5.5 Confirmation of IPv6 network state
This section describes the confirmation of an interface in which an IPv6 address is
specified using a configuration definition command (ip).
5.5.1 Confirming the up/down state of interface
After an IPv6 address is set to the line of the router, connected to an IPv6 network, or
the port in a line, execute a show ipv6 interface command and confirm that the up/
down state of an IPv6 interface is "up".
Figure 5-52 Example of display of IPv6 Interface state
See Subsection 7.8.1, “Communication cannot be done or communication is
disconnected” when an interface is in the down state.
5.5.2 Confirming the communication with relevant destination address
Confirm using a ping ipv6 command whether the interface of the router connected to
an IPv6 network can communicate with the router used as a communication peer.

Route Exists))
