Este documento apresenta um exemplo de configuração para um roteador com várias interfaces BRI que disca para outro roteador com várias interfaces BRI e estabelece uma conexão PPP Multilink (MPPP - Multilink PPP). O roteador que disca deve identificar se não há mais canais disponíveis na BRI remota e, em seguida, discar o próximo número de telefone BRI remoto para estabelecer os canais adicionais.
Ambos os roteadores usam perfis de discador para ligar as interfaces BRI físicas. Você também pode configurar essa configuração com um grupo de giro do discador conforme descrito em Configurando o MPPP para várias BRIs usando grupos rotativos.
Para obter mais informações sobre perfis de discador, consulte Configuração e Troubleshooting de Perfis de Discador.

Observe estes pontos na configuração do Cisco 3640 (melanie):
A configuração usa perfis de discador. As interfaces BRI são membros de um pool de discadores. Todas as configurações específicas do destino são configuradas na configuração do discador de interface 2.
A interface do discador tem duas cadeias de caracteres do discador. Lembre-se de que há duas interfaces BRI no roteador remoto (torito). Como essas BRIs não foram configuradas em um grupo de busca pela Telco, a melanie do roteador deve discar cada BRI individualmente. Com várias sequências de caracteres de discador, o primeiro número de telefone é sempre discado. Somente se essa chamada falhar a interface do discador tentará a segunda string do discador. Podemos definir quantas sequências de caracteres do discador forem necessárias como forem usadas em ordem sequencial.
O limite de carga do discador para MPPP é definido como um, que é o mínimo. Esse valor pode ser alterado com base em seus padrões e requisitos de tráfego. No entanto, se você definir um limite de carga mais alto, os links adicionais só serão adicionados quando houver uma carga além dessa definição. Consulte a seção Ajuste e Comandos Opcionais para obter mais informações sobre como controlar a adição de canais ao pacote multilink.
A rota de host estática para o roteador remoto aponta para a interface dialer 2. O tráfego é encaminhado pelos membros físicos do pool (BRI 2/1 e BRI 2/2). Crie uma rota estática (ou use um protocolo de roteamento) para o tráfego de destino que deve usar a conexão multilink.

