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 192.168.10.1 255.255.255.0
R1 (config-if)# frame-relay map ip 192.168.10.2 102 broadcast
R1 (config-if)# frame-relay map ip 192.168.10.3 103 broadcast
R1 (config-if)# frame-relay map ip 192.168.10.4 104 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 192.168.10.2 255.255.255.0
R2 (config-if)# frame-relay map ip 192.168.10.1 201 broadcast
R2 (config-if)# frame-relay map ip 192.168.10.3 201 broadcast
R2 (config-if)# frame-relay map ip 192.168.10.4 201 broadcast
R2 (config-if)# end
R2 # write

R3 Configuration

R3 (config)# no logging console
R3 (config)# int s 0/0
R3 (config-if)# no shut
R3 (config-if)# encapsulation frame-relay
R3 (config-if)# ip address 192.168.10.3 255.255.255.0
R3 (config-if)# frame-relay map ip 192.168.10.1 301 broadcast
R3 (config-if)# frame-relay map ip 192.168.10.2 301 broadcast
R3 (config-if)# frame-relay map ip 192.168.10.4 301 broadcast
R3 (config-if)# end
R3 # write

R4 Configuration

R4 (config)# no logging console
R4 (config)# int s 0/0
R4 (config-if)# no shut
R4 (config-if)# encapsulation frame-relay
R4 (config-if)# ip address 192.168.10.4 255.255.255.0
R4 (config-if)# frame-relay map ip 192.168.10.1 401 broadcast
R4 (config-if)# frame-relay map ip 192.168.10.2 401 broadcast
R4 (config-if)# frame-relay map ip 192.168.10.3 401 broadcast
R4 (config-if)# end
R4 # write

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.

R1 # show frame-relay pvc
R1 # ping 192.168.10.2
R1 # ping 192.168.10.3
R1 # ping 192.168.10.4

R2 # show frame-relay pvc
R2 # ping 192.168.10.1
R2 # ping 192.168.10.3
R2 # ping 192.168.10.4

R3 # show frame-relay pvc
R3 # ping 192.168.10.1
R3 # ping 192.168.10.2
R3 # ping 192.168.10.4

R4 # show frame-relay pvc
R4 # ping 192.168.10.1
R4 # ping 192.168.10.2
R4 # ping 192.168.10.3

hi
ok i finally found a config that is done the way i did mine but i did it withi three routers and a cisco switch using static maping , the problem is when i add loopbacks on routers and used eigrp no routes are shown in the routing table and i cnt ping loopbacks ,i have seen many examples where they do it with subinterfaces but y cnt we do it withoug subinerfaces , hope if sm1 cn help
