hi Friends,
I have doubt in the task 7.1. Task states
The Frame Relay interfaces of R3, R4, and R5 all physically support a speed
of T1, however the Frame Relay circuits are not provisioned in this way. The
circuit between R3 and R5 is provisioned at 512Kbps while the circuit
between R4 and R5 is provisioned at 1024Kbps.
Configure FRTS so that all end points of the network conform to the
provisioned rate.
Both spokes should be allowed to burst up to their access-rate if they
have accumulated credit.
Scenario is like this
R5----------FR Cloud------------R3--------------------FR Cloud
--------------R4
R3 is the hud and both R4 R5 are spokes.
I have used the config
*ON R3*
map-class frame-relay DLCI304
frame-relay cir 1024000
frame-relay bc 128000
!
map-class frame-relay DLCI305
frame-relay cir 512000
frame-relay be 64000
!
*ON R4*
map-class frame-relay DLCI403
frame-relay cir 1024000
frame-relay bc 128000
frame-relay be 64000
*ON R5*
map-class frame-relay DLCI503
frame-relay cir 512000
frame-relay bc 64000
frame-relay be 128000
*But the solution used the values*
*R3:*
map-class frame-relay DLCI_304
frame-relay cir 1024000
frame-relay bc 10240
!
map-class frame-relay DLCI_305
frame-relay cir 512000
frame-relay bc 5120
*
R4:
*
map-class frame-relay DLCI_403
frame-relay cir 1024000
frame-relay bc 10240
frame-relay be 5120
*
R5:
*
map-class frame-relay DLCI_503
frame-relay cir 512000
frame-relay bc 5120
frame-relay be 10240
*I know the values came when Tc is taken to be 10ms but that was never
mentioned in the task. Please help me as this is again confusng me a lot. if
nothing is specified we use default value for Tc which is 125ms but here
they have used 10 ms.*
Any prompt reply is most welcome . As my lab is approching very soon.
Thanks and Regards
Anshuk
