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 TACACS+ com redes dial-up privadas virtuais (VPDN). O LAC pergunta o server TACACS+, determina que LNS para enviar o usuário, e estabelece o túnel apropriado.
Para obter mais informações sobre dos VPDN, refira a compreensão do VPDN.

Esta seção apresenta a informação necessária configurar as características descritas neste documento.
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 server ISP TACACS+. 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-o ao roteador de HGW, que para a frente as senhas para userid “HP-GW” (“lá”) e então userid “isp” (“olá!”) ao server HGW TACACS+. Uma vez que os túneis são estabelecidos, o roteador ISP para a frente ao roteador de HGW o userid (“jsmith@hp.com ") e senha (“teste”) do usuário que disca dentro. Este usuário é autenticado no servidor HGW. Nas configurações de amostra neste documento, o nome de host do roteador ISP é “coala” e o nome de host do roteador de HGW é “thing_one”.
