思科pppoe实验

R1模拟为客户端    R2为server端

PPPoE-server(config)#vpdn enable启用虚拟专用网 

PPPoE-server(config)#int e0/0

PPPoE-server(config-if)#no shutdown

PPPoE-server(config-if)#ex

PPPoE-server(config)#username admin password cisco做一个本地认证的 用户名  密码

PPPoE-server(config)#service dhcp                                 开启DHCP

PPPoE-server(config)#ip dhcp pool client                                  给client发送

PPPoE-server(dhcp-config)#network 100.1.1.1 255.255.255.0发送的地址 

PPPoE-server(dhcp-config)#default-router 100.1.1.254    

PPPoE-server(dhcp-config)#dns-server 8.8.8.8

PPPoE-server(dhcp-config)#domain-name cisoc.com

PPPoE-server(dhcp-config)#ex

PPPoE-server(config)#interface virtual-template 1               设置给对方拨号的模板

PPPoE-server(config-if)#encapsulation ppp                         封装PPP

PPPoE-server(config-if)#ppp authentication chap                   是由CHAP做认证

PPPoE-server(config-if)#peer default ip address dhcp-pool client当对方拨号成功后 使用 这个地址池client  做一个分发

PPPoE-server(config-if)#ip mtu 1492做以一个优化    因为PPPoE会额外的添加8字节的开销，防止超过MTU导致丢包

PPPoE-server(config-if)#no shutdown

PPPoE-server(config-if)#ip add 100.1.1.254 255.255.255.0接口配置地址

PPPoE-server(config-if)#no shutdown

PPPoE-server(config-if)#ex

PPPoE-server(config)#bba

PPPoE-server(config)#bba-group pppoe global                  起一个BBA组  使用 global

PPPoE-server(config-bba-group)#

PPPoE-server(config-bba-group)#virtual-template 1               调用virtual-template 1

PPPoE-server(config-bba-group)#ex

PPPoE-server(config)#int e0/0

PPPoE-server(config-if)#pppoe enable group global调用 BBA组

PPPoE-server(config-if)#

 

 

pppoe-client(config)#vpdn enable 

pppoe-client(config)#int dialer 1                            创建dialer口

pppoe-client(config-if)#dialer pool 100起拨号池 100  一定要一致

pppoe-client(config-if)#encapsulation ppp                   封装PPP

pppoe-client(config-if)#ppp chap hostname admin出示用户名

pppoe-client(config-if)#ppp chap password cisco

pppoe-client(config-if)#ip add negotiated拨号完成后去请求地址

pppoe-client(config-if)#ip mtu 1492

pppoe-client(config-if)#ppp ipcp route default指定缺省路由去往对方 

pppoe-client(config-if)#no shutdown

pppoe-client(config-if)#ex

pppoe-client(config)#int e0/0

pppoe-client(config-if)#no shutdown

pppoe-client(config-if)#pppoe-client dial-pool-number 100   关联和拨号池一致

pppoe-client(config-if)#

*Aug 28 06:23:14.064: %DIALER-6-BIND: Interface Vi1 bound to profile Di1

*Aug 28 06:23:14.070: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up

现在提示日志一个拨号口已经起来了

已经拿到了地址

此次仅为同学们演示思科PPPoE实验。
