去年学完了Cisco的路由交换，从CCNA学到CCIE。学完之后才发现，整个国内市场好像更倾向于使用华为、H3C这类国有网络设备厂商。不过还好，至少网络的基础理论知识是相同的，于是买了基本关于HUAWEI认证的书籍，准备稍稍过一遍，有了思科的学习经历，对应华为而言应该不难，那么开始吧！
华为认证体系
华为和思科一样拥有一整套的认证体系。
操作系统
有过思科学习经历的都知道思科的实验大部分都是在GNS3中进行的，虽然思科官方有packet tracer，但是能通过packet tracer做出来的实验非常少，只能模拟CCNA阶段的实验，我是特别喜欢GNS3，因为他具备跨平台性，基本思科的实验都是在Linux上完成，搭配IOU，无需通过虚拟机获取镜像非常省资源。 那么华为也有自己的模拟器，叫做ENSP，目前最新的版本是1.2.00.360。华为的操作系统叫VRRP（Versatile Routing Platform），它是整个华为数通产品的通用网络操作系统。
1.获取模拟器的方式：
http://support.huawei.com/enterprise/toolsinfo?lang=zh&idAbsPath=0602_ROOT&pid=0602_ROOT&show=showVDetail&toolId=TL1000000015
2.启动路由器
启动路由器和通过gns3拖拽路由器或者交换机设备启动是一样的方式，如图拖拽设备后通过线缆连接 然后选择菜单栏的启动按钮即可启动设备
3.启动界面
启动完成后，就进入了配置路由器的界面了，和思科一样，华为的管理型网络设备的配置都是在命令行模式下进行。
VRRP各模式下的切换
启动设备后我们可以通过命令在各个模式下切换和配置，与思科基本思路是一样的，但仍有些差异，下面简单看下与思科对比最基本的配置命令
1.调出当前模式下所能使用的命令，在命令行中按？号键即可看到。

sys
system-view
Enter system view, return user view with Ctrl+Z.

（1）我们首先需要知道连接的接口是什么？单击菜单栏的显示所有接口显示出来。
（2）然后，我们开始配置，第一步，进入接口，不记得的单词可以按？号显示哦！

IP on the interface GigabitEthernet0/0/0 has entered the UP state.
[Huawei-GigabitEthernet0/0/0]（4）退出接口模式
Huawei-GigabitEthernet0/0/0]quit4.修改设备名称，使用sysname去命名，比如我们现在的交换机在杭州市福地机房A1楼层B9机房C09机柜第48U上，我们可以这样缩写。方便我们定位设备位置，以便于设备出现故障我们能够快速知道故障设备去进行排查。

clock timezone BJ add 08:00:00
clock datetime 7:41:50 2015-10-17 7.设置标题信息
如果需要在登录路由器提供警告信息，我们可以设置header login为登录标题，header shell 可以设置登录成功后标题文本信息为"Warning, do not touch this device"。 HZ-FD-A1-B9-C09-48]header login information "hello" [HZ-FD-A1-B9-C09-48]header shell information "Warning, do not touch this device" [ [HZ-FD-A1-B9-C09-48]quit quit

以上是关于华为路由器的简单配置。当然，华为和H3C的配置几乎一模一样，学完华为H3C信手拈来。
