配置 OSPF 特殊區域

配置 OSPF 特殊區域

6.1 問題

如圖，配置裝置 IP 位址和 OSPF 區域

R6 與 R7 之間不運作 OSPF，通過靜态路由互通

區域 12 沒有外部路由

確定 PC-1 與 PC-3 可以互通

import-route static //引入靜态路由

default-route-advertise //引入預設路由

6.2 方案

搭建實驗環境，如圖-6所示。

圖-6

6.3 步驟

實作此案例需要按照如下步驟進行。

1）配置IP位址，設定OSPF區域

2）配置 R6 與 R7 之間的互通路由，并引入 OSPF

[R6]ospf 1 router-id 6.6.6.6
[R6-ospf-1]import-route static //引入靜态路由，pc1才可平通pc3
[R6-ospf-1]area 56    
[R6-ospf-1-area-0.0.0.56]network  192.168.67.0 0.0.0.255
[R6-ospf-1-area-0.0.0.56]quit
           

3）配置區域12 為特殊區域

[R1]ospf 1
[R1-ospf-1]area 12    
[R1-ospf-1-area-0.0.0.12]stub
[R1-ospf-1-area-0.0.0.12]quit
[R2]ospf 1
[R2-ospf-1]area 12    
[R2-ospf-1-area-0.0.0.12]stub
[R2-ospf-1-area-0.0.0.12]quit
           

3）確定PC-1/2 與 PC3之間的互通
