換個法子看電影eNSP的組播功能模擬實(shí)驗(yàn).docx

一、下載eNSP和vlc播放器eNSP正式版本下載地址：/edownload/enterprise/download!download.action?contentId=SW1000002740&contentType=SOFT&partNo=2001VLC是開源軟件下載地址是：/vlc/download-windows.html二、安裝vlc播放器下載后自行安裝即可，注意要記下安裝目錄，等下要用。如果下載的是ZIP壓縮包，解壓到任意目錄即可。三、配置eNSP的vlc參數(shù)菜單-工具-選項(xiàng)-工具配置 VLC后面指定你剛才安裝的目錄vlc.exe四、如圖搭建拓?fù)洌ㄒ部勺约憾x，第一次推薦照著來）五、配置網(wǎng)絡(luò)里的各設(shè)備1 路由器的配置（可以貼進(jìn)去）：sysname ar1220multicast routing-enable# 全局開啟組播功能的命令interface Ethernet0/0/0undo shutdownip address pim sm#接組播服務(wù)器的接口下配置pim為稀疏模式interface Ethernet0/0/1undo shutdownip address pim sm#接三層交換機(jī)的接口下配置pim為稀疏模式ospf 1#配置OSPF保證路由器和交換機(jī)之間的單播路由互通area network 55 network 55pim#路由器上配置pim的c-bsr（候選自舉路由器）和c-rp(候選匯聚點(diǎn))c-bsr priority 10c-bsr Ethernet0/0/0#pim稀疏模式配置c-bsr，用來集中通告rp(組播相關(guān)概念的詳細(xì)說明請查HedEx)c-rp priority 10c-rp Ethernet0/0/0#pim稀疏模式配置c-rp,用來選舉rp2 交換機(jī)的配置（可以貼進(jìn)去）sysname sw5700vlan batch 10 20 100# 創(chuàng)建vlanmulticast routing-enable# 全局開啟組播功能的命令interface Vlanif10ip address pim sm#vlanif 10接口下開啟pim稀疏模式igmp enable#接組播客戶端的接口開啟igmp功能，默認(rèn)是V2interface Vlanif20ip address pim sm#vlanif 20接口下開啟pim稀疏模式igmp enable#接組播客戶端的接口開啟igmp功能，默認(rèn)是V2interface Vlanif100ip address 00 pim sm#vlanif 100接口下開啟pim稀疏模式,此接口是接路由器的，可以不開igmp功能interface GigabitEthernet0/0/1port hybrid pvid vlan 100port hybrid untagged vlan 100interface GigabitEthernet0/0/2port hybrid pvid vlan 10port hybrid untagged vlan 10interface GigabitEthernet0/0/3port hybrid pvid vlan 20port hybrid untagged vlan 20ospf 1#配置OSPF保證路由器和交換機(jī)之間的單播路由互通area network 55 network 55 network 553配置MCS服務(wù)器配置好了就點(diǎn)“運(yùn)行”，此時可以看以服務(wù)器的視頻播放。4配置PC1 （PC2類似）配置好了點(diǎn)“加入” “啟動VLC”這個時候應(yīng)該可以看到PC上播放的視頻了，和服務(wù)器是一樣的（會有一點(diǎn)滯后）七、驗(yàn)證參數(shù)ar1220display pim interface#可以看到本路由器上參與pim的接口VPN-Instance: public netInterface State NbrCnt HelloInt DR-Pri DR-AddressEth0/0/0 up 0 30 1 (local)Eth0/0/1 up 1 30 1 00#pim上在以太網(wǎng)上要選DR，（local）表示是自己為DRar1220display pim neighbor# 路由器上看到的鄰居是交換機(jī)00VPN-Instance: public netTotal Number of Neighbors = 1Neighbor Interface Uptime Expires Dr-Priority00 Eth0/0/1 00:19:43 00:01:23 1ar1220dis pim routing-table#查看pim組播路由表的命令，也可以用dis multicast routing-tableVPN-Instance: public netTotal 1 (*, G) entry; 1 (S, G) entry(*, ) RP: (local) Protocol: pim-sm, Flag: WC UpTime: 00:01:23 Upstream interface: Register Upstream neighbor: NULL RPF prime neighbor: NULL Downstream interface(s) information: Total number of downstreams: 1 1: Ethernet0/0/1 Protocol: pim-sm, UpTime: 00:01:23, Expires: 00:03:06(00, ) RP: (local) Protocol: pim-sm, Flag: SPT 2MSDP LOC ACT UpTime: 00:03:39 Upstream interface: Ethernet0/0/0 Upstream neighbor: NULL RPF prime neighbor: NULL Downstream interface(s) information: Total number of downstreams: 1 1: Ethernet0/0/1 Protocol: pim-sm, UpTime: 00:01:23, Expires: 00:03:06sw5700dis pim rp-info#查看rp的信息，交換機(jī)上可以看到rp是路由器VPN-Instance: public netPIM-SM BSR RP Number:1Group/MaskLen: /4 RP: #這里可以看到rp的地址是，優(yōu)先級是10，候選RP的優(yōu)先級越高越容易成為RP。 Priority: 10 Uptime: 00:18:37 Expires: 00:01:36sw5700dis multicast routing-table#交換機(jī)上的組播路由表Multicast routing tableTotal 1 entry00001.(00, ) Uptime: 00:01:53 Upstream Interface: Vlanif100#組播來源的接口是vlan100List of 2 downstream interfaces#組播流去向：vlan10 vlan20 1: Vlanif10 2: Vlanif20sw5700display igmp interface#查看參與IGMP的接口Interface informationVlanif10(): IGMP is enabled# IGMPCurrent IGMP version is 2#IGMP版本是2 IGMP state: up IGMP group policy: none IGMP limit: - Value of query interval for IGMP (negotiated): - Value of query interval for IGMP (configured): 60 s Value of other querier timeout for IGMP: 0 s Value of maximum query response time for IGMP: 10 sQuerier for IGMP: (this router)#查詢路由器是本路由器 Total 1 IGMP Group reportedVlanif20(): IGMP is enabled Current IGMP version is 2 IGMP state: up IGMP group policy: none IGMP limit: - Value of query interval
