VRP概述

VRP概述一、VRP简介 VRP-*二、VRP体系结构 VRP-*三、VRP主要特性 VRP-*3.1 终端服务 VRP-* 3.2 链路层协议 VRP-*3.3 IP应用 VRP-* 3.4 路由协议 VRP-*3.5 备份应用 VRP-* 3.6 拨号功能 VRP-*3.7 安全特性 VRP-* 3.8 VPN服务 VRP-*3.9 QoS保障 VRP-* 3.10 IP语音功能 VRP-*3.11 SNA特性 VRP-* 3.12 MPLS特性 VRP-*3.13 组播路由 VRP-* 3.14 SNMP网管 VRP-*VRP概述一、 VRP简介VRP（Versatile Routing Platform，通用路由平台）是华为公司数据通信产品的通用网络操作系统平台，为Quidway® 系列路由器、Radium骨干ATM交换机、Quidway® S系列以太网交换机及Quidway® A8010接入服务器等设备提供统一的操作平台。

VRP是华为公司具有完全自主知识产权的网络操作系统，可以运行在多种硬件平台之上并拥有一致的网络界面、用户界面和管理界面，为用户提供了灵活丰富的应用解决方案。

同时VRP是一个持续发展的平台，可以最大程度地保护用户投资。

VRP平台以IP业务为核心，实现组件化的体系结构，拥有多达300项以上的特性。

在提供丰富功能特性的同时，还提供基于应用的可裁剪能力和可伸缩能力。

二、 VRP体系结构VRP平台以TCP/IP协议栈为核心，实现了数据链路层、网络层和应用层的多种协议，在操作系统中集成了路由技术、QoS 技术、VPN技术、安全技术和IP语音技术等数据通信要件，并以IP转发引擎（TurboEngine）技术作为基础，为网络设备提供了出色的数据转发能力。

其体系结构图如下：图VRP-1 VRP体系结构示意图▪IP转发引擎：包括传统IP报文转发、IP快速转发、QoS服务质量、策略路由、安全能力及防火墙等。

同时对登录用户也划分为4个级别，分别与命令级别相对应，即不同级别的用户登录后，只能使用等于或低于自己级别的命令。为了防止未授权用户的非法侵入，用户在使用super [ level ]命令从低级别切换到高级别时，要进行用户身份验证，即需要输 super 入切换口令（如果用户已经使用命令super password [ level level ] { simple | cipher } password设置了切换口令）。为了保密，用户在屏幕上看不到所键入的口令，如果三次以内输入正确的口令，则切换到高级别用户，否则保持原用户级别不变。

链路聚合应用场景

链路聚合应用场景
链路聚合是指将多个网络链路合并成一个逻辑链路，从而提高网络带宽和稳定性。

链路聚合在现代网络中被广泛应用，以下是一些常见的链路聚合应用场景：
1. 企业宽带接入：企业通常需要大带宽的网络连接，以支持各
种应用程序和业务需求。

链路聚合可以将多个宽带连接合并为一个逻辑连接，提高企业网络的带宽和稳定性。

2. 数据中心网络：数据中心通常需要高可用性和高带宽的网络
连接，以支持各种云计算和大数据应用。

链路聚合可以将多个物理链路聚合成一个逻辑链路，从而提高数据中心网络的带宽和可靠性。

3. 网络负载均衡：链路聚合可以用于实现网络负载均衡，将网
络流量分布到多个链路上，从而提高网络的性能和可靠性。

4. VPN接入：链路聚合可以用于实现VPN连接，提高VPN的可
靠性和带宽。

5. 移动接入：移动网络通常需要高带宽和低延迟的网络连接，
以支持各种移动应用。

链路聚合可以将多个无线网络连接合并为一个逻辑连接，从而提高移动网络的带宽和稳定性。

总之，链路聚合可以在各种网络场景中提高网络的带宽和稳定性，从而满足各种应用程序和业务需求。

H3C配置经典全面教程(

H3C配置经典全面教程〔经验和资料收集整理版〕1 H3C MSR路由器、交换机根本调试步骤〔初学级别〕：1.1 如何登陆进路由器或交换机搭建配置环境第一次使用 H3C系列路由器时，只能经过配置口 (Console) 进行配置。

1〕将配置电缆的RJ-45 一端连到路由器的配置口(Console) 上。

2〕将配置电缆的DB-9(或 DB-25)孔式插头接到要对路由器进行配置的微机或终端的串口上。

备注：登陆交换机的方法与路由器的一致，现仅用路由器举设置微机或终端的参数〔进入路由器或交换机〕1〕翻开微机〔笔录本电脑〕或终端。

若是使用微机进行配置，需要在微机上运行终端仿真程序，如Windows的超级终端。

2〕第二步：设置终端参数a、命名此终端H3C 也许自己想命的名b、选择串口一般采纳COM口，常采纳COM1c、设置终端量细参数 ( 此处点击“默认值〞即可)d、翻开路由器的电源，路由器进行启动e、当路由器启动达成后，回车几下，当出现 <H3C>时即可配置路由器。

四种VLAN实现方法

VLAN技术白皮书--------------------------------------------------------------------------------关键词VLAN，VLAN聚合，PVLAN，GVRP，VTP1 VLAN概述VLAN（Virtual Local Area Network）即虚拟局域网，是一种通过将局域网内的设备逻辑地而不是物理地划分成一个个网段从而实现虚拟工作组的新兴技术。

IEEE于1999年颁布了用以标准化VLAN实现方案的802.1Q协议标准草案。

VLAN技术允许网络管理者将一个物理的LAN逻辑地划分成不同的广播域（或称虚拟LAN，即VLAN），每一个VLAN都包含一组有着相同需求的计算机工作站，与物理上形成的LAN 有着相同的属性。

