寒假hcip作业二

给6个区域做地址规划
172.16.0.0/16

172.16.0.0/19 A0
骨干链路有两种 P2P——一个网段只有两个IP的需求 172.16.0.0/25
172.16.0.0/30——172.16.0.4/30~172.16.0.124/30
172.16.0.
MA网段节点数量不限定 172.16.0.128/25
172.16.0.128/29（area1和area0）——172.16.0.136/29~172.16.0.248/29
环回用：
172.16.1.0/25 172.16.1.128/25 172.16.2.0/25—— 172.16.31.128/25

172.16.32.0/19 A1
172.16.32.0/25—— P2P（一个网段只有两个IP需求） 172.16.32.128/29 ——MA网络
172.16.64.0/19 A2
172.16.96.0/19 A3
172.16.128.0/19 A4
172.16.160.0/19 RIP——注意RIP宣告只能宣告主类，后期会需要处理
172.16.160.0/20 172.16.176.0/20

172.16.192.0/19
192.16.224.0/19
取6个

1.拓扑图

2、规划IP，并给所有路由器均配置一个环回接口

[R1]int LoopBack 0
[R1-LoopBack0]ip address 172.16.33.1 25

[R2]int LoopBack 0
[R2-LoopBack0]ip address 172.16.33.129 25

[R3]int LoopBack 0
[R3-LoopBack0]ip address 172.16.34.1 25

[R4]int LoopBack 0
[R4-LoopBack0]ip address 4.4.4.4 24

[R5]int LoopBack 0
[R5-LoopBack0]ip address 172.16.1.1 25

[R6]int LoopBack 0
[R6-LoopBack0]ip address 172.16.1.129 25

[R7]int LoopBack 0
[R7-LoopBack0]ip address 172.16.2.1 25

[R8]int LoopBack 0
[R8-LoopBack0]ip address 172.16.97.1 25

[R9]int LoopBack 0
[R9-LoopBack0]ip address 172.16.129.1 25

[R10]int LoopBack 0
[R10-LoopBack0]ip address 172.16.129.129 25

[R12]int LoopBack 0
[R12-LoopBack0]ip address 172.16.160.1 20
[R12-LoopBack0]int lo1
[R12-LoopBack1]ip address 172.16.176.1 20

3.建R1/4/5为全连的MGRE结构，R1/R4/R5需要互相注册；在MGRE环境下，OSPF的默认工作方式为点到点，只能建立一个邻居，所以需要修改各个路由器的tunnel接口模式为broadcast

ip address 10.1.1.1 255.255.255.0
tunnel-protocol gre p2mp
source 16.1.1.1
ospf network-type broadcast
nhrp entry multicast dynamic
nhrp network-id 100
nhrp entry 10.1.1.4 46.1.1.1 register
nhrp entry 10.1.1.5 56.1.1.1 register

R4:interface Tunnel0/0/0
ip address 10.1.1.4 255.255.255.0
tunnel-protocol gre p2mp
source 46.1.1.1
ospf network-type broadcast
nhrp entry multicast dynamic
nhrp network-id 100
nhrp entry 10.1.1.1 16.1.1.1 register
nhrp entry 10.1.1.5 56.1.1.1 register

R5:interface Tunnel0/0/0
ip address 10.1.1.5 255.255.255.0
tunnel-protocol gre p2mp
source 56.1.1.1
ospf network-type broadcast
nhrp entry multicast dynamic
nhrp network-id 100
nhrp entry 10.1.1.1 16.1.1.1 register
nhrp entry 10.1.1.4 46.1.1.1 register

4.R1/2/3为星型的拓扑结构，R1为中心站点，R2/R3需要到R1注册，同样要切换接口工作方式为broadcast

R1：interface Tunnel0/0/1
    ip address 10.1.2.1 255.255.255.0
    tunnel-protocol gre p2mp
    source 16.2.2.1
    ospf network-type broadcast
    nhrp entry multicast dynamic
    nhrp network-id 101

R2：interface Tunnel0/0/1
    ip address 10.1.2.2 255.255.255.0
    tunnel-protocol gre p2mp
    source 26.2.2.1
    ospf network-type broadcast
    ospf dr-priority 0
    nhrp network-id 101
    nhrp entry 10.1.2.1 16.2.2.1 register

R3:interface Tunnel0/0/1
     ip address 10.1.2.3 255.255.255.0
     tunnel-protocol gre p2mp
     source 36.2.2.1
     ospf network-type broadcast
     ospf dr-priority 0
     nhrp network-id 101
     nhrp entry 10.1.2.1 16.2.2.1 register

5.ospf配置

R1：ospf 1 router-id 1.1.1.1
    area 0.0.0.0
    network 10.1.1.1 0.0.0.0
    network 10.1.2.1 0.0.0.0
    network 192.168.1.0 0.0.0.255

R2：ospf 1 router-id 2.2.2.2
    area 0.0.0.0
    network 10.1.2.2 0.0.0.0
    network 192.168.2.1 0.0.0.0

R3：ospf 1 router-id 3.3.3.3
    area 0.0.0.0
    network 10.1.2.3 0.0.0.0
    network 192.168.3.1 0.0.0.0

R4：ospf 1 router-id 4.4.4.4
   area 0.0.0.0
   network 10.1.1.4 0.0.0.0
   network 192.168.4.1 0.0.0.0

R5：ospf 1 router-id 5.5.5.5
     area 0.0.0.0
    network 10.1.1.5 0.0.0.0
    network 192.168.5.1 0.0.0.0
