I know that frame-relay is seeing his last days, but since some students asked for it here is as sample configuration of the generic cloud-pt as a frame-relay switch.
1º Step – Add a Generic Cloud to the Packet Tracer Topology
2º Step – Add 3 router C2911
3º Step – Add HWIC-2T modules to the routers to provide the serial interfaces needed for the frame-relay connections
4º Step – Connect the serial interface 0/0/0 from each router to the cloud using a DTE Serial Cable. (it is important to connect from the router to the cloud and not the other way around)
5º Step – Address used in the example:
- IP Addresses
- R1-R2 – 10.0.0.0/30
- R1-R3 – 10.0.0.4/30
- Data Link Connection Identifier (DLCI)
- R1-R2 – 102
- R1-R3 – 103
- R2-R1 – 201
- R3-R1 – 301
6º Step – Configure the Frame-Relay Cloud with the DLCI per Interface
7º Step – Configure the Frame-Relay routes between the interfaces
8º Step – We will had interface loopback in the configuration to simulate the local lans
9º Step – Configurations
