Frame Relay Switch Install

Frame-Relay Switch Install

Configuration of frame relay switch on cisco router  for labs is fairly straight forward

I am using a cisco 2610 with serial 8 a/s card. I have my dce of my serial cables
connected to the cisco 2610 fr switch and the dte connected to the relevant routers
The first thing that needs to be done in global config mode on the fr switch is to
enable frame-relay switching
router(config)#frame-relay switching
then you go to your relevant serial interface depending on the device you are
connecting so I am doing router 6 which connects to s1/4 on my frame relay switch
this is going to communicate to router 5 on interface serial 1/5
int s1/4
encap frame-relay
clock rate 56000
frame-relay intf-type dce
no frame inverse
frame-relay route 122 interface serial 1/5 221

int s1/5
encap frame-relay
clock rate 56000
frame-relay intf-type dce
no frame inverse
frame-relay route 221 interface serial 1/4 122

As your dce you need to put clocking
The frame-relay route command breaks down as follow
frame-relay route 221 (r6 dlci) interface serial 1/4 (interface to outgoing dlci so r5
connected interface) 221 ( r5 dlci)

For the ine config i have the following physical connections for the routers to the frame relay switch
                        
r3 s1/0 is connected to s1/6
r3 s1/1 is connected to s1/7
r2 s0/0 is connected to s1/2
r1 s0/0 is connected to s1/0
r4 s0/0 is connected to s1/3
r5 s0/0 is connected to s1/5
r6 s0/0 is connected to s1/4
The config for the switch is below in full
