    The question:

    R6 to BB1 is only provisioned 25Mbps.

    Configure FR TS on R6 to avoid being dropped as it is sent out ..

    Use a shaping interval of 10 ms ...

    R6 should be allowed to send up to its access rate ..

     

    The solution given:

    map-class frame-relay TS
     frame-relay cir 25000000
     frame-relay bc 250000
     frame-relay be 200000
    !

    How do we get the exact calculation for this type of question? Is there a standard format?

     

    Thanks again.

    Re: [IEWB-SP-VOL2-V1-LAB2] 7.1 Traffic Limiting Hi there,

    Here you were given 10ms. However here are the formulas

    Bc = CIR * (Tc/1000)
    Be = (AR - CIR) * (Tc/1000)

    Thanks

    James
