Frame Relay Configuration Commands 305
For the related command, see fr switching.
Example
Configure a static route that allows packets on the link with DLCI of 100 on
Seiral1/0/0 to be forwarded via the link with DLCI of 200 on interface Serial2/0/0.
[3Com-Serial1/0/0] fr dlci-switch 100 interface serial2/0/0 dlci 200
Configure a static route that allows packets on the link with DLCI of 200 on
Seiral4/1/2 to be forwarded via the link with DLCI of 300 on Tunnel interface
Serial4/0/0.
[3Com-Serial4/1/2] fr dlci-switch 200 interface Tunnel4/0/0 dlci 300
fr inarp
Syntax
fr inarp [ ip ] [ dlci ]
undo fr inarp [ ip ] [ dlci ]
View
Interface view
Parameter
Ip: Indicates that the inverse address resolution is performed on the ip network
protocol.
dlci: Data link connection identifier number, i.e., virtual circuit number, indicating
that the inverse address resolution is performed for this DLCI number only.
Description
Using the fr inarp command, you can enable the inverse address resolution of
Frame Relay. Using the undo fr inarp command, you can 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 enable the inverse address resolution function in the specified
data link, the command with dlci parameter is adopted.