Você pode usar os comandos nesta seção para ajustar o comportamento da conexão MPPP. Você pode controlar os custos com o ajuste cuidadoso desses parâmetros, o que ajuda a evitar o uso inútil e desnecessário de enlaces de dados. Esses comandos devem ser implementados no lado que inicia a discagem.
dialer load-threshold load[outbound | entrada | ou]???Você pode configurar o MPPP para que os canais adicionais sejam ativados imediatamente após o canal principal ser estabelecido. Nesse caso, defina o valor de limite de carga no comando dialer load-threshold load como 1. Portanto, os canais adicionais são criados e eles continuam ativos (ou seja, não oscilam). Se o limiar de carga for definido para um valor mais alto, os vários canais podem oscilar, com base na carga através do link. Se desejar que canais adicionais sejam adicionados conforme necessário, com base no tráfego, defina o limite de carga para o valor apropriado entre 1 e 255. Por exemplo, se os canais adicionais devem atingir 50% da capacidade total, o limite deve ser definido como 128 (0,50*255).
ppp timeout multilink link remove seconds ????Use este comando para evitar que as conexões multilink oscilem quando a carga varia. Por exemplo, quando o limite de carga é definido como 15 (ou seja, 15/255 = 6%) e o tráfego excede o limite, linhas adicionais são ativadas. Quando o tráfego fica abaixo do limite, as linhas adicionais são descartadas. Em situações em que as taxas de dados são altamente variáveis, para canais múltiplos, é vantajoso ficar ativo por um período específico de tempo, mesmo quando o limite de carga fica abaixo do valor especificado. Atribua a este intervalo de multilink um tempo menor que o especificado para o intervalo de discador ocioso que controla o intervalo de todos os links.
ppp timeout multilink link add seconds ????Use este comando para impedir a adição de vários links ao pacote MP até que o tráfego alto seja recebido para um intervalo especificado. Isso pode impedir que rajadas de tráfego ativem linhas adicionais desnecessariamente.
dialer max-link number ????Para especificar, para um perfil de discador, o número máximo de links para um destino remoto que pode estar ativo a qualquer momento, use o comando dialer max-link no modo de configuração de interface. Neste exemplo, temos duas BRIs (ou quatro canais B) em melanie configuradas para discagem. Portanto, todos os quatro canais, por padrão, são ativados em uma conexão MPPP. No entanto, se quiser que apenas três canais B sejam ativados, você pode usar o comando dialer max-link para restringir o número de links.
Esta seção fornece informações que você pode usar para confirmar se sua configuração está funcionando adequadamente.
Use estes comandos para verificar a conexão:
A Output Interpreter Tool (somente clientes registrados) oferece suporte a determinados comandos show, o que permite exibir uma análise da saída do comando show.
show isdn status????indica se o roteador se comunica corretamente com o switch ISDN. Na saída, você precisa verificar se o Status da Camada 1 está ATIVO, e se o Estado de Status da Camada 2 = MULTIPLE_FRAME_ESTABLISHED é exibido. Esse comando exibe também o número de chamadas ativas. Para obter mais informações, consulte Utilização do Comando show isdn status para Troubleshooting de BRI.
show ppp multilink????exibe informações sobre pacotes multilink ativos. Use esse comando para verificar a conexão multilink.
show dialer [interface type number]???exibe informações gerais de diagnóstico para interfaces configuradas para DDR. Se o discador foi ativado corretamente, a mensagem Dialer state is data link layer up (O estado do discador é a camada de enlace de dados ativa deve aparecer. Se a camada física acima aparecer, significa que o protocolo de linha foi ativado, mas o Network Control Protocol (NCP) não. Os endereços de origem e destino do pacote que iniciou a discagem são mostrados na linha de razão de discagem. Este comando show também exibe a configuração do temporizador e o tempo antes do tempo limite da conexão.
show caller user username detail???mostra parâmetros para o usuário específico, como o endereço IP atribuído, parâmetros de pacote PPP e PPP e assim por diante. Se a sua versão do Cisco IOS não suportar este comando, use o comando show user.
O comando show ppp multilink mostra os membros do pacote multilink em cada roteador após a conexão dos links. Observe que no roteador melanie, o nome do pacote é torito enquanto no roteador torito o nome do pacote é melanie. As interfaces BRI e os canais B que pertencem ao pacote também são indicados.

Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.
Observação: antes de emitir comandos debug, consulte Informações importantes sobre comandos debug.
debug dialer????exibe informações de depuração DDR sobre os pacotes recebidos em uma interface de discador. Essas informações podem ajudar a garantir que haja tráfego interessante que possa usar a interface do discador.
debug isdn q931???mostra a configuração de chamada e a desconexão da conexão de rede ISDN (Camada 3).
debug ppp negotiation????exibe informações sobre o tráfego PPP e trocas enquanto negocia o LCP (Link Control Protocol, protocolo de controle de link), a autenticação e o NCP (Network Control Protocol, protocolo de controle de rede). Uma negociação de PPP bem-sucedida abrirá primeiramente o estado do LCP e, em seguida, autenticará e, finalmente, negociará o NCP. Os parâmetros de multilink, como a unidade de recepção máxima reconstruída (MRRU), são estabelecidos quando a negociação de LCP está em andamento.
debug ppp authentication????exibe mensagens do protocolo de autenticação PPP e inclui trocas de pacotes CHAP e PAP (Password Authentication Protocol).
debug ppp error???exibe erros de protocolo e estatísticas de erro associadas à negociação e operação da conexão PPP.
Para obter informações sobre como solucionar problemas de multilink por BRI, consulte Troubleshooting de Falhas de Chamadas do Segundo Canal B em Links ISDN BRI. Quando você tiver multilink funcional em 1 BRI (2 canais b), poderá adicionar BRIs ao pacote.
Ative as depurações descritas na seção Comandos de Troubleshooting e, em seguida, faça ping no endereço do roteador remoto. O ping deve iniciar a discagem e se conectar ao roteador remoto. À medida que cada link adicional é ativado, ele é adicionado ao pacote MPPP.
