Dit document toont hub en sprak encryptie van één router (het "hub") aan drie andere routers (de "spokes"). Er is één crypto kaart op de hub router die de netwerken achter elk van zijn drie peers specificeert. De crypto kaarten op elk van de gesproken routers specificeren het netwerk achter de hub router.
Er wordt versleuteld tussen deze netwerken:
160.160.160.x-netwerk tot 170.170.170.x-netwerk
160.160.160.x-netwerk tot 180.180.180.x-netwerk
160.160.160.x-netwerk tot 190.190.190.x-netwerk
Er zijn geen specifieke vereisten van toepassing op dit document.
De informatie in dit document is gebaseerd op de volgende software- en hardware-versies:
Cisco IOS® softwarerelease 12.0.7.T of hoger
Cisco 2500 routers
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.
Raadpleeg voor meer informatie over documentconventies de technische Tips van Cisco.
Deze sectie bevat informatie over het configureren van de functies die in dit document worden beschreven.
