Basic Multipoint Frame Relay Configuration

Basic Multipoint Frame Relay Configuration

Here, in multipoint Frame-Relay configuration, we will use the same Cisco 3600 series 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. Adjuct the DLCI – port mapping like below:

1:102 10:201
1:103 11:301
1:104 12:401

After mapping, connect the routers to the Frame-Relay Switch port mentioned in the mapping via serial connection. ( R1 to port 1, R2 to port 10, R3 to port 11, R4 to port 12)

It is time to configure our routers. The Hub Router is R1 again. Make the below configurations on all routers.

R1 Configuration

R1(config)# no logging console
R1 (config)# int s 0/0
R1 (config-if)# no shut
R1 (config-if)# encapsulation frame-relay
R1 (config-if)# ip address
R1 (config-if)# frame-relay map ip 102 broadcast
R1 (config-if)# frame-relay map ip 103 broadcast
R1 (config-if)# frame-relay map ip 104 broadcast
R1 (config-if)# end
R1 # write

R2 Configuration

R2 (config)# no logging console
R2 (config)# int s 0/0
R2 (config-if)# no shut
R2 (config-if)# encapsulation frame-relay
R2 (config-if)# ip address
R2 (config-if)# frame-relay map ip 201 broadcast
R2 (config-if)# frame-relay map ip 201 broadcast
R2 (config-if)# frame-relay map ip 201 broadcast
R2 (config-if)# end
R2 # write

R3 Configuration
