# By comparison, it is found that the host acquires the address prefix 2001::/64 and automatically

generates the address 2001::5efe:2.1.1.2. Meanwhile, “uses Router Discovery” is displayed, indicating

that the router discovery function is enabled on the host. At this time, ping the IPv6 address of the tunnel

interface of the switch. If the address is successfully pinged, an ISATAP tunnel is established.
