一、实验拓扑
二、实验要求
- 1、R4为ISP，其上只能配置IP地址，R4与其他所有直连设备间均使用公有IP
- 2、R3-R5/6/7为MGRE环境，R3为中心站点;
- 3、整个0SPF环境IP基于172.16.0.0/16划分;
- 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
三、实验思路
首先我们来规划网段
172.16.0.0/16，这里我们首先规划需要配置多少个网段
由拓扑图可知：
共有四个区域以及一个单独使用RIP协议
所以，我们首先划分四个网段给各个区域 --- 所以说这里我们向后借3位
172.16.0.0/19 --- area 0
172.16.32.0/19 --- area 1
172.16.64.0/19 --- area 2
172.16.96.0/19 --- area 3
172.16.128.0/19 --- area 4
172.16.160.0/19 --- rip
172.16.192.0/19 --- 保留地址
172.16.224.0/19
接下来我们在不同区域内再次进行划分
172.16.0.0/19 --- area 0
172.16.0.0/24 --- p2p骨干
172.16.0.0/30

5、修改网络类型
由于创建的MGRE环境是一个P2P类型，所以无法和其他路由器建立邻居关系，我们需要修改它的网络类型

[R12-ospf-1]area 2
[R12-ospf-1-area-0.0.0.2]nssa
9、配置NAT环境
R3：
[R3]acl 2000
[R3-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[R3-acl-basic-2000]q

[R3-Serial4/0/0]nat outbound 2000
R5：
[R5]acl 2000
[R5-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[R5-acl-basic-2000]q

[R6-acl-basic-2000]q
[R6]int s 4/0/0
[R6-Serial4/0/0]nat outbound 2000
10、加快收敛
减少计时器时间
R3：
[R3]int t 0/0/0
[R3-Tunnel0/0/0]ospf timer hello 5
R5：
[R5]int t 0/0/0
[R5-Tunnel0/0/0]ospf timer hello 5
R6：

[R6-Tunnel0/0/0]ospf timer hello 5
R7：
[R7]int t 0/0/0
[R7-Tunnel0/0/0]ospf timer hello 5
11、配置接口认证
R1：
[R1]ospf 1
[R1-ospf-1]area 1
[R1-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher 123456
R2：
