配置如下

R1(config)#int e1/0

R1(config-if)#ip add 172.16.99.2 255.255.0.0

R1(config-if)#end

R1#show ip int

*Mar  1 00:05:11.435: %SYS-5-CONFIG_I: Configured from console by console

R1#show ip int bri

R1#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

R1(config)#int e1/0

R1(config-if)#p?

pagp  pppoe  pppoe-client  priority-group

 

R1(config-if)#pp

R1(config-if)#pppoe ?

  enable  Enable pppoe

 

R1(config-if)#pppoe en

R1(config-if)#pppoe enable     打了这条命令也可以          

R1(config-if)#exit

R1(config)#int virtual-Template 1

R1(config-if)#ppp authentication ms-chap            

R1(config-if)#peer default ip address pool vpndhcp     这里少这一条命令，后面补上了

R1(config-if)#encapsulation ppp                                    

R1(config-if)#ip address 192.1.1.1 255.255.255.0

R1(config-if)#no shu

R1(config-if)#exit

R1(config)#ip local

R1(config)#ip local pool vpndhcp 192.1.1.2 192.1.1.5

R1(config)#int lo 0

R1(config-if)#ip add 192.1.1.6 255.255.255.0

% 192.1.1.0 overlaps with Virtual-Template1

R1(config-if)#exit

R1(config)#vpdn en

R1(config)#vpdn enable

R1(config)#vpdn-group 1

R1(config-vpdn)#accept-dialin

R1(config-vpdn-acc-in)#protocol ?

  any    Use any protocol

  l2f    Use L2F

  l2tp   Use L2TP

  pppoe  Use PPPoE

  pptp   Use PPTP

 

R1(config-vpdn-acc-in)#protocol pptp

R1(config-vpdn-acc-in)#exit

R1(config-vpdn)#^Z

R1(config)#int virtual-template 1

R1(config-if)#peer default ip address pool vpndhcp  

R1(config-if)#exit
