exit
interface ethernet 0/0
no ip address
pppoe enable
pppoe-client dial-pool-number 1
no shutdown //把接口打开

interface Dialer1
ip address negotiated
ip mtu 1492
encapsulation ppp
ppp pap sent-username walkbird password walkbird
dialer pool 1
ip router 0.0.0.0 0.0.0.0 dialer1
2、用cisco路由器做PPPoE Server端配置

no shutdown
interface virtual-template 1
mtu 1492 //PPP头部最大传输单元
ip unnumbered loopback //借用地址
peer default ip address pool pppoe_ip_pool
encapsulation ppp
ppp authentication pap
exit
ip local pool pppoe_ip_pool 11.11.11.10 11.11.11.100
