Hi..Everyone..
I was confused by FRTS's Question..
I don't know the means of "Burst".
Is this a peak rate, bc or be ??
Who knows the correct answer help me..!!
Thanks..
---------
Diagram
---------
- R1's S0, R2's S0 & R3's S0.1 multipoint are coverd with a frame-relay
network
- R1's S0, R2's S0 & R3's S0.1 multipoint are in the same subnet,1.1.1.0/24
- R3 is a HUB , R1 & R2 are Spokes.
- The ip add od R1's S0 is 1.1.1.1/24
- The ip add od R2's S0 is 1.1.1.2/24
- The ip add od R3's S0.1 is 1.1.1.3/24
- The bandwidth of R1's S0 & R2's S0 is 64Kbps
- The bandwidth of R3's S0(Main-interface) is also 64 Kbps
--------
Question
--------
-If 2 remote frame-relay routers(R1 & R2) sent data back to the HUB(R3)
at same time, There is a congestion on R3.
=> "Do not allow bursting over the CIR " !!! *****
(what the mean of this Question ????)
---------
My answer
----------
interface Serial0
bandwidth 64 **
no ip address
encapsulation frame-relay
no fair-queue
frame-relay traffic-shaping **
frame-relay class FRTS **
no frame-relay inverse-arp
frame-relay lmi-type ansi
!
interface Serial0.1 multipoint
ip address 1.1.1.3 255.255.255.0
frame-relay map ip 1.1.1.2 603 broadcast
frame-relay map ip 1.1.1.1 605 broadcast
!
map-class frame-relay FRTS
frame-relay traffic-rate 64000 64000 **
=>I thought that CIR is 64000.
=>If The peak-rate equlas to CIR, it would not allow bursting over
the CIR **> is it right ??
How can i fix this problom????