但由于它是逻辑地而不是物理地划分，所以同一个VLAN内的各个工作站无须被放置在同一个物理空间里，即这些工作站不一定属于同一个物理LAN网段。

一个VLAN内部的广播和单播流量都不会转发到其他VLAN中，从而有助于控制流量、减少设备投资、简化网络管理、提高网络的安全性。

VLAN是为解决以太网的广播问题和安全性而提出的一种协议，它在以太网帧的基础上增加了VLAN头，用VLAN ID把用户划分为更小的工作组，限制不同工作组间的用户二层互访，每个工作组就是一个虚拟局域网。

虚拟局域网的好处是可以限制广播范围，并能够形成虚拟工作组，动态管理网络。

VLAN在交换机上的实现方法，可以大致划分为4类:1、基于端口划分的VLAN这种划分VLAN的方法是根据以太网交换机的端口来划分，比如Quidway S3526的1~4端口为VLAN 10，5~17为VLAN 20，18~24为VLAN 30，当然，这些属于同一VLAN的端口可以不连续，如何配置，由管理员决定，如果有多个交换机，例如，可以指定交换机1 的1~6端口和交换机2 的1~4端口为同一VLAN，即同一VLAN可以跨越数个以太网交换机，根据端口划分是目前定义VLAN的最广泛的方法，IEEE 802.1Q规定了依据以太网交换机的端口来划分VLAN的国际标准。

华为网络工程师培训：详解交换机VLAN和链路聚合(LACP)组网

华为网络工程师培训：vlanif接口实现跨越三层网络通信配置组网需求：一个公司有综合科N台电脑，财务科N台电脑，分别在两个交换机上。

分别属于不同的vlan。

现在需要不同科室之间互访，则需要跨设备VLAN互访，使用vlanif接口实现跨越三层网络通信，如何实现。

拓扑结构如图：一、本节知识点：2、Access类型端口执行命令port default vlan vlan-id，将端口加入到指定的VLAN中。

Access类型端口只能属于1个VLAN，一般用于连接计算机端口；3、Trunk类型端口Trunk类型端口可以允许多个VLAN通过,可以接收和发送多个VLAN 报文Ip地址设置：3、vlanif接口：是三层逻辑接口，在二层设备上创建VLANIF接口后，可部署三层特性可以实现VLAN之间的通信。

4、静态路由：静态路由（英语：Static routing），一种路由的方式，路由项（routing entry）由手动配置，由网络管理员逐项加入路由表。

文章下面有实际操作录像视频，讲的比较详细，不懂的请关注我私信我。

三、IP设置：四、华为交换机1的配置：#sysname Huawei#vlan batch 10 30 //创建vlan 10和30#interface Vlanif10 //创建vlanif10三层接口ip address 192.168.10.254 255.255.255.0 //设置IP地址#interface Vlanif30 //创建vlanif30三层接口ip address 192.168.30.1 255.255.255.0 //设置IP地址#interface MEth0/0/1#interface Ethernet0/0/1port link-type access //接口类型为accessport default vlan 10 //该接口加入到vlan 10#interface Ethernet0/0/2port link-type trunk //接口类型为trunkport trunk allow-pass vlan 2 to 4094 //允许所有vlan通过#ip route-static 192.168.20.0 255.255.255.0 192.168.30.2//设置到192.168.20.0网络的静态路由#user-interface con 0user-interface vty 0 4#return交换机2的配置和交换机1的配置是一样的，不再赘述。

vrp协议原理

vrp协议原理宝子！今天咱们来唠唠VRP协议的原理呀。

VRP呢，就像是网络世界里的一个超级管家。

你想啊，在一个复杂的网络环境里，有各种各样的设备，就像一群调皮的小怪兽。

VRP就是那个能把它们管得服服帖帖的大英雄。

从最基础的说起哈，VRP是运行在华为设备上的一种操作系统。

它的存在呢，就是为了让不同的网络设备能够相互交流、协同工作。

这就好比是一群来自不同地方、讲不同方言的小伙伴，VRP就是那个能让大家都听懂彼此的翻译官。

你看啊，网络设备有路由器、交换机啥的。

每个设备都有自己的功能和任务。

路由器就像是网络里的快递小哥，负责把数据从一个地方送到另一个地方。

交换机呢，就像是一个交通指挥员，指挥着数据在本地网络里的流动。

VRP协议就得让这些不同角色的设备知道自己该干啥，啥时候干。

VRP协议有个很重要的部分就是命令行界面（CLI）。

这个界面就像是VRP的嘴巴，你可以通过输入各种命令来告诉VRP你想要设备做什么。

比如说，你想给某个接口配置个IP地址，就可以在CLI里敲上相应的命令。

这就像你跟管家说：“管家呀，把那个房间的门牌号改成这个数字。

”然后VRP就会按照你的要求去配置设备。

再说说VRP的路由功能。

路由就像是网络里的导航系统。

VRP协议要根据网络的拓扑结构，也就是网络里各个设备的连接关系，来确定数据该怎么传输。

比如说，从A点到B点有好几条路可以走，VRP就要选择一条最优的路。

这就好比你要从家去商场，有好几条公交线路，VRP会帮你选择那条不堵车、最快到达的线路。

VRP协议还特别注重安全性哦。

在网络这个大江湖里，有很多潜在的危险，就像有小贼想偷数据一样。

VRP可以设置各种安全策略，比如访问控制列表（ACL）。

这就像是给你的网络房子装上了防盗门和防盗窗，只有被允许的人或者数据才能进出。

而且呀，VRP协议还支持多种网络协议的交互。

就像一个人会多种语言一样，可以和不同的网络设备用它们能听懂的“语言”交流。

比如它能和运行着其他协议的设备一起构建一个大型的网络环境。
