验证ARP学习功能

3.5.1验证ARP功能验证ARP功能使用设备：（1）路由器；（2）交换机；（3）pc机。测试组网：测试编号3.5.1验证ARP功能;测试组：验证ARP功能；测试项目：ARP;测试目的：验证ARP功能；测试步骤：1、 搭建拓扑结构图；2、 配置基本命令；3、 验证arp功能；预期测试结果：可以查看到ARP的基本功能。测试准备：路由器，交换机，pc机测试说明：验证ARP功能；测试结果：（1）、清楚pc机的arp缓存；11112-^DocumentsandSettings\Administratorharp-d2-^DocumentsandSettings\Administrator>arp-a4oARPEntriesFound（2）、pingPC2地址；C：\DocumentsandSettingsMldministFatop>ping192-1G8-2-10Pinging192-1G8-2-10uith32bytesofdata：fromRepl^rfromEepl^rfrom0=0=0：fromRepl^rfromEepl^rfrom0=0=0：l>5ftes=32hiftes=32bi;tes=32Repli/from0：biftes=32time=118nsTTL=127time=12msTTL=127time=21n)3TTL=127time=15msTTL=127Fingstatisticsfor192.168-2-IS：Packets:Sent=4,Receiued=4,Lost=0<0zloss^,Approximateroundtriptinesinmilli-seconds:Frame48:60bytesonwire(480bits)sFrame48:60bytesonwire(480bits)s60bytescaptured(480bits)(3)、抓获报文；4/39.39UUUU；UU：LLL；_L3；UU：UUCZ:UU:U±:XO:UU: OUKtpiy4863.090000DIAB_O3：OO：O1BroadcastARP60Whohas?Tell0 !4963.133000c2:00:01:18:00:00DIAB_03:00:01|ARP60isatc200:01:18:00:005063.1330000074Echo(ping)requestid=0x0200,seq=45312/177,tt1=1285163.15800000ICMP74Echo(ping)replyid=0x0200,seq=45312/177,rt1=1275264.09500000ICMP74Echo(ping)requestid=OxO2OO,seq=45568/178,ttl=1285364.10800000ICMP74Echo(ping)replyid=OxO2OO,seq=45568/178,ttl=127SEthernetII,Src:DIAB_0B:00:01(00:00:20:03:00:01),Dst:Broadcast(ff:ff:ff:ff:ff:ff)0Destination:Broadcast(ff:ff:ff:ff:ff:ff田Source:DIAB_7??TO??^7q??TO?20?03?0Q?0^|Type:Padding:000000000000000000000000000000000000QAddressResolufionProtocol(request)Hardwaretype:Ethernet(1)Protocoltype:IP(0x0800)Hardwaresize:6Protocolsize:4opcode:request(1)SenderMACaddress:DIAB_0B:00:01 ::20:03:□□:01)SenderIPaddress:0(192.16S.1.10)TargetMACaddress:00:00:00_00:00:00(00:00:00:00:00:00)TargetIPaddress:()(4)、查看PC1的arp缓存表;C:\DocumentsandSettingsSfidministrator：arp-aInterface:0 0x10003InternetAddress PhysicalAddress Type c2-00-01-18-00-00 dynamic验证ARP代理功能:测试组网：

ARP代理功能：测试组:ARP;测试项目：验证ARP代理功能；测试目的:验证ARP代理功能；测试步骤:1、 搭建号拓扑图；2、 将路由器的接口和pc机的ip地址配好；不需要配置网关；3、 C1分别pingpc4/pc2/pc3,并在路由器相应的接口抓包；4、 总结ping过程。预期测试结果：代理ARP的基本功能都能查看到。测试准备：交换机，路由器，pc机；测试结果:（1）因为cisco的路由器默认开启了代理ARP所以我们先关掉代理ARP.broadcast,forv?ardingisdisabled
