Confirmation of interface state and routing state

Ver. 07-02
5.2 Confirmation of IPv4 network state
This section describes the confirmation of an interface in which an IPv4 address is
specified using a configuration definition command (ip).
5.2.1 Confirming the up/down state of interface
After an IPv4 address is set to the line of the router, connected to an IPv4 network, or
the port in a line, execute a show ip interface command and confirm that the up/
down state of an IPv4 interface is "up".
Figure 5-13 Example of display of IPv4 Interface state
See Subsection 7.5.1, “Communication cannot be done or communication is
disconnected” when an interface is in the down state.
5.2.2 Confirming the communication with relevant destination address
Confirm using a ping command whether the interface of the router connected to an
IPv4 network can communicate with the router used as a communication peer.
