Hi Team,

I had a query regarding the question 8. (section QOS ) in IEWB lab 16.

I didnt understand the values given in the solution guide.

R3 is the hub and R4 and R5 are the spokes R3 has a E1 capacity and the
requirement says that we should use the half of that for each circuit
between the spokes, with fram relay traffic shaping and we should burst upto
75% of the access rate if there is accumulated credit using default TC fo
rthe CIR.

so with that on the spokes..the configuration looks llike below on each of
the spokes:

map-class frame-relay CIR
frame-relay cir 1024000
frame-relay bc 64512
frame-relay be 32256

Now the question is the default TC is 125 ms which gives a BC of 128000

but the solution looks different: your all inputs would be valuable.

Thanks in advance,

Swaroop.
