Este documento explica como suportar um Protocolo Ponto a Ponto pelo Cliente Ethernet (PPPoE) em roteadores com Cisco IOS® conectados por uma interface Ethernet a um modem DSL ou ao equipamento das premissas (CPE) DSL de outro fornecedor.
Os ISP fornecem frequentemente seus clientes um modem DSL que tenha uma interface Ethernet a conectar ao segmento de Ethernet do cliente, e uma outra relação para a conectividade de linha DSL. Em tal caso, o modem DSL atua somente como uma ponte se o CPE não é configurável para nenhuns conectividade IP ou recursos aprimorado sobre o DSL. Isto limita sua conectividade para apenas um PC Cliente de PPPoE. Com a adição de um roteador do Cisco IOS conectado aos Ethernet do modem DSL, você pode executar a característica do PPPoE Client IO no roteador Cisco. Isto pode conectar PC múltiplos no segmento de Ethernet conectado ao roteador do Cisco IOS. Com o uso do Cisco IOS roteador, você pode aumentar suas conectividades de DSL e todas as características IO, tais como a Segurança, o Network Address Translation (NAT) e o protocolo de configuração dinâmica host (DHCP) aos host internos.
O recurso PPPoE permite que você inicialize uma sessão PPP em um cliente de Bridging Ethernet simples conectado. As sessões são transportadas pelo enlace ATM por meio de molduras transpostas de Ethernet encapsuladas. Você pode terminar a sessão em um escritório central da portadora de intercâmbio local ou em um Point of Presence ISP.
Não existem requisitos específicos para este documento.
As informações neste documento são baseadas nestas versões de software e hardware:
IOS Software release 12.1(1)XB do Cisco 827-4V CPE
Cisco 2611 Router que executa uma imagem do Cisco IOS Software Release 12.2(2)T1
Concentrador de acesso universal (UAC) do Cisco 6400 que executa uma imagem do Cisco IOS Software Release 12.1(5)DC1
As informações neste documento foram criadas a partir de dispositivos em um ambiente de laboratório específico. Todos os dispositivos utilizados neste documento foram iniciados com uma configuração (padrão) inicial. Se a sua rede estiver ativa, certifique-se de que entende o impacto potencial de qualquer comando.

Nesta seção, você é presentado com a informação usada a fim configurar as características descritas neste original.
Nota: Para encontrar informações adicionais sobre os comandos usados neste documento, use a Command Lookup Tool (somente clientes registrados).
Este documento utiliza a configuração de rede mostrada neste diagrama.
Nota: Neste original, a conexão do PPPoE Client é iniciada do roteador Cisco. Esse é o Cisco 2611 Router nessa configuração. O roteador Cisco 827 no diagrama representa o CPE de DSL sem Cisco.
