pppoe cliente y servidor

Vamos a ver la configuración del cliente y del servidor para establecer una sesión pppoe siendo R1 el servidor y R2 el cliente

La configuración del servidor mínima consta de lo siguiente:

Nombre y clave para la autenticación del cliente

username R2 password 0 CISCO

Servidor DHCP (de alguna forma hay que dar ip al lciente)

ip dhcp pool MYPOOL
   network 10.0.0.0 255.255.255.0
ip dhcp excluded-address 10.0.0.1

Un BBA group y su virtual template correspondiente (con la ip asignada a la fa0/0)

bba-group pppoe 1
 virtual-template 1
interface Virtual-Template1
 ip address 10.0.0.1 255.255.255.0

Lo aplicamos a la fa0/0

interface FastEthernet0/0
 no ip address
 pppoe enable group 1
end

La configuración del cliente sería la siguiente:
Interfaz física

interface FastEthernet0/0
 no ip address
 pppoe enable group global
 pppoe-client dial-pool-number 1
end

Dialer

interface Dialer0
 ip address dhcp
 encapsulation ppp
 dialer pool 1
 ppp authentication pap callin     ! autenticación clinete-servidor
 ppp pap sent-username R2 password 0 CISCO
end

Ejecutando el comando who sobre el cliente podemos ver la sesión establecida:

R2#who
    Line       User       Host(s)              Idle       Location
