The second option explained by you will not allow to
input the frame-relay intf dce command with
frame-relay switching global command.
Also with the first option you can also configure the
frame-switch switching on a interface with a DTE cable
connected to it. all the commands except the clock
rate will be there.
the clock rate command will then go and sit on the
router connect to the particular frame switch
interface.
here is the config (2nd option)for the back-to-back
frame-relay without a actual frame-switch in between.
this is the second option
R1(s0-dce) ------------(s1-dte) R2
router r1
int s0
clock rate 64000
encap frame
ip address 1.1.1.1 255.255.255.0
frame-relay map ip 1.1.1.2 102 broadcast
no keepalive
no shut
router r2
int s1
ip addres 1.1.1.2 255.255.255.0
encap fram
frame-relay map ip 1.1.1.1 102 broadcast
no keepalive
no shut
with the above configs, you don't need frame-relay
switching command at all and also if you notice the
DLCI's are same on both sides !!
this is tried and tested method..
hope that helps
