### 1、项目背景
>XX公司总部位于北京，在上海和深圳分别设有研究所与办事处，通过组建网络将三地连接起来：北京总部有员工100人，一级部门四个（划分Vlan，IP地址规划），服务器2台，服务器与交换机做链路聚合，总部路由协议使用ospf；深圳办事处有员工30人，上海研究所有员工40人，办事处与研究所不分部门,采用DHCP分配IP地址；总部与分支机构之间使用SDH线路连接，其中总部与深圳之间使用2M线路（ppp+chap），总部与上海之间使用2条2M线路（帧中继+路由备份）。

### 2、网络建设目标
> 网络带宽升级，达到千兆骨干，百兆到桌面
增强网络的可靠性及可用性
网络要易于管理、升级和扩展
确保内网安全及同办事处之间交互数据的安全

### 3、拓扑规划
<img src="https://www.qfwys.cn/boke/imgforA/03.png" style="width:100%">

### 4、LAN规划（各部门局域网规划）
> 总部按部门划分VLAN
人事行政及财务/商务划为一个VLAN：VLAN 10
产品研发部划为一个VLAN：VLAN 20
技术支持部划为一个VLAN：VLAN 30
服务器区划为一个VLAN：VLAN 40
分支机构不划分VLAN
每个分支机构单独使用一个C类地址
254作为网关
总部及分支机构全部使用DHCP分配IP地址

### 5、网络设备选型和命名
① 北京总部：
> 核心交换机         选型：S5700-28C-HI      命名：BJ-S5700-LSW1
服务器区交换机     选型：S3700-26C-HI      命名：BJ-S3700-LSW2
接入交换机         选型：S3700-26C-HI      命名：BJ-S3700-LSW3、LSW4、LSW5
互连及出口路由器   选型：AR2240            命名：BJ-AR2240-AR1

② 深圳办事处：
> 互连路由器         选型：AR1220            命名：SZ-AR1220-AR2
接入交换机         选型：S3700-26C-HI      命名：SZ-S3700-LSW6

③ 上海研究所：
> 互连路由器         选型：AR1220            命名：SH-AR1220-AR3
接入交换机         选型：S3700-26C-HI      命名：SH-S3700-LSW7

### 6、路由规划
<img src="https://www.qfwys.cn/boke/imgforA/06.png" style="width:100%">

### 7、配置
首先给交换机和路由器配置命名（这里以LSW1为例）：
<img src="https://www.qfwys.cn/boke/imgforA/07.png" style="width:100%">

具体配置：
分别将LSW1和LSW2的g0/0/1和g0/0/2配置为一个链路聚合口：
\========================================================
[BJ-S5700-LSW1]interface Eth-Trunk 12
[BJ-S5700-LSW1-Eth-Trunk12]trunkport g0/0/1
[BJ-S5700-LSW1-Eth-Trunk12]trunkport g0/0/2
\========================================================
[BJ-S3700-LSW2]interface Eth-Trunk 12
[BJ-S3700-LSW2-Eth-Trunk12]trunkport g0/0/1
[BJ-S3700-LSW2-Eth-Trunk12]trunkport g0/0/2
\========================================================

在三层交换机LSW1上划分vlan，并给相应的vlanif虚拟口配置ip地址：
