Ok im only doing this on a simulator but I cannot get the two DTE routers to talk to each other: Here is the setup:

Lab_B is the frame-relay switch and has the following config:
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z
Router(config)#hostname lab_c
lab_c(config)#hostname lab_b
lab_b(config)#frame-relay switching
lab_b(config)#int s0/0
lab_b(config-if)#en
lab_b(config-if)#encapsulation frame-relay
lab_b(config-if)#int s0/1
lab_b(config-if)#encapsulation frame-relay
lab_b(config-if)#frame intf-type dce
lab_b(config-if)#frame-relay route 201 interface s0/0 102
lab_b(config-if)#clock rate 64000
lab_b(config-if)#int s0/0
lab_b(config-if)#frame intf-type dce
lab_b(config-if)#frame-relay route 102 interface serial0/1 201
lab_b(config-if)#clock rate 64000
lab_b(config-if)#
lab_b#write
Building configuration...
[OK]

i cannot ping lab_a from lab_C or the other way round... is there anything wrong with my commands?? Maybe its a simulation problem... not sure.
