华为三层交换机配置实例一例

华为三层交换机配置实例一例服务器1双网卡，内网IP:192.168.0.1，其它计算机通过其代理上网PORT1属于VLAN1PORT2属于VLAN2PORT3属于VLAN3VLAN1的机器可以正常上网配置VLAN2的计算机的网关为：192.168.1.254配置VLAN3的计算机的网关为：192.168.2.254即可实现VLAN间互联如果VLAN2和VLAN3的计算机要通过服务器1上网则需在三层交换机上配置默认路由系统视图下：ip route-static 0.0.0.0 0.0.0.0 192.168.0.1然后再在服务器1上配置回程路由进入命令提示符route add 192.168.1.0 255.255.255.0 192.168.0.254route add 192.168.2.0 255.255.255.0 192.168.0.254这个时候vlan2和vlan3中的计算机就可以通过服务器1访问internet了~~华为路由器与CISCO路由器在配置上的差别＂华为路由器与同档次的CISCO路由器在功能特性与配置界面上完全一致，有些方面还根据国内用户的需求作了很好的改进。

例如中英文可切换的配置与调试界面，使中文用户再也不用面对着一大堆的英文专业单词而无从下手了。

另外它的软件升级，远程配置，备份中心，PPP回拨，路由器热备份等，对用户来说均是极有用的功能特性。

在配置方面，华为路由器以前的软件版本(VRP1.0－相当于CISCO的IOS)与CISCO有细微的差别，但目前的版本(VRP1.1)已和CISCO兼容，下面首先介绍VRP软件的升级方法，然后给出配置上的说明。

一、VRP软件升级操作升级前用户应了解自己路由器的硬件配置以及相应的引导软件bootrom的版本，因为这关系到是否可以升级以及升级的方法，否则升级失败会导致路由器不能运行。

在此我们以从VRP1.0升级到VRP1.1为例说明升级的方法。

三层交换机路由配置实例

三层交换机路由配置一、三层交换机VLAN间路由建立某公司有两个主要部门：技术部和销售部，分处于不同的办公室，为了安全和便于管理对两个部门的主机进行了VLAN划分，技术部和销售部分处于不同VLAN。

现由于业务需要销售部和技术部的主机能够相互访问，获得相应资源，两个部门的交换机通过一台三层交换机进行连接。

在交换机上建立2个Vlan：Vlan10分配给技术部及Vlan20分配给销售部。

为了实现两部门的主机能够相互访问，在三层交换机上开启路由功能，并在Vlan10中设置IP地址为192.168.10.1；在Vlan20中设置IP地址为192.168.20.1，查看三层交换机路由表，会发现在三层交换机路由表内有2条直连路由信息，实现在不同网络之间路由数据包，从而达到2个部门的主机可以相互访问，拓朴图如图所示。

三层交换机与路由器的配置实例（图解）目的：学会使用三层交换与路由器让处于不同网段的网络相互通信实验步骤：一：二层交换机的配置：在三个二层交换机上分别划出两VLAN，并将二层交换机上与三层交换或路由器上的接线设置为trunk接口二：三层交换机的配置：1：首先在三层交换上划出两个VLAN，并进入VLAN为其配置IP，此IP将作为与他相连PC 的网关。

2：将与二层交换机相连的线同样设置为trunk接线，并将三层交换与路由器连接的线设置为路由接口（no switchsport）3：将路由器和下面的交换机进行单臂路由的配置实验最终结果：拓扑图下各个PC均能相互通信交换机的配置命令：SW 0:Switch>Switch>enSwitch#confConfiguring from terminal, memory, or network [terminal]?Enter configuration commands, one per line.

三层交换机配置实例

三层交换机配置实例注意，为防止VTP出错，建议多保存，VTP在最后配置这个拓扑图主要实现以下功能：配置VTP域,减轻管理员工作量,配置PVST,避免环路的产生，做好DHCP 中继，使不同vlan中PC能够动态获取IP地址，设置以太网通道，增加数据流量，三层交换机配置路由功能,使不同vlan 之间的通信，大体配置和思路如下：1，IP规划：3550-1 vlan1 :192.168.1.1

将PC4；PC5添加进去好了，规划完了，下面我们开始命令行配置吧：3550-1的配置如下：配置交换机的三层路由功能3550-1#config terminal3550-1<config>#ip routing // 启用三层路由功能配置VTP域：3550-1>enable3550-1#config terminal3550-1<config>#vtp domain benet //
