H3C配置案例大全(内部分享)
光纤链路排错经验一、组网：用户采用4台S5500作为接入交换机、1台S5500作为核心交换机组网，4台接入交换机分别在三个仓库以及门卫处与核心机房都是通过2根八芯单模光纤走地井连接，在这5个机房再通过跳纤来连接到交换上。
用户要求实现内网的用户主机访问公共服务器资源，并实现全网互通。
组网如下图所示：二、问题描述：PC现无法访问server服务器，进一步发现S5500光纤端口灯不亮，端口信息显示down状态。
在核心交换机端通过自环测试发现该端口以及光模块正常，接入交换机端也同样测试发现正常。
监控网络正常使用，再将网络接口转接到监控主干链路上，发现网络同样无法正常使用。
三、过程分析：想要恢复链路，首先要排查出故障点，根据故障点情况结合实际恢复链路通畅。
在这里主要分析光纤通路，光信号从接入交换机光口出来通过跳线，转接到主干光纤，然后再通过核心跳线转接到核心交换上。
由于该链路不通，首先要排除两端接口以及光模块问题，这里使用自环检测(如果是超远距离传输光纤线缆需要接光衰然后在自环，防止烧坏光模块)。
当检测完成发现无问题，再测试接入端的光纤跳纤：如果是多模光纤可以将一端接到多模光纤模块的tx口，检测对端是否有光；单模光纤如果没有光功率计可以使用光电笔检测(该方法只能检测出中间无断路，并不能检测出线路光衰较大的情况)。
最后再检测主线路部分，检测方式同跳线一样。
光路走向流程如图所示：四、解决方法：从上述的分析可以看出，只要保证了光信号一出一收两条路径都能正常就可以解决用户无法访问服务器的问题。
为了保证光路正常通路，最好的解决方法就是，通过使用光功率计来检测对端发射光在本端的光功率是否在光口可接受范围内。
由于用户组网使用了一些监控设备来接入该主干光缆，并且该光路现正常使用，通过将网络光纤转接到该监控主干光缆，发现网络光路仍然不通；并且两端端口自环检测正常。
由此可以判断出主要问题在两端的跳纤上。
如图所示：在没有光功率计并且客户业务又比较着急恢复的情况，可以先将两端的接入跳纤更换。

组播配置举例组播配置举例关键词：IGMP、IGMP Snooping、组播VLAN、PIM、MSDP、MBGP摘要：本文主要介绍组播功能在具体组网中的应用配置，包括以下两种典型组网应用：域内的二、三层组播应用情况，以及域间的三层组播应用情况。
缩略语：—目录1 特性简介2 应用场合3 域内二、三层组播配置举例3.1 组网需求3.2 配置思路3.3 配置步骤3.3.1 Router A的配置3.3.2 Router B的配置3.3.3 Router C的配置3.3.4 Router D的配置3.3.5 Switch A的配置3.3.6 Switch B的配置3.3.7 Switch C的配置3.4 验证结果4 域间三层组播配置举例4.1 组网需求4.2 配置思路4.3 配置步骤4.3.1 Router A的配置4.3.2 Router B的配置4.3.3 Router C的配置4.3.4 Router D的配置4.3.5 Router E的配置—4.3.6 Router F的配置4.4 验证结果5 相关资料5.1 相关协议和标准1 特性简介组播是指在IP网络中将数据包以尽力传送的形式发送到某个确定的节点集合，其基本思想是：源主机只发送一份数据，其目的地址为组播组地址；组播组中的所有接收者都可收到同样的数据拷贝，并且只有组播组内的主机可以接收该数据，而其它主机则不能收到。
作为一种与单播和广播并列的通信方式，组播技术能够有效地解决单点发送、多点接收的问题，从而实现了IP网络中点到多点的高效数据传送，能够节约大量网络带宽、降低网络负载。
以下是对各常用组播协议的简单介绍：1. IGMPIGMP是TCP/IP协议族中负责IP组播组成员管理的协议，用来在IP主机和与其直接相邻的组播路由器之间建立、维护组播组成员关系。
IGMP运行于主机和与主机直连的路由器之间，其实现的功能是双向的：一方面，主机通过IGMP通知路由器希望接收某个特定组播组的信息；另一方面，路由器通过IGMP周期性地查询局域网内的组播组成员是否处于活动状态，实现所连网段组成员关系的收集与维护。
2. IGMP SnoopingIGMP Snooping是运行在二层设备上的组播约束机制，用于管理和控制组播组。
运行IGMP Snooping的二层设备通过对收到的IGMP报文进行分析，为二层端口和组播MAC地址建立起映射关系，并根据这个映射关系转发组播数据。
