Cisco设备上PPPOE实现
实验目的：pppoe在思科设备上实现
实验拓扑：
debug pppoe event 查看pppoe事件。
服务端配置：
bba-group pppoe CCIE //创建pppoe模板
virtual-template 10 //创建vir接口
!
interface Ethernet0/1
pppoe enable group CCIE //接口开启pppoe关联模板
!
interface Virtual-Template10 //进入vir接口
mtu 1492 //修改mtu值
ip address 200.100.5.2 255.255.255.252 //配置接口地址
peer default ip address pool PPP //配置邻居从该地址池获取IP
ppp authentication chap //配置chap认证
!
username ccie password 0 cisco //本地创建用户名和密码
!
ip local pool PPP 200.100.5.1 //配置本地的地址池
客户端配置：
interface Ethernet0/1
pppoe enable //开启pppoe
pppoe-client dial-pool-number 1 //配置为客户端关联dial接口
!
interface Dialer1
mtu 1492 //修改MTU值
ip tcp adjust-mss 1452 //修改MSS值
ip address negotiated //地址通过自动协商获取
encapsulation ppp //接口封装ppp
dialer pool 1
ppp chap hostname ccie //配置用户名
ppp chap password 0 cisco //配置密码
验证：
R1#ping 200.100.5.2 sou dialer 1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 200.100.5.2, timeout is 2 seconds:
Packet sent with a source address of 200.100.5.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 5/8/15 ms
