Introduction

Este documento fornece uma configuração de exemplo para o uso do bridging intermediário PPP para conectar redes roteadas e interconectadas.

Prerequisites

Requirements

Não existem requisitos específicos para este documento.

Componentes Utilizados

As informações neste documento são baseadas nestas versões de software e hardware:

  • Software Cisco IOS® versão 12.2(7b).

  • Dois roteadores da série Cisco 2500. Cada uma tem pelo menos uma interface ISDN BRI.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Produtos Relacionados

Esta configuração também pode ser utilizada com estas versões de hardware e software:

  • Qualquer interface serial, como serial, BRI (Basic Rate Interface Interface de Taxa Básica), PRI (Primary Rate Interface Interface de Taxa Primária) e assim por diante.

  • Software Cisco IOS versão 11.2.

  • Qualquer roteador executando o software Cisco IOS conforme mencionado acima e pelo menos uma porta ISDN-BRI. No entanto, o recurso de meia ponte pode ser usado em um roteador com uma interface serial.

Conventions

Para obter mais informações sobre convenções de documento, consulte as Convenções de dicas técnicas Cisco.

Informações de Apoio

A ponte envia pacotes de ponte para a meia-ponte PPP que os converte em pacotes roteados e os encaminha para outros processos do roteador. Da mesma forma, a meia-bridge PPP converte pacotes roteados em pacotes de bridge Ethernet e os envia à bridge na mesma sub-rede Ethernet.

Observação: essa configuração não cobre uma bridge completa em ambos os lados. Para tal configuração, consulte o documento Bridging Across ISDN.

Esteja ciente de que o Bridging em uma conexão ISDN tende a manter a conexão ativa por períodos muito longos, se não permanentemente. Se a Telco cobrar por ISDN com base no tempo de conexão, isso pode resultar em uma conta muito grande. Consequentemente, esse cenário é recomendado para aqueles que têm linhas ISDN de uso ilimitado.

Observação: uma interface não pode funcionar como uma meia ponte e uma bridge. O software Cisco IOS não suporta mais de uma meia ponte PPP por sub-rede Ethernet.

Configurar

Nesta seção, você encontrará informações para configurar os recursos descritos neste documento.

Observação: para encontrar informações adicionais sobre os comandos usados neste documento, use a ferramenta Command Lookup Tool (somente clientes registrados).

Diagrama de Rede

Este documento utiliza a seguinte configuração de rede:

ppp_half_bridging.gif

Configurações

Este documento utiliza as seguintes configurações:

  • Vênus

    Esse roteador está configurado como uma bridge completa com o roteamento IP desabilitado. O dispositivo disca quando qualquer tráfego de ponte chega.

  • Saturno

    Este roteador foi configurado como uma meia ponte. Observe que os comandos dialer string, dialer group e dialer list não estão configurados nesse lado. Assim, esse roteador nunca discará, mas aceitará chamadas recebidas. Isso impede que o roteador disque para o roteador remoto. Ativamos o roteamento IP aqui. O software Full Bridging não está configurado neste roteador. A meia ponte PPP está sendo executada na interface BRI, portanto comandos como show bridge e show spanning-tree não produzem nenhuma saída neste roteador.

Troubleshoot

Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.

Troubleshooting de Recursos

Os procedimentos de Troubleshooting para chamadas ISDN de entrada e saída são explicados na Tecnologia de Discagem: Documento Técnicas de Troubleshooting. Informações adicionais sobre como solucionar problemas das camadas 1, 2 e 3 da ISDN são fornecidas em Using the show isdn status Command for BRI Troubleshooting and Troubleshooting ISDN BRI Layer 3 usando o Comando debug isdn q931.

Comandos para Troubleshooting

A Output Interpreter Tool (somente clientes registrados) oferece suporte a determinados comandos show, o que permite exibir uma análise da saída do comando show.

Observação: antes de inserir o comando debug, consulte Informações importantes sobre os comandos debug.

  • debug dialer —indica quando o tráfego interessante foi detectado e quando a discagem foi iniciada.

  • debug isdn event — indica que a atividade ISDN está ocorrendo no lado do usuário da interface ISDN e é semelhante à debug isdn q931.

  • debug isdn q931 —fornece informações sobre a configuração de chamadas e a desconexão de conexões de rede ISDN (Camada 3), entre o roteador local (lado do usuário) e a rede.

  • debug isdn q921 —exibe os procedimentos de acesso da camada de enlace (Camada 2) que estão ocorrendo no roteador no canal D (LAPD) de sua interface ISDN.

  • debug ppp negotiation —executa a negociação de opções PPP e parâmetros do Network Control Protocol (NCP).

  • debug ppp authentication —permite a troca de pacotes Challenge Authentication Protocol (CHAP) e Password Authentication Protocol (PAP).
