The default link identification is the name of its physical interface.

By default, a bundle link will send out hello message every 10 seconds; it will send a hello message a maximum of 3 times and wait 4 seconds for a hello message acknowledgement.

Payload Compression

(FRF.9)

Introduction to Frame Relay Payload Compression

Using the Frame Relay payload compression technique to compress Frame Relay packets can effectively save the network bandwidth, and reduce the network load, hence fulfilling the highly efficient data transmission over the Frame Relay networks.

The 3Com Routers adopt FRF.9 standard to implement Frame Relay payload compression. When applied to the Frame Relay lines with relatively low bandwidth, Frame Relay payload compression can achieve significant effect.

Frame Relay Compression Configuration

Frame Relay interfaces fall into two types: point-to-point interface and multipoint interface. The methods of configuring Frame Relay payload compression are different for these two types of interfaces.

1Configure Frame Relay payload compression on point-to-point interface Perform the following configurations in interface view.

Table 295 Configure Frame Relay compression on point-to-point interface

Compression	Command
Enable Frame Relay compression	fr compression frf9
Disable Frame Relay compression	undo fr compression frf9

By default, Frame Relay payload compression is disabled.

On the 3Com Router, only the Frame Relay sub-interfaces can be point-to-point interfaces.
