Cisco 1841 suporte a PPPOE service-name

Boa tarde,

Estou precisando de uma config exemplo para conectar a um servidor PPPOE que necessita obrigatoriamente de um service-name.

Estou tentando configurar num roteador CISCO 1841.
Com a config abaixo consigo conectar, autentico porém como não enviei o service-name um outro servidor me envia as configurações.
