How to Configure Cisco Routers as Frame Relay Switch (FRS)?

Students and People who are preparing for the CCNA Exam often need to have a frame relay switch in their lab to practice for the Frame-Relay. How to configure Frame-Relay Switching on a Cisco Router? The following details and steps with topology diagram will explain the configuration.

In the following example we will take four routers R1, R2, R3 and R4 . The Router R2 will be working as the Frame relay Switch. Now open the GNS3 Simulator and create the following topology with the help of four Routers.

Configure Cisco Router as FRS-01

NOTE: Remember to create topology using only serial cables because Frame-Relay is a WAN technology and works only on wan links. Now open the console of Router R2 and start configuring it for Frame-Relay with the commands given below.

R2>enable

R2#configure terminal

R2(config)#frame-relay switching

R2(config)#interface s0/0

R2(config-if)#no shutdown

R2(config-if)#no ip address

R2(config-if)#clock rate 56000

R2(config-if)#encapsulation frame-relay

R2(config-if)#frame-relay intf-type dce

R2(config-if)#frame-relay route 103 interface s0/1 301

 

R2(config-if)#frame-relay route 104 interface s0/2 401
R2(config-if)#interface s0/1

R2(config-if)#no shutdown

R2(config-if)#no ip address

R2(config-if)#clock rate 56000

R2(config-if)#encapsulation frame-relay

R2(config-if)#frame-relay intf-type dce

R2(config-if)#frame-relay route 301 interface s0/0 103
R2(config-if)#interface s0/2

R2(config-if)#no shutdown

R2(config-if)#no ip address

R2(config-if)#clock rate 56000

R2(config-if)#encapsulation frame-relay

R2(config-if)#frame-relay intf-type dce

R2(config-if)#frame-relay route 401 interface s0/0 104
R2(config-if)#exit

To confirm your FRS is working properly you can use the following command :

R2#show frame-relay route
