Nortel Secure Router 8000 Series
Configuration -WAN Access 8 Frame relay configuration
The main interface of FR is the point-to-multipoint interface. The sub-interface has the P2P
interface and the P2MP interface. FR compression includes configuration on a point-to-point
interface or on a point-to-multipoint interface.
CÛ NOTE
• The FRF. 9 compression is applicable for low-speed links.
• The MFR link does not use the FRF. 9 compression function.
• The FRF. 9 compression involves a synchronization process. The compression is usually
unsuccessful if packets are not in order during the compression.
Preconfiguration tasks
Before configuring FR compression, complete the following tasks:
• Configuring physical parameters for FR interfaces
• Configuring
Data preparation
To configure FR compression, you need the following data.
No Data
1 FR interface number of a router and IP addresses to be allocated
2 VC number of local interfaces
Configuration procedures
No. Procedure
1 Configuring FRF.9 compression on a point-to-point sub-interface
2 Configuring FR FRF.9 compression on a main-interface or a point-to-multipoint
sub-interface
3 Checking the configuration
CQ NOTE
FR FRF. 9 compression can take effect only after it is configured on the devices on both ends.
