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

四、实验步骤
1、配置接口IP地址以及环回（以此类推）
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]sys R1
[R1]user-interface console 0
[R1-ui-console0]idle-timeout 0 0
[R1-ui-console0]quit
[R1]int l0
[R1-LoopBack0]ip add 172.16.34.1 24
[R1-LoopBack0]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 172.16.33.1 24
[R1-GigabitEthernet0/0/0]quit
[R1]
2、配置缺省路由（依次类推r3,r5,r6,r7）
[R3]ip route-static 0.0.0.0 0 12.1.1.2
3、配置MGRE环境（以此类推r3,r5,r6,r7）
[R3]int t0/0/0
[R3-Tunnel0/0/0]ip address 172.16.1.1 29
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp
[R3-Tunnel0/0/0]source 12.1.1.1
[R3-Tunnel0/0/0]nhrp network-id 100
[R3-Tunnel0/0/0]nhrp entry multicast dynamic
[R3-Tunnel0/0/0]quit
[R3]
4、配置OSPF
[R1]ospf 1 router-id 1.1.1.1

[R5]ospf 1 router-id 5.5.5.5
[R5-ospf-1]area 0
[R5-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255
[R6]ospf 1 router-id 6.6.6.6
[R6-ospf-1]area 0
[R6-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.3.255
[R6-ospf-1-area-0.0.0.0]q
[R6-ospf-1]area 2

[R12]rip 1
[R12-rip-1]version 2
[R12-rip-1]network 172.16.0.0
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
[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]ospf network-type p2mp
[R5]int Tunnel 0/0/0
[R5-Tunnel0/0/0]ospf network-type p2mp
[R6]int Tunnel 0/0/0
[R6-Tunnel0/0/0]ospf network-type p2mp
[R7]int Tunnel 0/0/0
[R7-Tunnel0/0/0]ospf network-type p2mp
6、重发布
[R12]ospf 1
[R12-ospf-1]import-route rip 1
[R9]ospf 1
[R9-ospf-1]import-route ospf 2
7、配置汇总空接口防环

[R7]ip route-static 172.16.96.0 19 NULL 0
[R9]ospf 1
[R9-ospf-1]asbr-summary 172.16.128.0 255.255.224.0
[R9]ip route-static 172.16.128.0 19 NULL 0
[R12]ospf 1
[R12-ospf-1]asbr-summary 172.16.160.0 255.255.224.0
[R12]ip route-static 172.16.160.0 19 NULL 0
8、配置特殊区域：

[R1-ospf-1-area-0.0.0.1]stub
[R2]ospf 1
[R2-ospf-1]area 1
[R2-ospf-1-area-0.0.0.1]stub

[R6]ospf 1
[R6-ospf-1]area 2
[R6-ospf-1-area-0.0.0.2]nssa no-summary
[R7]ospf 1
[R7-ospf-1]area 3
[R7-ospf-1-area-0.0.0.3]nssa no-summary
[R8]ospf 1
[R8-ospf-1]area 3
[R8-ospf-1-area-0.0.0.3]nssa

[R12]ospf 1
[R12-ospf-1]area 2
[R12-ospf-1-area-0.0.0.2]nssa
9、配置NAT环境
[R3]acl 2000
[R3-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[R3-acl-basic-2000]q
[R3]int Serial 4/0/0
[R3-Serial4/0/0]nat outbound 2000
[R5]acl 2000
[R5-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[R5-acl-basic-2000]q
[R5]int Serial 4/0/0
[R5-Serial4/0/0]nat outbound 2000
[R7]acl 2000
[R7-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[R7-acl-basic-2000]q
[R7]int g 0/0/0

10、加快收敛（依次类推r3,r5,r6,r7）
[R3]int t 0/0/0
[R3-Tunnel0/0/0]ospf timer hello 5
11、配置接口认证
