Annexe R25. VLAN et VPN
Cette annexe introduit les VPN IP en commençant par les VPN personnels et les VPN de groupe avec identification du trafic. Elle examine ensuite les VPN des réseaux en mode avec connexion, c’est-à-dire les réseaux dans lesquels un paquet ne peut être envoyé qu’après une négociation avec le terminal distant. Les VPN des réseaux ATM et MPLS sont étudiés plus en détail à la section suivante.
Les VPN IP
Les VPN peuvent être implémentés selon six modèles différents. La figure R.1 illustre ces différents modèles. Parmi les nœuds, on trouve les équipements terminaux (End ou End Systems), les CE (Customer Edge) et les PE (Provider Edge). CE et PE sont généralement des routeurs qui se trouvent chez le client ou l’opérateur.
