ospf下幀中繼網絡配置

 一直想寫篇文章關于幀中繼這方面的，一來這東西是個難點二來網上這東西配置的都不咋完全，那小弟就獻醜了。廢話不說 看圖

<a target="_blank" href="http://blog.51cto.com/attachment/201010/233204129.png"></a>

我們用r2模拟幀中繼交換機

frame-relay s

enable

conf t

no ip domain-lookup

ip classless

ip subnet-zero

hostname r2

line cons 0

exec-timeout 0 0

logg sy

exit

int s0/0

no sh

en fr 

frame-relay lmi-type cisco   ||： lmi 類型

frame-relay intf-type dce               ：設為dce

frame-relay route 103 interface s0/1 301     ：靜态路由映射

frame-relay route 104 interface s0/2 401

clock rate 64000

int s0/1 

en fr

frame-relay lmi-type cisco

frame-relay intf-type dce

frame-relay route 301 interface s0/0 103

int s0/2

frame-relay route 401 interface s0/0 104

r1配置

hostname r1

ip add 192.168.1.1 255.255.255.0

r2配置

int s0/1

ip add 192.168.1.3 255.255.255.0

r4配置

ip add 192.168.1.4 255.255.255.0

這樣我們我們就完成了r1 2 3 4 基本配置  

在r2  r4#show frame-relay r

Input Intf      Input Dlci      Output Intf     Output Dlci     Status

Serial0/0       103             Serial0/1       301             inactive

Serial0/0       104             Serial0/2       401             inactive

Serial0/1       301             Serial0/0       103             inactive

Serial0/2       401             Serial0/0       104             inactive

我們再在r1上配置ospf

int loo 0

ip add 1.1.1.1 255.255.255.0 

ip ospf netw point to point

ip ospf netw b

ip ospf pri 10

frame-re map ip 192.168.1.3 103 b                 ：對端ip   自己的dlci     廣播類型

frame-re map ip 192.168.1.4 103 b

frame-re map ip 192.168.1.1 103     可以 ping 通自己

no frame-re inv

router ospf 1

router-id 1.1.1.1

netw 192168.1.0 0.0.0.255 area 0

netw  1.1.1.0 0.0.0.255 area 0

r3配置

ip add 3.3.3.3 255.255.255.0

ip ospf pri 

frame-relay map ip 192.168.1.1 301 b

frame-relay map ip 192.168.1.4 301 b

frame-relay map ip 192.168.1.3 301

netw 3.3.3.0 0.0.0.255 area 0

netw 192.168.1.0 0.0.0.255 area 0

router-id 3.3.3.3

int loop 0

ip add 4.4.4.4 255.255.255.0 

ip add 192.168.1.4 255.255.255.0 

frame-relay map ip 192.168.1.1 401 b

frame-relay map ip 192.168.1.3 401 b

frame-relay map ip 192.168.1.4 401

netw 4.4.4.0 0.0.0.255 area

router-id 4.4.4.4

我們測試下r4路由表

r4#show ip route 

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

     1.0.0.0/24 is subnetted, 1 subnets

O       1.1.1.0 [110/65] via 192.168.1.1, 00:28:02, Serial0/2

     3.0.0.0/24 is subnetted, 1 subnets

O       3.3.3.0 [110/65] via 192.168.1.3, 00:28:02, Serial0/2

     4.0.0.0/24 is subnetted, 1 subnets

C       4.4.4.0 is directly connected, Loopback0

C    192.168.1.0/24 is directly connected, Serial0/2

ping 1.1.1.1

r4#ping 1.1.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:

實驗完成！
