OSPF-MGRE综合实验

article 2024/11/18 5:35:02

 拓扑结构：

 要求：

1、R6为ISP只能配置IP地址，R1~R5的环回为私有网段

2、R1/4/5为全连的MGRE结构，R1/2/3为星型的拓扑结构，R1为中心站点

3、所有私有网段可以互相通讯，私有网段使用OSPF协议完成

 使用的设备：6台路由器

解决网络拓扑：

1、确定广播域的个数

2、分配网段

3、配置IP地址 （优先配置路由器）

确定广播域的个数

根据拓扑结构图以及要求可知，本拓扑结构一共拥有9个网段，包括4个给定网段，一个环回网段和四个内网网段

分配网段

自主分配网段

192.168.0.0/24和10.1.1.0/8和15.1.1.0/24网段

 配置路由器IP地址

配置全连网状的MGRE，没有中心站点，双向注册

AR1：

[r1]interface Tunnel 0/0/1
[r1-Tunnel0/0/1]ip address 10.1.2.1 24
[r1-Tunnel0/0/1]tunnel-protocol gre p2mp 
[r1-Tunnel0/0/1]source 15.1.1.1

[r1]

AR4：

[r4-Tunnel0/0/0]nhrp entry 10.1.2.3 20.1.1.1 register
[r4-Tunnel0/0/0]q
[r4]

AR5：R4可以和R5进行通信，但是R5并不能向R4进行注册，所以需要在5上也开启伪广播

[r5]interface Tunnel 0/0/0
[r5-Tunnel0/0/0]ip address 10.1.2.3 24
[r5-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r5-Tunnel0/0/0]source GigabitEthernet 0/0/0
Apr 29 2023 21:38:10-08:00 r5 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP on the interface Tunnel0/0/0 has entered the UP state. 
[r5-Tunnel0/0/0]nhrp network-id 101
[r5-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register
[r5-Tunnel0/0/0]nhrp entry 10.1.2.2 19.1.1.1 register
Info: This peer protocol address conflicts with hub register peer protocol address.
[r5-Tunnel0/0/0]nhrp entry multicast dynamic
[r5-Tunnel0/0/0]q
[r5]

配置了MGRE之后，真实的拓扑结构

然后R1~R5的每一个路由器上都写上一条指向R6的静态缺省路由

[r1]ip route-static 0.0.0.0 0 16.1.1.2
[r1]ip route-static 0.0.0.0 0 15.1.1.2
[r2]ip route-static 0.0.0.0 0 17.1.1.2
[r3]ip route-static 0.0.0.0 0 18.1.1.2
[r4]ip route-static 0.0.0.0 0 19.1.1.2
[r5]ip route-static 0.0.0.0 0 20.1.1.2

此时配置了MGRE的设备之间可以相互通信，但是两个MGRE之间不能通信，还得运行OSPF协议

配置OSPF动态路由协议

配置OSPF动态路由协议，配置认证，保证更新安全

配置之后，全网可以正常相互访问

​

 

 并且都可以访问R6（isp）的环回，但是以ping -a 的命令指定他们访问R6环回的地址却访问不到R6的环回，这个问题暂时得不到解决。

 实验到此为止，就完成了 ，要求也是全部完成。
