帧中继更具体配置信息

一、点到点：
点对点帧中继配置时，需注意：
（DLCI）数据链路标识符要“有来有回”也就是说数据就像在一个
管道中流动不能只想一个方向流动,这样的话就达不到通信的效果了，
所以，要双向流动（即：（DLCI）数据链路标识符要“有来有回”）;
另外,在来回的两个端口ip地址需要在同一个网段；

 

路由器R1配置信息：
第一步进入物理接口，该封装，设置时钟速率，并启动：
R1(config)#interface serial 0/0/1
R1(config-if)#encapsulation frame-relay
R1(config-if)#clock rate 128000
R1(config-if)#no shutdown

第二步进入子接口，设置为点对点模式：
R1(config)#interface serial 0/0/1.1 point-to-point

第三步配置子接口ip地址：
R1(config-subif)#ip address 10.1.3.1 255.255.255.0

第四步进行端口地址映射：

R1(config-subif)#frame-relay interface-dlci 103
R1(config-subif)#exit
以下重复二、三、四步：
R1(config)#interface serial 0/0/1.2 point-to-point

R1(config-subif)#ip address 10.1.5.1 255.255.255.0

R1(config-subif)#frame-relay interface-dlci 105

R1(config-subif)#end
%SYS-5-CONFIG_I: Configured from console by console
R1#ping 10.1.3.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.3.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 46/53/63 ms

路由器R3配置信息：

R3(config)#interface serial 0/0/0

R3(config-if)#encapsulation frame-relay

R3(config-if)#clock rate 128000

R3(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up
R3(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state to up
R3(config-if)#exit
R3(config)#

R3(config)#interface serial 0/0/0.1 point-to-point

R3(config-subif)#ip address 10.1.3.2 255.255.255.0

R3(config-subif)#frame-relay interface-dlci 301
R3(config-subif)#exit
R3(config)#

R3(config)#interface serial 0/0/0.2 point-to-point

R3(config-subif)#ip address 10.3.5.1 255.255.255.0

R3#ping 10.1.3.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.3.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 62/62/63 ms

路由器R5配置信息：

Router(config)#interface serial 0/0/0

Router(config-if)#encapsulation frame-relay

Router(config-if)#clock rate 128000

Router(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up
Router(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state to up
Router(config-if)#ex
Router(config)#

Router(config)#interface serial 0/0/0.1 point-to-point

Router(config-subif)#ip address 10.1.5.2 255.255.255.0

Router(config-subif)#frame-relay interface-dlci 501
Router(config-subif)#exit
Router(config)#

Router(config)#interface serial 0/0/0.2 point-to-point

Router(config-subif)#ip address 10.3.5.2 255.255.255.0

Router(config-subif)#frame-relay interface-dlci 503
Router(config-subif)#end
%SYS-5-CONFIG_I: Configured from console by console
Router#ping 10.3.5.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.3.5.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 125/128/141 ms

 

二、点到多点：
点到多点帧中继配置较简单：

仍需注意，数据流是有去有回的！！！

路由器R3配置信息：
第一步同样进入物理接口改封装，设速率，启动：

R3(config)#interface serial 0/1/1

R3(config-if)#encapsulation frame-relay

R3(config-if)#clock rate 128000

R3(config-if)#no shutdown

R3(config-if)#ex
R3(config)#

第二步进入逻辑接口，并设置其为点到多点模式，并设置好ip地址：
R3(config)#interface serial 0/1/1.1 multipoint

R3(config-subif)#ip address 172.16.134.3 255.255.255.0
第三步地址映射
R3(config-subif)#frame-relay map ip 172.16.134.1 103
R3(config-subif)#frame-relay map ip 172.16.134.2 104
R3(config-subif)#end
%SYS-5-CONFIG_I: Configured from console by console
R3#ping 172.16.134.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.134.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 62/62/63 ms

R3#ping 172.16.134.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.134.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 62/62/63 ms
