PPPoE配置实例

Topology:     PC----CPE----ISP

########################################
PC:--->R1
   hostname PC
   no ip routing
   int f0/0
      ip add dhcp
########################################
CPE:--->R2
配置步骤：
1.启用VPDN：      
        vpdn enable
2.创建dialer0

3.在物理口启用pppoe,并使用dialer0   :  
         pppoe enable 和pppoe-client dial-pool-number 1
4.创建一条默认路由,出口为dialer 0                        
5.配置DHCP
6.配置NAT


hostname CPE
ip dhcp excluded-address 192.168.1.254
!
ip dhcp pool cisco
   network 192.168.1.0 255.255.255.0
   default-router 192.168.1.254

vpdn enable
!
interface FastEthernet0/0
ip address 192.168.1.254 255.255.255.0
ip nat inside
!
interface FastEthernet1/0
no ip address
pppoe enable group global
pppoe-client dial-pool-number 1
!
interface Dialer0
ip address negotiated
ip nat outside
encapsulation ppp
dialer pool 1      //指定此Dialer接口为特定的pool
dialer-group 2     //对特定的流量激活拨号
ppp authentication chap callin
ppp chap hostname cisco
ppp chap password 0 spoto
!
ip route 0.0.0.0 0.0.0.0 Dialer0
!
ip nat inside source list NAT interface Dialer0 overload
!
ip access-list standard NAT
permit 192.168.1.0 0.0.0.255
!         
dialer-list 2 protocol ip permit

ISP:
配置步骤：
1.启用VPDN，并创建vpdn-group
2.在bba-group pppoe global创建virtual-template 1
3.配置virtual-template 1,分配本地地址池，PPP认证，
4.创建本地地址池
5.物理口启用PPPOE
6.创建本地数据库


hostname ISP
vpdn enable
!         
username cisco password 0 spoto  //要创建本地数据库
!
bba-group pppoe global        //Enters BBA group configuration mode and defines a global PPPoE profile.

virtual-template 1 //如果接口下pppoe enable默认是global，没有指定group后参数，那么要先配置PPPoE profile
!
interface Loopback0
ip address 202.1.1.1 255.255.255.0
!
interface FastEthernet1/0
no ip address
pppoe enable group global
!         
interface Virtual-Template1
ip unnumbered Loopback0
peer default ip address pool cisco  //分配IP
ppp authentication chap
!
ip local pool cisco 10.0.0.1 10.0.0.10
