Dit document bevat informatie om inzicht te krijgen in de softwareoplossingen van Cisco IOS wanneer de hoofdmodus en de voorgedeelde toets (PSK) worden gebruikt.
Dit document bevat ook informatie over de manier waarop u bepaalde bug-lijnen in een configuratie kunt vertalen.
Deze onderwerpen worden niet besproken:
IKE en IPSec debugs hebben de neiging cryptisch te worden. Cisco Technical Assistance Center (TAC) gebruikt deze insecten vaak om te begrijpen waar een probleem met de vestiging van de IPSec VPN-tunnel zich bevindt.
De hoofdmodus wordt doorgaans gebruikt tussen LAN-to-LAN tunnels, of in het geval van externe toegang (ezvpn) wanneer certificaten worden gebruikt voor verificatie.
Deze apparaten komen van een Cisco IOS apparaat dat de 15.2(1)T softwarerelease in werking stelt.
In dit document worden twee hoofdscenario's beschreven:
In dit document wordt een op VTI gebaseerde tunnel tussen twee locaties opgezet, gebaseerd op IPv6.
