■ Interface view
Description When the Frame Relay sends data over the interface, it is necessary to map the
network address to the DLCI numbers. Such a map can be specified manually or can
be completed via the function of automatic inverse address resolution. Automatic
inverse address resolution can be started by using the command.
InARP of FR applies to both IP and IPX addresses.
If it is expected to enable the inverse address resolution function of all PVCs, the
command without any parameters is adopted.
If it is expected to enable the inverse address resolution function in the specified data
link, the command with
dlci parameter is adopted.
The fr inarp command configured on an FR main interface also applies to its
subinterfaces.
