# 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.
IV. Configuration verification
After the above configurations, the ISATAP host can access the host in the IPV6
network.

3.7 Troubleshooting Tunneling Configuration
Symptom: After the configuration of related parameters such as tunnel source address,
tunnel destination address, and tunnel type, the tunnel interface is still not up.
Solution: Follow the steps below:
