Introdução

Uma Rede Virtual Privada de Discagem (VPDN) permite que um serviço de discagem de rede privada se estenda até os servidores de acesso remoto (definidos como o L2TP Access Concentrator [LAC]). Quando um cliente de PPP (Protocolo Ponto-a-Ponto) disca para um LAC, o LAC determina que deve encaminhar aquela sessão de PPP para um LNS (Servidor de Rede L2TP) para aquele cliente, que, em seguida, autentica o usuário e inicia a negociação de PPP. Uma vez que a instalação do PPP esteja concluída, todas os quadros são enviados pelo LAC para o cliente e o LNS.

Esta configuração de exemplo permite que você use a autenticação RADIUS com VPDN. O LAC pergunta o servidor Radius, determina que LNS para enviar o usuário, e estabelece o túnel apropriado.

Para obter mais informações sobre dos VPDN refira a compreensão do VPDN.

Pré-requisitos

Requisitos

Não existem requisitos específicos para este documento.

Componentes Utilizados

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

  • Versão UNIX 2.x.x do Cisco Secure ACS e mais tarde ou radius da merit

  • Software Release 11.2 e Mais Recente de Cisco IOS®

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.

Convenções

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

Informações de Apoio

Neste exemplo, o usuário é “jsmith@hp.com” com senha “teste”. Quando “jsmith@hp.com” disca no roteador ISP, o roteador ISP envia o “hp.com” userid ao servidor Radius ISP. O servidor ISP encontra a id de usuário de "hp.com" e envia seu id de túnel ("isp"), o endereço IP do roteador home gateway (HGW) (10.31.1.50), a senha NAS (Servidor de acesso de rede) ("saudação") e a senha de gateway ("lá") de volta ao roteador ISP.

O roteador ISP inicia um túnel e conecta a 10.31.1.50 o roteador de HGW, que autentica o usuário “HP-GW” localmente e para a frente a senha para userid “isp” (“olá!”) ao servidor Radius HGW. Uma vez que os túneis são estabelecidos, o roteador ISP para a frente ao roteador de HGW, e o userid (“jsmith@hp.com ") e a senha (“teste”) do usuário que disca neste usuário estão autenticados no servidor HGW. Neste exemplo, o roteador ISP é chamado “coala” e o roteador de HGW é chamado “sneetches”.
