校园组网实习

实验拓扑图

实验要求

要求
1、出口路由使用 NAT。
2、校园内服务器搭建www、FTP、DNS。
3、宿舍汇聚交换机与核心交换机链路使用链路聚合。
4、校园内除服务器不使用自动分配地址，其他pc使用自动获取ip地址。
5、核心交换机建VLAN、DHCP。
6、使用acl在服务器交换机设置FTP只允许教一楼的ip访问。
7、交换机管理vlan10，设置telnet 用户名个人名字拼音，密码为学号?

方法二：采用链路聚合方式（LACP）

链路聚合（Link?Aggregation），是指将多个物理端口捆绑在一起，成为一个逻辑端口，以实现出入流量在各成员端口中的负荷分担，交换机根据用户配置的端口负荷分担策略决定报文从哪一个成员端口发送到对端的交换机

[sw4-Vlanif10]ip add 10.1.1.253 24

DHCP配置完成后，内部网络已经可以相互ping通

接下来配置外网

首先配置一条缺省指向外网

sw4

[sw4]ip route-static 0.0.0.0 0 10.1.1.254

R1

[r1]int g 0/0/0

[r1-GigabitEthernet0/0/0]ip add 10.1.1.254 24

[r1-GigabitEthernet0/0/0]int g 0/0/1

[r1-GigabitEthernet0/0/1]ip add 221.5.150.1 24

R1静态指向内部链路聚合汇总后的网络地址

[r1]ip route-static 172.16.0.0 16 10.1.1.253

R1配置OSPF，10.1.1.0/24宣告在Area 1内，221.5.150.0/24宣告在Area 0内，通过OSPF建邻来互相获取对方的路由信息

[r1]ospf 1 router-id 1.1.1.1

[r1-ospf-1]area 0

[r1-ospf-1-area-0.0.0.0]network 221.5.150.0 0.0.0.255

[r1-ospf-1-area-0.0.0.0]q

[r1-ospf-1]area 1

[r1-ospf-1-area-0.0.0.1]network 10.1.1.0 0.0.0.255

R2

[r2]int g 0/0/0

[r2-GigabitEthernet0/0/0]ip add 221.5.150.2 24

[r2-GigabitEthernet0/0/0]int g 0/0/1

[r2-GigabitEthernet0/0/1]ip add 121.31.43.254 24

[r2]ospf 1 router-id 2.2.2.2

[r2-ospf-1]area 0

[r2-ospf-1-area-0.0.0.0]network 121.31.43.0 0.0.0.255

[r2-ospf-1-area-0.0.0.0]network 221.5.150.0 0.0.0.255

R1上做NAT，因为R1是校园内网的出口路由器，需要R1指向外网，而因为ip地址有限，所以需要采用NAT技术来实现外网的ip映射到内网，从而可以将一个ip地址多用。

采用的是动态NAT配置

[r1]acl 2000 ------------先采用ACL方式来选取我们需要抓取的流量
[r1-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r1-acl-basic-2000]int g 0/0/1
[r1-GigabitEthernet0/0/1]nat outbound 2000 ------------然后在出接口上调用NAT中我们写的ACL

此时内部PC可以ping通R2

接下来配置校园内网服务器的交换机

sw5?
[sw5]vlan batch 2 10
[sw5]int g 0/0/3
[sw5-GigabitEthernet0/0/3]port link-type access?
[sw5-GigabitEthernet0/0/3]port default vlan 2
[sw5-GigabitEthernet0/0/3]int g 0/0/4
[sw5-GigabitEthernet0/0/4]port link-type access?
[sw5-GigabitEthernet0/0/4]port default vlan 2
[sw5-GigabitEthernet0/0/4]int g 0/0/5
[sw5-GigabitEthernet0/0/5]port link-type access?
[sw5-GigabitEthernet0/0/5]port default vlan 2
[sw5-GigabitEthernet0/0/5]q

sw5上采用链路聚合的方式来配置接口类型

[sw5]int Eth-Trunk 5
[sw5-Eth-Trunk5]trunkport g 0/0/1 0/0/2
[sw5-Eth-Trunk5]port link-type trunk?
[sw5-Eth-Trunk5]port trunk allow-pass vlan 2 10

同样sw4上也要做对应的配置
[sw4]int Eth-Trunk 5
[sw4-Eth-Trunk5]trunkport g 0/0/1 0/0/2
[sw4-Eth-Trunk5]port link-type trunk?
[sw4-Eth-Trunk5]port trunk allow-pass vlan 2 10
[sw4-Eth-Trunk5]q
[sw4]vlan 2
[sw4-vlan2]q
[sw4]int vlanif 2
[sw4-Vlanif2]ip add 172.16.1.126 25

sw5上配置高级ACL允许ftp流量通过

因为要求只允许一教楼的IP访问ftp，所以采用高级ACL方式限制

[sw5]acl 3000

[sw5-acl-adv-3000]

rule 5 permit tcp source 172.16.2.0 0.0.0.255 destination 172.16.1.5 0.0.0.127 destination eq 21

[sw5-acl-adv-3000]

rule 10 permit tcp source 172.16.3.0 0.0.0.255 destination 172.16.1.5 0 destination eq 21

[sw5-acl-adv-3000]

rule 15 permit tcp source 172.16.4.0 0.0.0.255 destination 172.16.1.5 0 destination eq 21

[sw5-acl-adv-3000]

rule deny tcp source any destination 172.16.1.5 0 destination-port eq 21

[sw5-acl-adv-3000]

rule 20 deny tcp source 172.16.100.0 0.0.0.127 destination 172.16.1.5 0?destination-port eq 21

[sw5-acl-adv-3000]

rule 20 deny tcp source 172.16.101.0 0.0.0.127 destination 172.16.1.5 0 destination-port eq 21

[sw5-acl-adv-3000]q

[sw5]int Eth-Trunk 5 ----------------在sw5的聚合接口上调用ACL

[sw5-Eth-Trunk5]traffic-filter inbound acl 3000 -------在sw5的聚合接口的入接口方向绑定ACL3000

[sw4]aaa
[sw4-aaa]local-user shenyiming privilege level 3 password cipher 21060311
[sw4-aaa]local-user shenyiming service-type telnet
[sw4-aaa]q

[sw4]user-interface vty 0 4
[sw4-ui-vty0-4]authentication-mode aaa

R1上telnet远程登录sw4

在R1上远程登录的sw4上登录ftp
