First of all, your frame switch interfaces need the frame-relay
interface-type DCE configured
Secondly, from your edge routers, what does show frame-relay pvc yield?
The clock rate command should be configured on the router where the DCE end
of the serial cable is attached. This can be different than the interface
where the frame-relay interface-type is configured.
Try these things first then report back.

Subject: frame relay on lab8 ccbootcamp
Having problems with lab 8. Basically I can bring up
the two routers connected via point-to-point frame
relay. However, I can not bring up the multipoint
connection from r5 to r2 and r3. Can anyone spot the
issues or at least explain what a looped serial
interface could imply? Here are my interfaces on the
fr switch:
interface Serial0 (goes to r2)
no ip address
no ip directed-broadcast
encapsulation frame-relay
no ip mroute-cache
no keepalive
no fair-queue
frame-relay route 105 interface Serial2 501
interface Serial3 (goes to r3)
no ip address
no ip directed-broadcast
encapsulation frame-relay
keepalive 20
cdp enable
frame-relay lmi-type ansi
frame-relay route 305 interface Serial2 503
R3 serial int s1
interface Serial1
ip address 137.20.100.35 255.255.255.224
encapsulation frame-relay
ip ospf network point-to-multipoint
clockrate 64000
cdp enable
frame-relay map ip 137.20.100.34 305 broadcast
frame-relay lmi-type ansi
****** shows as up, down (looped)
R2 int s0
interface Serial0
ip address 137.20.100.33 255.255.255.224
encapsulation frame-relay
no fair-queue
clockrate 64000
frame-relay map ip 137.20.100.34 105 broadcast
frame-relay lmi-type ansi
***** shows in show int as up, down*******
R5 subinterfaces
interface Serial1
no ip address
encapsulation frame-relay
bandwidth 2000
keepalive 15
no fair-queue
frame-relay lmi-type ansi
!
interface Serial1.1 multipoint
ip address 137.20.100.34 255.255.255.224
frame-relay map ip 137.20.100.33 501 broadcast
frame-relay map ip 137.20.100.35 503 broadcast
!
interface Serial1.2 point-to-point
ip address 137.20.200.17 255.255.255.240
frame-relay interface-dlci 504
!
***** again point-to-point works fine, but not multi***
