# The host acquires the address prefix 2001::/64 and has automatically generated the address

2001::5efe:2.1.1.2. The message "uses Router Discovery" indicates that the router discovery

function is enabled on the host. Ping the IPv6 address of the tunnel interface of the router. The ping

operation succeeds, indicating an ISATAP tunnel has been established.

Verifying the configuration

After the configuration, the ISATAP host can access the host in the IPV6 network.

Configuring an IPv4 over IPv4 tunnel

Configuration prerequisites

Configure an IP addresses for the interface (such as a VLAN interface, GigabitEthernet interface, or

loopback interface) to be configured as the source interface of the tunnel interface.
