3. Set up the interfaces on the router.
Frswitch(config)#int s0/0
Frswitch(config-if)#enc frame-relay
Frswitch(config-if)#frame-relay intf-type dce
Frswitch(config-if)#clockrate 56000
Frswitch(config-if)#no shut
Frswitch(config)#int s0/1
Frswitch(config-if)#enc frame-relay
Frswitch(config-if)#frame-relay intf-type dce
Frswitch(config-if)#clockrate 56000
Frswitch(config-if)#no shut
4. Then configure a dlci-switching table on EACH interface.
Frswitch(config)#int s0/0
Frswitch(config-if)#frame-relay route 18 interface s0/1 16
Frswitch(config)#int s0/1
Frswitch(config-if)# frame-relay route 16 interface s0/0 18
5. You are now ready to start using your frame–relay switch. Don’t forget to
save the configuration.
Supplemental Lab or Challenge Activities:
1. Go out and research how many serial lines can be put into a 2610, 2611, 2620,
or 2620 router. Why are we limited to just 2 serial lines or can we have more?
Surely we might need more than two routers hooked together with frame
relay. For example:
Seattle
S0/3 Detroit
(dlci#19) s0/2
(dlci#17 )
s0/0 (dlci#16) s0/1 (dlci#18)
Los Angeles
Tampa
So what have I learned here?
In this lab you learned how to turn a router into a frame relay switch. Would you do this
inside a company? Almost always no. Your serial lines with HDLC can provide
clocking to move the information. In the next couple of labs you will learn about
configuring different topologies with frame relay networking.
