拓扑图

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OSPF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

实验思路

  1. 先划分172.16.0.0/16IP地址
  2. 再配置IP地址
  3. 公网通(缺省路由)
  4. 配置OSPF,RIP,路由引入RIP
  5. 配置MGRE,R3为中心站点,ospf宣告隧道
  6. 修改接口类型,取消选举
  7. 多进程重发布area4
  8. 配置easyIP
  9. 路由聚合(优化骨干),R3,5,6,7传入区域聚合,R9(进程1),12(ospf协议视图)ASBR聚合
  10. 设置特殊区域(优化非骨干区域),area1完全末梢,area3,area2完全非纯末梢,会自动下发缺省(能够访问R4环回)
  11. 加快收敛,修改Hello时间ospf timer hello 5
  12. 保证更新安全,区域认证

[R7-ospf-1-area-0.0.0.0]net 172.16.6.7 0.0.0.0

4. 修改接口类型,取消选举
R3:

[R3-Tunnel0/0/0]ospf network-type broadcast

R5:

[R5-Tunnel0/0/0]ospf network-type broadcast

[R5-Tunnel0/0/0]ospf dr    

[R5-Tunnel0/0/0]ospf dr-priority 0

R6:

[R6-Tunnel0/0/0]ospf network-type broadcast      

[R6-Tunnel0/0/0]ospf dr-priority 0

R7:

[R7-Tunnel0/0/0]ospf network-type broadcast

[R7-Tunnel0/0/0]ospf dr-priority 0

5. 多进程重发布area4
R9:

[R9-ospf-2]import-route ospf 1

[R9-ospf-1]import-route ospf 2

6. 配置easyIP
R3:

[R3]acl 2000

[R3-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255

[R3]int s 4/0/0

[R3-Serial4/0/0]nat outbound 2000

[R5-acl-basic-2000]q

[R5]int s 4/0/0

[R5-Serial4/0/0]nat outbound 2000

R6:

[R6]acl 2000

[R6-acl-basic-2000]rule 5 permit source 172.16.0.0 0.0.255.255

[R6]int s 4/0/0

[R6-Serial4/0/0]nat out 2000

R7:

[R7]acl 2000

[R7-acl-basic-2000]rule 5 permit source 172.16.0.0 0.0.255.255

[R7-acl-basic-2000]int g 0/0/0

[R7-GigabitEthernet0/0/0]nat outbound 2000

7. 路由聚合(优化骨干),R3,5,6,7传入区域聚合,R9(进程1),12(ospf协议视图)ASBR聚合
(1)ABR聚合:

R3:

[R3]ospf 1 router-id 3.3.3.3

[R3-ospf-1]area 1

[R3-ospf-1-area-0.0.0.1]abr-summary 172.16.32.0 255.255.224.0

R6:

[R6]ospf 1 router-id 6.6.6.6

[R6-ospf-1]area 2

[R6-ospf-1-area-0.0.0.2]abr-summary 172.16.64.0 255.255.224.0

R7:

[R7]ospf 1 router-id 7.7.7.7

[R7-ospf-1]area 3   

[R7-ospf-1-area-0.0.0.3]abr-summary 172.16.96.0 255.255.224.0

(2)ASBR聚合

R9:

[R9]ospf 1 router-id 9.9.9.9

[R9-ospf-1]asbr-summary 172.16.128.0 255.255.224.0

R12:

       [R12]ospf 1 router-id 12.12.12.12

[R12-ospf-1]asbr-summary 172.16.160.0 255.255.224.0
 

8. 设置特殊区域(优化非骨干区域),area1完全末梢,area3,area2完全非纯末梢,会自动下发缺省(就能够访问R4环回)

Area 1:

R1:

[R1-ospf-1-area-0.0.0.1]stub no-summary

R2:

[R2-ospf-1-area-0.0.0.1]stub no-summary

R3:

[R3-ospf-1-area-0.0.0.1]stub no-summary

Area 2:

R6:

[R6-ospf-1-area-0.0.0.2]nssa no-summary

R11:

[R11-ospf-1-area-0.0.0.2]nssa no-summary

R12:

[R12-ospf-1-area-0.0.0.2]nss no-summary

Area 3:

R7:

[R7-ospf-1-area-0.0.0.3]nssa no-summary

R8:

[R7-ospf-1-area-0.0.0.3]nssa no-summary

R9:

[R9-ospf-1-area-0.0.0.3]nssa no-summary

R1:

[R1-GigabitEthernet0/0/0]ospf timer hello 5

R2:

[R2-GigabitEthernet0/0/0]ospf timer hello 5

R3:

[R3-Tunnel0/0/0]ospf timer hello 5
