Esta configuração de exemplo mostra um projeto do IPsec de hub e spoke entre três roteadores. Essa configuração difere das outras configurações de hub e spoke devido à comunicação, neste exemplo, estar habilitada entre sites spoke por meio da passagem pelo hub. Ou seja, não há um túnel de IPsec direto entre os dois roteadores do spoke. Todos os pacotes são enviados pelo túnel para o roteador do hub, onde os redistribui para fora do túnel de IPsec compartilhado com outro roteador de spoke. Essa configuração é possível como resultado da resolução para o bug da Cisco ID CSCdp09904 (somente clientes registrados) . Esta correção foi integrada no Cisco IOS® Software Release 12.2(5) e esta versão tem os requisitos mínimos para esta configuração.
Para configurar o túnel GRE sobre IPSec com OSPF, consulte Configuração de um Túnel GRE sobre IPSec com OSPF.
Para configurar a configuração básica do Cisco IOS® Firewall em um túnel GRE com Network Address Translation (NAT), consulte Configuração de IPSec de Roteador para Roteador (Chaves Pré-compartilhadas) no túnel GRE com Firewall IOS e NAT.
Este documento requer uma compreensão básica do protocolo de IPSec. Consulte Uma Introdução à Criptografia IP Security (IPSec) para saber mais sobre o IPsec.
O objetivo deste documento é garantir que a criptografia seja feita entre estes roteadores:
172.16.1.0/24 (Spoke 1) a 10.1.1.0/24 (Hub)
192.168.1.0/24 (Spoke 2) a 10.1.1.0/24 (Hub)
172.16.1.0/24 (Spoke 1) a 192.168.1.0/24 (Spoke 2)
As informações neste documento são baseadas nestas versões de software e hardware.

Se você precisar adicionar outro roteador spoke (spoke3) ao roteador hub existente além de spoke1 e spoke2, tudo o que é necessário é a criação de um novo túnel LAN a LAN (L2L) do hub para spoke3. No entanto, como apenas um mapa de criptografia pode ser configurado por interface física, você deve usar o mesmo nome de mapa de criptografia ao adicionar esse túnel. Isso é possível quando você usa números de linha diferentes para cada local remoto.
Observação: o mapa de criptografia pode precisar ser removido e reaplicado à interface quando a nova entrada de túnel for adicionada. Quando o mapa de criptografia é removido, todos os túneis ativos são removidos.

Use esta seção para confirmar se a sua configuração funciona corretamente.
A Output Interpreter Tool ( somente clientes registrados) (OIT) oferece suporte a determinados comandos show. Use a OIT para exibir uma análise da saída do comando show.
Para verificar essa configuração, tente um comando ping estendido originado do endereço da interface ethernet1 no Spoke 1, destinado ao endereço da interface ethernet1 no Spoke 2.
ping —Usado para diagnosticar a conectividade básica da rede.

show crypto ipsec sa —Mostra as configurações usadas pelas associações de segurança (SAs) atuais (IPSec).
show crypto isakmp sa —Mostra todas as SAs IKE atuais em um peer.
show crypto engine connections ative — Mostra o número de pacotes transmitidos através de cada IPSec SA.
Esta saída é do comando show crypto engine connections ative emitido no roteador Hub.

Neste exemplo, você pode ver que cada túnel criptografou e descriptografou 10 pacotes, o que prova que o tráfego passou pelo roteador Hub.
Observação: duas SAs IPsec são criadas para cada peer (uma em cada direção). Por exemplo, no roteador de hub há quatro SAs IPsec criadas para dois pares.
Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.

debug crypto ipsec —Mostra as negociações de IPsec da fase 2.
debug crypto engine —Mostra o tráfego que está criptografado.
clear crypto isakmp —Limpa as SAs relacionadas à fase 1.
