Prerequisites:
 Cisco Image        (c7200-a3jk9s-mz.124-25g.image)

If you do not have this image then just use any image you possess which supports frame-relay and serial interfaces.
Create topology as shown in this lab and then proceed to configure routers.


Introduction:
This lab teaches CCNA students how to configure frame-relay switch out of the router, using connect command.


Topology:


Scenario:
Two routers in the middle of the topology are frame-relay switches connected to the clients, you need to create a bidirectional path across frame-relay cloud between two interfaces facing customer locations. DLCI 100 will be used for client sites and DLCI 50 on the link between frame-relay switches as shown in the topology.

Lab procedure:

Step1: Configure customer sites.

R4(config)#
interface Serial1/0
 ip address 10.0.0.1 255.255.255.252
 encapsulation frame-relay
 frame-relay intf-type dte
 frame-relay map ip 10.0.0.2 100 broadcast
 no shutdown

R5(config)#
interface Serial1/0
 ip address 10.0.0.2 255.255.255.252
 encapsulation frame-relay
 frame-relay intf-type dte
 frame-relay map ip 10.0.0.1 100 broadcast
 no shutdown

Step2: Enable frame-relay switching.

FRSW1(config)# frame-relay switching
!
FRSW2(config)# frame-relay switching

Step3: Configure the link between frame-relay switches.

FRSW1(config)#
interface Serial1/0
 encapsulation frame-relay
 clock rate 8064000
 frame-relay intf-type nni
 no shutdown

FRSW2(config)#
interface Serial1/0
 encapsulation frame-relay
 clock rate 8064000
 frame-relay intf-type nni
 no shutdown


Step4: Configure interface facing customer's routers.

FRSW1(config)#
interface Serial1/1
 encapsulation frame-relay
 clock rate 8064000
 frame-relay intf-type dce
 no shutdown

FRSW2(config)#
interface Serial1/1
 encapsulation frame-relay
 clock rate 8064000
 frame-relay intf-type dce
 no shutdown


Step5: Using connect command in global configuration mode you create bidirectional path just with one statement.

FRSW1(config)#connect R4_TO_R5 serial 1/1 100 serial 1/0 50
!
Repeat this process on the second switch:
!
FRSW2(config)#connect R4_TO_R5 serial 1/1 100 serial 1/0 50



Step6: Verify connections map.

FRSW1#show connection all

ID   Name               Segment 1            Segment 2           State     
========================================================================
1    R4_TO_R5          Se1/1 100            Se1/0 50             UP

FRSW2#show  connection all

ID   Name               Segment 1            Segment 2           State     
========================================================================
1    R4_TO_R5          Se1/1 100            Se1/0 50             UP


Step7: Verify frame-relay configurations on the client sites:

R4#show frame-relay map
Serial1/0 (up): ip 10.0.0.2 dlci 100(0x64,0x1840), static,
              broadcast,
              CISCO, status defined, active

R4#ping 10.0.0.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/40/48 ms
