Error en configurar pppoe router ROUTER 880 series ISR CISCO888-k9

Estimados les hago la consulta,

paso 1 - vpdn enable
             - vpdn-group 1
             - request-dialin
             - protocol pppoe
% Invalid input detected at '^' marker.
Solo me permite mediante L2tp y no acepta pppoe segun el help

ROUTER 880 series ISR

CISCO888-k9       ios version 15.3
license udi pid CISCO888-K9 sn FTX181785XJ

¿Sera que debo cambiar el IOS a una version anterior para que este modelo de router soporte ese protocolo pppoe? o es que no es posible en este fierro configurar ese protocolo

gracias de antemano por su respuestas

Dear friend,

Dear friend,

Although I didn't fully understand your question (because it's not written in English), I can suggest that you try the following configuration for bringing up a PPPoE session (it worked for me on a Cisco 880 Series router):

(config)# int dialer 1

(config-if)# desc OUTSIDE_LOGICAL

(config-if)# encap ppp

(config-if)# mtu 1492

(config-if)# ppp pap sent-username <your-username> password <your-password>

(config-if)# ip addr negotiated     (or "ip addr dhcp")

(config-if)# ppp ipcp route default

(config-if)# dialer pool 2

(config-if)# ip nat outside

(config-if)# exit

(config)# int fa 0/0

(config-if)# desc OUTSIDE_PHYSICAL

(config-if)# pppoe-client dial-pool-number 2

(config-if)# no shut

(config-if)# exit

(config)# int fa 0/1

(config-if)# desc INSIDE_PHYSICAL

(config-if)# ip addr

(config-if)# ip nat inside

(config-if)# no shut

(config-if)# exit

(config)# access-list 10 permit

(config)# ip nat inside source list 10 interface dialer 1 overload
If not usnig PAP authentication, remove this line:
(config-if)# ppp pap sent-username <your-username> password <your-password>
instead, put in this line under interface dialer 1:
(config-if)# ppp chap password <your-password>
Hope this helps.
