Thanks for your replies. But question doesn't say anything about CIR.
R1 and R2 are connected through their frame-relay P2P subinterfaces
together. There is no other DLCI on each router. R1 (only 102) , R (only
201).
Question : " PVC 102/201 should be configured with MINCIR 64000 bps and Peak
Rate 64000 bps. Use the technique based on dual token bucket algorithm to
mark outgoing traffic on R1 and R2 with the discard eligible bit, if the
traffic exceeds 1000 byte normal burst size and 1000 byte excess burst size
at the committed rate of 32000 bps"
I read the question about 5 times, but I'm still confused. MinCir=64000 and
PeakRate 64000? How about cir?
Maybe we must understood when the MinCir=PeakRate then the cir also must be
equal to them.
In solution, they used this command:
frame-relay mincir 64000
frame-relay traffic-rate 64000 64000
!
With " frame-relay traffic-rate" command IOS sets the cir, bc, be
automatically.
I'll appreciated if someone could explain about the answer.
The Answer is :
map-class frame-relay pvcR1-R2
frame-relay mincir 64000
frame-relay traffic-rate 64000 64000
service-policy output setde

policy-map setde

Hi Reza,
MIN CIR cannot be less than CIR, maybe it is 12800???
CIR =64000
be=1000
bc=1000
shape on peak =128000

Hi Reza,
is called two rate policer or two colors policing. Because you are
playing with CIR and PIR. We used to configure everything with CIR in
mind only, but there's a tons of fun outhere... ;)
Br,
