In case it hasn't occurred to others, I'll add that even without a cable the fr
ame switch can participate (at layer 3) in a frame cloud that it's providing.
Below is a sample config that enables a 2 ser port router to provide a frame cl
oud for three routers (including itself). In this case, the frame switch is pa
rticipating as a "spoke" router through subinterface s0.1. The "hub" router is
attached to serial 0 and has frame maps to dlci's 102 and 103.

Sure can, you can save on routers this way. Post your config so we can
troubleshoot your problem.

Subject: The same box as a FR switch and FR DTE????
Is it possible to have two interfaces on the same box connected back-to-back
(one int configured as FR DCE and the other interface configured as FR DTE)
and then create a PVC between the int configured as DTE and another router
which as an int configured as DTE??
I have never tried this one before..
Details -
Objective: To create a PVC between R3 and R6. (But R6 is also the Frame
switch)
So I have made the following connections:
S0(R6) - S4(R6)
S1(R6) - S0(R3)
Trying to configure the PVC between S4(R6) and S0(R3)
I have configured the S0 and S1 interfaces of R6 as FR DCE and S4 of R6 as
FR DTE.
The PVC does NOT come up....
On router R3( I am using a subif on R3), it says...
R3#sh frame pvc int s0.1
PVC Statistics for interface Serial0.1 (Frame Relay DTE)
DLCI = 306, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE = Serial0.1
input pkts 0 output pkts 3 in bytes 0
out bytes 915 dropped pkts 0 in FECN pkts 0
in BECN pkts 0 out FECN pkts 0 out BECN pkts 0
in DE pkts 0 out DE pkts 0
out bcast pkts 3 out bcast bytes 915

R3#sh frame map
