OSPF综合实验
IP规划
ospf和RIP分两个网段:
172.16.0.0/17 -- ospf
172.16.128.0/17 -- rip
ospf五个区域:
172.16.0.0/20 -- area 0
172.16.16.0/20 -- area 1
172.16.32.0/20 -- area 2
172.16.48.0/20 -- area 3
172.16.64.0/20 -- area 4
172.16.96.0/20
area 0 :链路,3个路由器的环回。4个网段:直接划到24,预留网段
172.16.1.0/24 -- R5环回
172.16.2.0/24 -- R6环回
172.16.3.0/24 -- R7环回
...
链路网段为34.1.1.1 。。。这样
MGRE:
tunnel ip:
100.1.1.3
100.1.1.5
...
area 1 :同area0一样
172.16.16.0/24 --链路(接口)网段
172.16.17.0/24 -- R1环回
172.16.18.0/24 -- R2环回
172.16.19.0/24 -- R3环回
area 2:1个环回+2段链路
172.16.32.0/24 --R6-R11
172.16.33.0/24 -- R11-R12
172.16.34.0/24 -- R11 环回
area 3:1个环回+2段链路
172.16.48.0/24 -- R7-R8
172.16.49.0/24 -- R8-R9
172.16.50.0/24 -- R8环回
area 4:2个环回+1段链路
172.16.64.0/24 -- R9 环回
172.16.65.0/24 -- R10 环回
172.16.66.0/24 -- R9-R10
RIP:
172.16.128.0/17
2个环回:
172.16.128.0/18
172.16.192.0/18

全网互通
R9
双向重发布解决:
[r9-ospf-2]import-route ospf 1
[r9-ospf-1]import-route ospf 2
R12
[r12-ospf-1]import-route rip 1
[r12-rip-1]import-route ospf 1
汇总 ,特殊区域
在IP规划时,咱们给区域划分好网段了,所以直接配就好
R3
在边界路由器上设置汇总:
[r3-ospf-1-area-0.0.0.1]abr-summary 172.16.16.0 255.255.240.0
做Totally stub。给R1,R2做stub
[r1-ospf-1-area-0.0.0.1]stub
[r2-ospf-1-area-0.0.0.1]stub
[r3-ospf-1-area-0.0.0.1]stub no-summary
R6
[r6-ospf-1-area-0.0.0.2]abr-summary 172.16.32.0 255.255.240.0
R6:Totally NSSA
[r6-ospf-1-area-0.0.0.2]nssa no-summary
[r11-ospf-1-area-0.0.0.2]nssa
[r12-ospf-1-area-0.0.0.2]nssa
R7
[r7-ospf-1-area-0.0.0.3]abr-summary 172.16.48.0 255.255.240.0
R7:Totally NSSA
做完之后,R10上没有其他路由的信息,在r9上写条缺省
[r9-ospf-2]default-route-advertise
认证
区域认证:
像这样给每个区域认证
[r1-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher 123456
NAT
[r3-acl-basic-2000]rule permit source 172.16.16.0 0.0.15.255
