4.2 Configuring for PASSTHRU over Frame Relay
To set up a PASSTHRUOFR application you need to configure:
On the source unit (Unit 1 in Figure 4-1):
• A connection to the Frame Relay network, using a FR-USER port
• A PASSTHRUOFR port set to receive user traffic (from radar equipment, in this
example) and packetize it in cells
• A TRANSP PVC set to transport the PASSTHRUOFR traffic over the Frame
Relay multicast PVC defined in the Frame Relay switch/network.
On each destination unit (Units 2 and 3 in Figure 4-1)
• A FR-USER port facing the Frame Relay network
• A TRANSP PVC set to receive the PASSTHRUOFR traffic that is multicast by
the Frame Relay network
• A PASSTHRUOFR port set to transmit the traffic received from the remote radar
equipment back to the attached user equipment (monitors, in this example).
The required commands for complete application configuration are shown in Figure 4-2.
