The document describes the configuration of a multipoint Frame Relay network using Cisco routers and a Frame Relay switch. DLCI to port mappings are configured on the Frame Relay switch to connect the routers. Each router is configured with Frame Relay encapsulation and DLCI mappings to connect to the other routers over the Frame Relay network. The connectivity between routers is tested using ping commands.

1. FRAME RELAY (MULTIPOINT)
WWW.NETPROTOCOLXPERT.IN

2. • HERE, IN MULTIPOINT FRAME-RELAY CONFIGURATION, WE WILL USE THE SAME
CISCO ROUTERS AND A FRAME RELAY SWITCH. BUT HERE, OUR CONFIGURATION
WILL NOT BE POINT-TO-POINT ONLY. ROUTERS WILL BE CONNECTING TO THE
ROUTERS AS MULTIPOINT.
• WE WILL START WITH FRAME-RELAY SWITCH AGAIN. CREATE A FRAME-RELAY
SWITCH AND RIGHT CLICK THE FRAME-RELAY SWITCH. INJECT THE DLCI – PORT
MAPPING LIKE BELOW:

8. AFTER ALL THE CONFIGURATIONS DONE, YOU CAN CHECK THE
CONNECTION BETWEEN ROUTERS WITH THE BELOW PING
COMMANDS. AND YOU ALSO CHECK THE FRAME-RELAY PVC ON
ROUTERS.
