前言

上節，介紹了OSPF的多區域和末梢區域，這一節簡單給各位介紹下配置。

一、簡單實驗題

二、簡單OSPF配置

1、先配置各個路由端口的基本配置

<Huawei>u t m Info: Current terminal monitor is off. <Huawei>sys Enter system view, return user view with Ctrl+Z.

2、配置OSPF

[R1]ospf 1 [R1-ospf-1]area 1 [R1-ospf-1-area-0.0.0.1]net 1.1.1.1 0.0.0.0 [R1-ospf-1-area-0.0.0.1]net 12.0.0.0 0.0.0.255 [R1-ospf-1-area-0.0.0.1]q [R1-ospf-1]q [R2]ospf 1 [R2-ospf-1]area 0 [R2-ospf-1-area-0.0.0.0]net 23.0.0.0 0.0.0.255 [R2-ospf-1-area-0.0.0.0]net 2.2.2.2 0.0.0.0 [R2-ospf-1-area-0.0.0.0]q [R2-ospf-1]area 1 [R2-ospf-1-area-0.0.0.1]net 12.0.0.0 0.0.0.255 [R2-ospf-1-area-0.0.0.1]q [R2-ospf-1]q [R3]ospf 1 [R3-ospf-1]area 0 [R3-ospf-1-area-0.0.0.0]net 23.0.0.0 0.0.0.255 [R3-ospf-1-area-0.0.0.0]net 34.0.0.0 0.0.0.255 [R3-ospf-1-area-0.0.0.0]net 3.3.3.3 0.0.0.0 [R3-ospf-1-area-0.0.0.0]q [R3-ospf-1]q [R4]ospf 1 [R4-ospf-1]area 0 [R4-ospf-1-area-0.0.0.0]net 34.0.0.0 0.0.0.255 [R4-ospf-1-area-0.0.0.0]net 4.4.4.4 0.0.0.0 [R4-ospf-1-area-0.0.0.0]q [R4-ospf-1]area 2 [R4-ospf-1-area-0.0.0.2]net 45.0.0.0 0.0.0.255 [R4-ospf-1-area-0.0.0.2]q [R4-ospf-1]q [R5]ospf 1 [R5-ospf-1]area 2 [R5-ospf-1-area-0.0.0.2]net 45.0.0.0 0.0.0.255 [R5-ospf-1-area-0.0.0.2]net 56.0.0.0 0.0.0.255 [R5-ospf-1-area-0.0.0.2]net 5.5.5.5 0.0.0.0 [R5-ospf-1-area-0.0.0.2]q [R5-ospf-1]q [R6]ospf 1 [R6-ospf-1]area 2 [R6-ospf-1-area-0.0.0.2]net 56.0.0.0 0.0.0.255 [R6-ospf-1-area-0.0.0.2]net 6.6.6.6 0.0.0.0 [R6-ospf-1-area-0.0.0.2]q [R6-ospf-1]q

3、路由表及連通性（以R1為例）

記得需要等一段時間，因為配置完OSPF后，需要進行選舉DR、BDR等一系列通信，大概十秒左右就行

[R1]dis ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: PublicDestinations : 17 Routes : 17 Destination/Mask Proto Pre Cost Flags NextHop Interface1.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack02.2.2.2/32 OSPF 10 1 D 12.0.0.2 GigabitEthernet 0/0/03.3.3.3/32 OSPF 10 2 D 12.0.0.2 GigabitEthernet 0/0/04.4.4.4/32 OSPF 10 3 D 12.0.0.2 GigabitEthernet 0/0/05.5.5.5/32 OSPF 10 4 D 12.0.0.2 GigabitEthernet 0/0/06.6.6.6/32 OSPF 10 5 D 12.0.0.2 GigabitEthernet 0/0/012.0.0.0/24 Direct 0 0 D 12.0.0.1 GigabitEthernet 0/0/012.0.0.1/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/012.0.0.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/023.0.0.0/24 OSPF 10 2 D 12.0.0.2 GigabitEthernet 0/0/034.0.0.0/24 OSPF 10 3 D 12.0.0.2 GigabitEthernet 0/0/045.0.0.0/24 OSPF 10 4 D 12.0.0.2 GigabitEthernet 0/0/056.0.0.0/24 OSPF 10 5 D 12.0.0.2 GigabitEthernet 0/0/0127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0[R1]ping -a 1.1.1.1 6.6.6.6PING 6.6.6.6: 56 data bytes, press CTRL_C to breakReply from 6.6.6.6: bytes=56 Sequence=1 ttl=251 time=70 msReply from 6.6.6.6: bytes=56 Sequence=2 ttl=251 time=60 msReply from 6.6.6.6: bytes=56 Sequence=3 ttl=251 time=60 msReply from 6.6.6.6: bytes=56 Sequence=4 ttl=251 time=40 msReply from 6.6.6.6: bytes=56 Sequence=5 ttl=251 time=40 ms--- 6.6.6.6 ping statistics ---5 packet(s) transmitted5 packet(s) received0.00% packet lossround-trip min/avg/max = 40/54/70 ms

三、 末梢區域配置

1、配置

上面我們看到了簡單的OSPF多區域配置，這個時候，我們把區域1的R1改成末梢配置，其他區域配置不變再看一下，

[R1]ospf 1 [R1-ospf-1]area 1 [R1-ospf-1-area-0.0.0.1]net 1.1.1.1 0.0.0.0 [R1-ospf-1-area-0.0.0.1]net 12.0.0.0 0.0.0.255 [R1-ospf-1-area-0.0.0.1]stub [R1-ospf-1-area-0.0.0.1]q [R1-ospf-1]q

