/0
[r1-GigabitEthernet0/0/0]ip address 12.0.0.1 24
[r1-GigabitEthernet0/0/0]int g 0/0/1
[r1-GigabitEthernet0/0/1]ip address 21.0.0.1 24

ISP

2.构建r1-r3-r4全连MGRE环境（配置缺省路由，保证公网联通，中心开启伪广播）

[r1]ip route-static 0.0.0.0 0 12.0.0.2

[r5-Tunnel0/0/0]source 25.0.0.1
[r5-Tunnel0/0/0]nhrp network-id 100
[r5-Tunnel0/0/0]nhrp entry 192.168.7.1 12.0.0.1 register 
[r5-Tunnel0/0/0]nhrp entry multicast dynamic 
[r5-Tunnel0/0/0]ip route-static 0.0.0.0 0 25.0.0.2

[r6]int Tunnel 0/0/0
[r6-Tunnel0/0/0]ip address 192.168.7.6 24
[r6-Tunnel0/0/0]tunnel-protocol gre p	
[r6-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r6-Tunnel0/0/0]source 26.0.0.1
[r6-Tunnel0/0/0]nhrp network-id 100
[r6-Tunnel0/0/0]nhrp entry 192.168.7.1 12.0.0.1 register 
[r6-Tunnel0/0/0]ip route-static 0.0.0.0 0 26.0.0.2

4.使用OSPF使全网可达
