Serial 2/1 to be forwarded over the link with DLCI of 300 on tunnel interface 4.

View Interface view
Parameter ip: Performs inverse address resolution for IP addresses.
dlci-number: Data link connection identifier number, that is, virtual circuit number,
indicating that the inverse address resolution is performed for this DLCI number
only, ranges from 16 to 1007.
Description Use the
fr inarp command to enable the inverse address resolution of frame relay.
Use the
undo fr inarp command to disable this function.
By default, system permits enabling the frame relay inverse address resolution.
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.
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 disable the inverse address resolution function of all PVCs, the
command undo 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-number parameter is adopted.
By default, inverse address resolution function is enabled on the interface,
including the subinterface, so are the PVCs on the interface. In this case, use undo
fr inarp ip dlci-number command to disable the address solution function on a
virtual circuit. If you use undo fr inarp command to disable the address solution
function on an interface, the function of all the virtual circuits on the interface is
disabled but the fr inarp ip dlci-number command is used to enable address
resolution function on a virtual circuit.
