Configuring FRF.5 and FRF.8 Internetworking Functions

To communicate over WANs, end-user stations and the network cloud typically must use the same type

of transmission protocol. This limitation has prevented differing networks such as Frame Relay and ATM

from being linked. The Frame Relay–to–ATM Service Interworking feature allows Frame Relay and

ATM networks to exchange data despite differing network protocols. The functional requirements for

linking Frame Relay and ATM networks are provided by the Frame Relay/ATM PVC Service

Interworking Implementation Agreement specified in Frame Relay Forum (FRF) documents FRF.5 and

FRF.8. The FRF.5 and FRF.8 interworking functions involve multiplexing PVCs between Frame Relay

and ATM networks and mapping the control bits between Frame Relay frame headers and ATM cell

headers. FRF.5 and FRF.8 are necessary for ATM-based features to interwork with Frame Relay–based

IP class of service (CoS) features.

Configuration Examples

These examples show how to configure a mapping between a Frame Relay data-link connection

identifier (DLCI) and an ATM PVC, using the connect command. For a full description of the connect

command as used in the FRF.5 and FRF.8 internetworking functions, refer to Enhanced Voice and QoS

for ADSL and G.SHDSL on Cisco 1700 Series, Cisco 2600 Series, and Cisco 3600 Series Routers.

For FRF.5 and FRF.8, you may need to match the maximum transmission unit (MTU) between the ATM

Note

and Frame Relay networks for large size packets.

FRF.5

The following example shows how to create an FRF.5 connection, using the network-interworking

keyword in the connect command.
