Restore the default of the time interval for the bundle
link to send Hello messages

successively
Restore the default value of the number of times that
the Frame Relay bundle link waits for the acknowledge

Set the time that the Frame Relay bundle link waits for
the remote end to acknowledge the Hello message
Restore the default number of the time that the Frame
Relay bundle link waits for the remote end to
acknowledge the Hello message
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.
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.
1 Configure 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
Enable Frame Relay compression
Disable Frame Relay compression
By default, Frame Relay payload compression is disabled.
On the 3Com Router, only the Frame Relay sub-interfaces can be point-to-point
interfaces.
