海量资料 超值下载配置PPP一、实验目的1.掌握广域网PPP封装配置2.理解DCE,DTE3.理解封装匹配二、实验描述1.企业环境中异地的互连通常要经过第三方的网络，比如网通，电信等。2.广域网通常需要收费，带宽比较有限，可靠行较低。三、实验拓扑四、实验设备1.R2801 2台2.串口线 1根五、实验步骤第1步：配置接口Router-A#config tRouter-A(config)#hostname Route-ARoute-A(config)#interface s1/1 Route-A(config-if)#ip address 192.168.1.1 255.255.255.0Route-A(config-if)#encapsulation ppp封装PPP协议Route-A(config-if)#clock rate 64000Route-A(config-if)#no shutdown第2步：查看接口配置Route-A#show interface serial 1/1Serial1/1 is up, line protocol is down 对端没有配置PPP封装，因此DOWN(disabled) Hardware is HD64570 Internet address is 192.168.1.1/24 MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, rely 255/255, load 1/255 Encapsulation PPP接口封装模式PPP, loopback not set, keepalive set (10 sec) LCP Closed Closed: LEXCP, BRIDGECP, IPCP, CCP, CDPCP, LLC2, BACP Last input never, output never, output hang never Last clearing of show interface counters never Input queue: 0/75/0 (size/max/drops); Total output drops: 0 Queueing strategy: weighted fair Output queue: 0/1000/64/0 (size/max total/threshold/drops) Conversations 0/0/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated)第3步：Router-B的配置Router-B#config tRouter-B(config)#hostname Route-BRoute-B(config)#interface s1/0 Route-B(config-if)#ip address 192.168.1.2 255.255.255.0Route-B(config-if)#encapsulation pppRoute-B(config-if)#no shutdown第4步：查看接口配置Router#show interface serial1/0Serial1/0 is up, line protocol is up (connected) Hardware is HD64570 Internet address is 192.168.1.2/24 MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, rely 255/255, load 1/255 Encapsulation PPP, loopback not set, keepalive set (10 sec) LCP Open Open: IPCP, CDPCP Last input never, output never, output hang never Last clearing of show interface counters never Input queue: 0/75/0 (size/max/drops); Total output drops: 0 Queueing strategy: weighted fair Output queue: 0/1000/64/0 (size/max total/threshold/drops) Conversations 0/0/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) 5 minute input rate 0 bits/sec, 0 packets/sec测试连通性：Route-A#ping 192.168.1.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:!Success rate is 100 percent (5/5), round-trip m