因為R2是ABR，R1的變更信息需要ABR進行宣告，所以也得配置

[R2]ospf 1 [R2-ospf-1]area 0 [R2-ospf-1-area-0.0.0.0]net 23.0.0.0 0.0.0.255 [R2-ospf-1-area-0.0.0.0]net 2.2.2.2 0.0.0.0 [R2-ospf-1-area-0.0.0.0]q [R2-ospf-1]area 1 [R2-ospf-1-area-0.0.0.1]net 12.0.0.0 0.0.0.255 [R2-ospf-1-area-0.0.0.1]stub [R2-ospf-1-area-0.0.0.1]q [R2-ospf-1]q

2、連通性及路由表

我們看下R1的路由表和連通性

[R1]dis ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: PublicDestinations : 18 Routes : 18 Destination/Mask Proto Pre Cost Flags NextHop Interface0.0.0.0/0 OSPF 10 2 D 12.0.0.2 GigabitEthernet 0/0/01.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack02.2.2.2/32 OSPF 10 1 D 12.0.0.2 GigabitEthernet 0/0/03.3.3.3/32 OSPF 10 2 D 12.0.0.2 GigabitEthernet 0/0/04.4.4.4/32 OSPF 10 3 D 12.0.0.2 GigabitEthernet 0/0/05.5.5.5/32 OSPF 10 4 D 12.0.0.2 GigabitEthernet 0/0/06.6.6.6/32 OSPF 10 5 D 12.0.0.2 GigabitEthernet 0/0/012.0.0.0/24 Direct 0 0 D 12.0.0.1 GigabitEthernet 0/0/012.0.0.1/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/012.0.0.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/023.0.0.0/24 OSPF 10 2 D 12.0.0.2 GigabitEthernet 0/0/034.0.0.0/24 OSPF 10 3 D 12.0.0.2 GigabitEthernet 0/0/045.0.0.0/24 OSPF 10 4 D 12.0.0.2 GigabitEthernet 0/0/056.0.0.0/24 OSPF 10 5 D 12.0.0.2 GigabitEthernet 0/0/0127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0[R1]ping -a 1.1.1.1 6.6.6.6PING 6.6.6.6: 56 data bytes, press CTRL_C to breakReply from 6.6.6.6: bytes=56 Sequence=1 ttl=251 time=40 msReply from 6.6.6.6: bytes=56 Sequence=2 ttl=251 time=40 msReply from 6.6.6.6: bytes=56 Sequence=3 ttl=251 time=40 msReply from 6.6.6.6: bytes=56 Sequence=4 ttl=251 time=50 msReply from 6.6.6.6: bytes=56 Sequence=5 ttl=251 time=30 ms--- 6.6.6.6 ping statistics ---5 packet(s) transmitted5 packet(s) received0.00% packet lossround-trip min/avg/max = 30/40/50 ms

3、變化

這時候我們發現，R1的路由表例多出了一條默認的0.0.0.0的路由，連通性沒有變化，依然可以通信。

四、 完全末梢區域配置

1、配置

這次我們來了解下完全末梢區域，依然是只改動區域1的路由配置。
首先，因為R2是ABR，R1的變更信息需要ABR進行宣告，所以我們配置R2來宣告R1的完全末梢區域

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

2、查看R1的連通性及路由表

[R1]dis ip routing-table Route Flags: R - relay, D - download to fib ------------------------------------------------------------------------------ Routing Tables: PublicDestinations : 9 Routes : 9 Destination/Mask Proto Pre Cost Flags NextHop Interface0.0.0.0/0 OSPF 10 2 D 12.0.0.2 GigabitEthernet 0/0/01.1.1.1/32 Direct 0 0 D 127.0.0.1 LoopBack012.0.0.0/24 Direct 0 0 D 12.0.0.1 GigabitEthernet 0/0/012.0.0.1/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/012.0.0.255/32 Direct 0 0 D 127.0.0.1 GigabitEthernet 0/0/0127.0.0.0/8 Direct 0 0 D 127.0.0.1 InLoopBack0127.0.0.1/32 Direct 0 0 D 127.0.0.1 InLoopBack0 127.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0[R1]ping -a 1.1.1.1 6.6.6.6PING 6.6.6.6: 56 data bytes, press CTRL_C to breakReply from 6.6.6.6: bytes=56 Sequence=1 ttl=251 time=30 msReply from 6.6.6.6: bytes=56 Sequence=2 ttl=251 time=40 msReply from 6.6.6.6: bytes=56 Sequence=3 ttl=251 time=40 msReply from 6.6.6.6: bytes=56 Sequence=4 ttl=251 time=40 msReply from 6.6.6.6: bytes=56 Sequence=5 ttl=251 time=40 ms--- 6.6.6.6 ping statistics ---5 packet(s) transmitted5 packet(s) received0.00% packet lossround-trip min/avg/max = 30/38/40 ms

3、變化

我們可以發現，R1路由表例的其他路由不見了，但是多了一條0.0.0.0的默認路由，這就是LSA3里只剩下一條默認路由，LS3的其他都沒有了，但是通信完全沒問題。

五、總結

OSPF有其特別的用處，對以后的學習很重要，大家需要好好學習，明天或者今天趕更繼續更新OSPF的重要一章節：虛鏈路。
