Frame relay compression technique can be used to compress frame relay packets 
to save network bandwidth, reduce network load and improve the data transfer 
efficiency on frame relay network.

Routers support FRF.9 (FRF.9 stac compression).

FRF.9 classifies packets into two types: control packet and data packet. Control 
packets are used for status negotiation between the two ends of DLCI where 
compression protocol has been configured. Only after the negotiation succeeds 
can FRF.9 data packets be switched. If FRF9 control packets are sent more than 
certain times and negotiation still can not succeed, negotiation will stop and 
compression configuration does not work.

FRF.9 only compresses data packets and Inverse ARP packets, excluding LMI 
packets.

Frame relay main interface is a point-to-multipoint interface, while frame relay 
sub-interface includes two types: point-to-point interface and point-to-multipoint 
interface. Therefore, the configuration of frame relay compression includes:

■

Configuration of point-to-point frame relay compression

■

Configuration of point-to-multipoint frame relay compression

Perform the following configuration in Interface View.

By default, frame relay compression function is disabled.
