Este documento mostra a criptografia hub e spoke de um roteador (o hub) para três outros roteadores (os spokes). Não existe um mapa de criptografia no roteador hub que especifique as redes atrás de cada um de seus três peers. Os mapas de criptografia em cada um dos roteadores spoke especificam a rede atrás do roteador de hub.
A criptografia é feita entre estas redes:
Rede 160.160.160.x para rede 170.170.170.x
Rede 160.160.160.x para rede 180.180.180.x
rede 160.160.160.x para rede 190.190.190.x
Não existem requisitos específicos para este documento.
As informações neste documento são baseadas nestas versões de software e hardware:
Software Cisco IOS® versão 12.0.7.T ou posterior
Roteadores Cisco 2500
