CISCO路由器PPPoE实验报告

CISCO路由器PPPoE实验报告
题⽬：PPPOE实验
实验拓扑如下：
实验要求：
1.在pppoe-client2路由器上使⽤NAT协议，让内部主机能够上⽹
2.路由器pppoe-client2和pppoe-client1通过pppoe协议拨号连接pppoe-server服务器，
3.在pppoe-server和ISP-router之间使⽤ospf路由选择协议
实验⽬的：
掌握1.pppoe在路由器上的配置过程
2.NAT
3.单区域ospf
实验步骤:
1.使⽤⼩凡模拟器搭建实验环境。

2.
2.在pppoe-server 路由器上配置如下
PPPoe-server(config-if)#username cisco password cisco 创建⼀个拨号帐号。

PPPoe-server(config)#vpdn enable //启⽤vpdn虚拟私有拨号⽹络协议
PPPoe-server(config)#vpdn-group adsl0 //创建⼀个虚拟私有拨号⽹络组，起名为adsl0 PPPoe-server(config-vpdn)#accept-dialin //允许拨⼊改组
PPPoe-server(config-vpdn-acc-in)#protocol pppoe //并启⽤pppoe协议
%Only one PPPoE VPDN group can be configured
PPPoe-server(config-vpdn-acc-in)#virtual-template 1 //关联⼀个虚拟接⼝
PPPoe-server(config-vpdn-acc-in)#exit
PPPoe-server(config-vpdn)#pppoe limit per-mac 10 //限制拨号连接的mac数⽬为10
PPPoe-server(config)#int f0/0 启⽤物理接⼝
PPPoe-server(config-if)#ip add 1.1.1.1 255.255.255.0 配置ip地址
PPPoe-server(config-if)#no shut
PPPoe-server(config-if)#pppoe enable 并在该物理接⼝下启⽤pppoe协议
PPPoe-server(config-if)#int virtual-template1 配置虚拟接⼝
PPPoe-server(config-if)#ip address 200.0.0.1 255.255.255.0
PPPoe-server(config-if)#peer default ip address pool ad 指定拨⼊端的iP池，名字为ad PPPoe-server(config-if)#ppp
authentication chap pap callin 启⽤混合认证⽅式
PPPoe-server(config-if)#ppp ipcp dns 202.102.128.68 202.102.134.68 给拨⼊端指派dns PPPoe-server(config-if)#ip local pool vt1 200.0.0.20 200.0.0.254 指定拨⼊端能够使⽤的ip范围
PPPoe-server(config)#
PPPoe-server(config)#router ospf 10 启⽤ospf路由选择协议
PPPoe-server(config-router)#net 200.0.0.0 0.0.0.255 area 0 通告直连⽹络号
PPPoe-server(config-router)#net 100.0.0.0 0.0.0.255 area 0
PPPoe-server(config-router)#
pppoe-server(config)#do sho ip rou ospf 查看ospf路由表
5.0.0.0/32 is subnetted, 1 subnets
O 5.5.5.5 [110/11] via 100.0.0.2, 00:03:07, FastEthernet1/0
pppoe-server(config)#
pppoe-server(config)#do ping 5.5.5.5 测试
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 5.5.5.5, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/211/364 ms

pppoe-server(config)#
在pppoe-client2上配置如下
pppoe-client2(config)#vpdn enable 同上，在路由器作为拨⼊端时也要启⽤vpdn协议pppoe-client2(config)#int f0/0 pppoe-client2(config-if)#no shut 启⽤连接拨号的物理接⼝
