Step 2 Run:
interface interface-type interface-number.subnumber p2p
The command creates the FR sub-interface view is created and appears. The sub-interface
type is point-to-point.
Step 3 Run:
fr dlci dl ci
The command configures the DLCI.
Step 4 Run:
quit
Return to the FR sub-interface view.
Step 5 Run:
fr compression frf9
The command enablesFR FRF.9 compression.
Before configuring this command, you need to configure the DLCI of the interface.
You configure this command only on the point-to-point FR sub-interface, and the packet
encapsulation type must be IETF. If the packet encapsulation type is nonstandard, and when
you run the command to enable the FR FRF.9 compression, the system prompts that the
nonstandard encapsulation type does not support FRF.9 compression.
CP
NOTE
• The FRF.9 compression is suitable for the low-speed link.
• The MFR link does not use the FRF.9 compression.
• The FRF.9 compression has one synchronization procedure. During the compression, the packets are
in disorder. Usually, the compression does not succeed.

8.9.3 Configuring FR FRF.9 compression on a main-interface or a
point-to-multipoint sub-interface
Do as follows on the routers:
Step 1 Run:
system-view
The system view appears.
Step 2 Choose one of the following steps to enter the corresponding interface view as required.
• Run the interface interface-type interface-number command to enter the FR interface
view.
• Run the interface interface-type interface-number.subnumher p2mp command to enter
the FR P2MP sub-interface view.
