Apparently you can use 2 DLCI's back to back without a Frame Switch. Umit
posted these configs earlier (Thanks Umit!). Each DLCI provides a one-way
communication path between the routers. All traffic from the DTE side
heading to 10.0.0.2 takes DLCI 101 while all traffic from the DCE side takes
DLCI 102.
>>------------------->>>DLCI 101>>>------------------>>
DTE
DCE
<<-------------------<<<DLCI 102<<<------------------<<
DTE Side:
Interface s0
encap frame-relay
ip add 10.0.0.1 255.255.255.0
frame-Relay map ip 10.0.0.2 101 broadcast
no keepalive
frame-relay interface-dlci 102
DCE Side:
Ineterface s0
encap frame-relay
ip add 10.0.0.2 255.255.255.0
Frame-Relay map ip 10.0.0.1 102 broadcast
clock rate 128000
no keepalive
frame-relay interface-dlci 101