3. 组播VLAN在传统的组播点播方式下，当连接在二层设备上、属于不同VLAN的用户分别进行组播点播时，三层组播设备需要向该二层设备的每个VLAN分别发送一份组播数据；而当二层设备运行了组播VLAN之后，三层组播设备只需向该二层设备的组播VLAN发送一份组播数据即可，从而既避免了带宽的浪费，也减轻了三层组播设备的负担。
4. PIMPIM是Protocol Independent Multicast（协议无关组播）的简称，表示可以利用静态路由或者任意单播路由协议（包括RIP、OSPF、IS-IS、BGP等）所生成的单播路由表为IP组播提供路由。
组播路由与所采用的单播路由协议无关，只要能够通过单播路由协议产生相应的组播路由表项即可。
PIM借助单播路由表对组播报文进行RPF检查，以实现对组播数据的转发。
根据转发机制的不同，PIM分为以下两种模式：●PIM-DM：属于密集模式的组播路由协议，使用“推（Push）模式”传送组播数据，通常适用于组播组成员相对比较密集的小型网络；●PIM-SM：属于稀疏模式的组播路由协议，使用“拉（Pull）模式”传送组播数据，通常适用于组播组成员分布相对分散、范围较广的大中型网络。
5. MSDP在基本的PIM-SM模式下，组播源只向本PIM-SM域内的RP注册，且各域的组播源信息是相互隔离的，因此RP仅知道本域内的组播源信息，只能在本域内建立组播分发树。
如果能够有一种机制，使不同域内的RP共享其组播源信息，就可以实现组播数据的跨域传输。
MSDP就是为了解决多个PIM-SM域之间的互连而开发的一种域间组播解决方案，用来发现其它PIM-SM域内的组播源信息。
它通过在各域的RP之间建立MSDP对等体关系，使这些RP可以共享各域内的组播源信息。
尽管MSDP是为域间组播开发的，但它在PIM-SM域内还有着一项特殊的应用——Anycast RP（任播RP）。
Anycast RP是指在同一PIM-SM域内通过设置两个或多个具有相同地址的RP，并在这些RP之间建立MSDP对等体关系，以实现域内各RP之间的负载分担和冗余备份。
6. MBGP当组播源与接收者分布在不同的AS中时，需要跨AS建立组播转发树。
应用MP-BGP协议就可以专门跨AS传输组播路由信息。
BGP-4协议仅应用于单播，MP-BGP是对BGP的多协议扩展，它在现有BGP-4的基础上增强了功能，使BGP 能够为包括组播路由协议在内的多种路由协议提供路由信息：●MP-BGP可以同时为单播和组播维护路由信息，将它们储存在不同的路由表中，保持单播和组播之间路由信息相互隔离；●作为BGP的多协议扩展，MP-BGP可以同时支持单播和组播模式，为两种模式构建不同的网络拓扑结构；●原BGP-4所支持的单播路由策略和配置方法大部分都可应用于组播模式，从而可以根据路由策略为单播和组播维护不同的路由。
MP-BGP在组播上的应用简称为MBGP（组播BGP）。
2 应用场合利用组播技术可以方便地提供一些新的增值业务，包括在线直播、网络电视、网络电台、远程教育、远程医疗、视频会议等对带宽和数据交互的实时性要求较高的信息服务。
如图1 所示，是各常用组播协议在网络中的应用场合示意图。
图1 常用组播协议应用场合示意图3 域内二、三层组播配置举例3.1 组网需求(1)需求分析●某企业的核心网内部通过OSPF协议互连，并拥有两个视频源：Source 1通过组播组G1（225.1.1.1）传送节目1，Source 2则通过组播组G2（225.2.2.2）传送节目2。
要求在核心网通过使用PIM-SM协议实现视频流的组播分发，并利用Anycast RP功能实现双RP负载分担和冗余备份，提高网络可靠性。
●该企业的接入网按部门划分为多个VLAN以方便管理，各部门内的点播者（Receiver）有不同的点播需求：Host A和Host C点播节目1，Host E点播节目2。
要求在接入网通过IGMP、IGMP Snooping和组播VLAN的结合使用，使视频流按需送达各点播者，提高带宽利用率。

(2)配置接入网：●在Router C和Router D的主机侧接口上使能IGMP协议；●在所有交换机上划分VLAN，并在VLAN内使能IGMP Snooping，同时使能丢弃未知组播数据报文功能，以防止交换机在没有二层组播转发表项时将组播数据在VLAN内广播；●在Switch A上配置基于子VLAN的组播VLAN，以避免Router C将不同VLAN 内点播的相同组播数据重复发至Switch A。
