RÉSEAU LOCAL de base du flexible VPN à la configuration LAN
L'installation d'un RÉSEAU LOCAL de base au RÉSEAU LOCAL entre deux points finaux d'IPv6 n'est pas différente que l'ipv4.
Stratégie de la proposition IKEv2, de la stratégie et de l'autorisation
Les par défaut intelligents (stratégie de proposition IKEv2, de stratégie et d'autorisation) sont utilisés dans cet exemple.
Note: Des par défaut intelligents ne doivent pas être configurés.

Création de l'interface de tunnel utilisant le sVTi
Puisque deux types de trafic différents peuvent être utilisés, l'ipv4 et l'IPv6 au-dessus de l'IPv6 existant percent un tunnel, vous ont différentes conceptions comme :
-
IPv6 dans le tunnel d'IPv6 utilisant l'IPv6 d'ipsec de tunnel mode
-
Ipv4 dans le tunnel d'IPv6 utilisant l'IPv6 de tunnel mode gre
-
mode hybride où vous faites l'ipv4 et l'IPv6 par un tunnel utilisant l'IPv6 de tunnel mode gre
Note: Les administrateurs d'il est recommandé que utilisent des tunnels GRE au-dessus de SVTIs (mode d'IPSec). C'est parce que dans la plupart d'IPv6 de déploiements le support implique réellement la double pile et GRE/IPSEC prend en charge la double pile sans faille.
