配置帧中继子接口和流量整形

第一步：在

R1(config-if)#en fr

在接口下封装帧中继

R1(config-if)#no fram

在子接口

S3/0.2

下配置

地址

R1(config-subif)#no sh

激活端口

配置

OSPF

路由协议

R2(config-router)#net

R2(config-router)#network 0.0.0.0 0.0.0.0 are

R2(config-router)#network 0.0.0.0 0.0.0.0 area 0

R2(config-router)#^Z

R2#

R2(config-if)#exit

R2(config)#

R2(config)#int s3/0

R2(config-if)#end

第三步：在

上的预配置

R3(config)#int s3/0

R3(config-if)#en fr

封装帧中继

R3(config-if)#no fra

S3/0.1

映射关系

R3(config-if)#exit

R3(config)#^Z

R3(config)#int s3/0

R3(config-if)#no sh

R3(config-if)#end

激活端口

R3#show ip

R3#conf

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with CNTL/Z.

R3(config)#int s3/0

R3(config-if)#end

R3#

00:18:09: %SYS-5-CONFIG_I: Configured from console by console

R3#conf

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with CNTL/Z.

R3(config)#

R3(config)#router osp

R3(config)#router ospf 64

R3(config-router)#net

R3(config-router)#network 0.0.0.0 0.0.0.0 area

R3(config-if)#ip ospf net

R3(config-if)#ip ospf network poin

R3(config-if)#ip ospf network point-to-p

R3(config-if)#^Z

第四步：用扩展

ping

命令测试路由之间的连通性，发送几个大数据包（超过

1000

字节的数据包），测试吞吐量，注意以毫秒计的返回时间

Protocol [ip]:

Target IP address: 192.168.12.2

Repeat count [5]: 55

Datagram size [100]: 1111

Timeout in seconds [2]:

Extended commands [n]: y

Source address or interface: 192.168.12.1

Type of service [0]:

Set DF bit in IP header? [no]:

Validate reply data? [no]:

Data pattern [0xABCD]:

Loose, Strict, Record, Timestamp, Verbose[none]:

Sweep range of sizes [n]:

Type escape sequence to abort.

Sending 55, 1111-byte ICMP Echos to 192.168.12.2, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Success rate is 100 percent (55/55), round-trip min/avg/max = 52/557/1120 m

第五步：在

进行

Frame-relay

流量整形

R1#conf

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with CNTL/Z.

R1(config)#

R1(config)#map-cla

R1(config)#map-class fram

R1(config)#map-class frame-relay cir

R1(config-map-class)#fram

R1(config-map-class)#frame-relay tra

R1(config-map-class)#frame-relay traffic-rate 19200

R1(config-map-class)#exit

R1(config)#int s3/0

R1(config-if)#fram

R1(config-if)#frame-relay tra

R1(config-if)#frame-relay traffi

R1(config-if)#frame-relay traffic-shaping

R1(config-if)#int s3/0.2

R1(config-subif)#fram

R1(config-subif)#frame-relay class

R1(config-subif)#frame-relay class cir

R1(config-subif)#^Z

第六步：在

上进行

Frame-relay

流量整形

R2(config)#map

R2(config)#map-cl

R2(config)#map-class fram

R2(config)#map-class frame-relay cir

R2(config-map-class)#fram

R2(config-map-class)#frame-relay traff

R2(config-map-class)#frame-relay traffic-rate 19200

R2(config-map-class)#exit

R2(config)#int s3/0

R2(config-if)#frame

R2(config-if)#frame-relay class cir

R2(config-if)#^Z

第七步：再次进行

ping
