# A link-local address (fe80::5efe:2.1.1.2) in the ISATAP format was automatically
generated for the ISATAP interface. Configure the IPv4 address of the ISATAP switch
on the ISATAP interface.

# 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 Switch
Discovery” is displayed, indicating that the switch 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.
