目录
要求
确定广播域的个数
分配网段
配置路由器IP地址-优先公网配通
配置MGRE部分
拓扑结构:
要求
1、R4为ISP,其上只能配置IP地址,R4与其他所有直连设备间使用公有IP
2、R3~R5/6/7为MGRE环境,R3为中心站点
3、整个OSPF环境IP地址为172.6.0.0/16
4、所有设备均可访问R4的环回
5、减少LSA的更新量,加快收敛,保障更新安全
6、全网可达
使用的设备:12台路由器、1台交换机
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24个网段,包括13个环回网段和11个接口网段。但是,本次实验采用新的思想划分网络,即每个区域划分一个子网,共6个区域,为6个大子网,剩下的在区域内基于区域内的实际情况进行划分。公网的地址自己给。
分配网段
所有网段基于172.168.1.0/16进行划分,要划分出6个子网借3位掩码作为网络位
area0:172.16.0.0/19
每一个环回可能模拟50个用户,所以我们划分为
172.16.0.0/25、172.16.0.128/25、172.16.1.0/25、172.16.1.128/25一直到172.16.31.128/25
然后接口网段P2P: 172.16.0.0/25 划分为172.16.0.0/30、172.16.0.4/30、172.16.0.8/30、172.16.0.12/30......
MA网段:172.16.0.128/29、172.16.0.136/29、172.16.0.144/29......
注:这是一种全新的地址划分思路,所以以下的地址都是按照area0的样例划分的
172.16.0.0/29
172.16.0.128/25
172.16.1.0/25
172.16.1.128/25
area1:172.16.32.0/19
172.16.32.0/29
172.16.32.128/25
172.16.33.0/25
172.16.33.128/25
area2:172.16.64.0/19
172.16.64.0/30
172.16.64.4/30
172.16.64.128/25
area3:172.16.96.0/19
172.16.96.0/30
172.16.96.4/30
172.16.96.128/25
area4:172.16.128.0/19
172.16.128.0/30
172.16.128.128/25
172.16.129.0/25
EIGRP(RIP):172.16.160.0/19
172.16.160.0/25
172.16.160.128/25
备用地址:
172.16.192.0/19
172.16.224.0/19
公网地址:
10.1.1.0/24
20.1.1.0/24
30.1.1.0/24
40.1.1.0/24
和AR4的环回3.3.3.0/24
配置路由器IP地址-优先公网配通
以下的实际操作,先将R3、R4、R5、R6、R7公网配置,对他们优先进行IP地址的配置和MGRE配置并配置缺省路由,然后再配置其他的路由!!!

此时配置了MGRE的设备之间可以相互通信,但是除了MGRE之外都不能通信,还得运行OSPF协议
