ISATAP deployment, first of all your PC needs to be a V4/V6 dual-stack PC , then, you need a router that supports ISATAP , ISATAP router can be anywhere in the network, as long as the PC can ping it (of course, you have to know the router the IPv4 address). Then, we can deploy ISATAP on the router , so that the ISATAP dual-stack host in the network can establish an ISATAP tunnel with the ISATAP router when the IPv6 resource needs to be accessed . The ISATAP host is constructed according to the IPv6 prefix delivered by the ISATAP router. Own IPv6 address (this IPv6 address is automatically associated with an ISATAP virtual NIC generated locally on the ISATAP host ) and will be thisThe ISATAP router is set to its own IPv6 default gateway,ccna dumps 2017 download, so that subsequent hosts can access IPv6 resources through this ISATAP router .
