Yo Adrian,
The formula to calculate bc is
BC = CIR * tc/1000
They tell you the tc in these types of questions, so that variable shouldn't
be a mystery...
That last bit of the question... FRF.12, or fragmentation... they are just
matching fragment size to the amount of data you can send in one tc. Just
remember the fragment size is entered in bytes (frame-relay fragment
command), where the tc is in bits and is not directly set, its actually set
by setting the bc!

Hi Group
The CIR part makes sense.But how did he get Bc?? and how is the last bit
where it says R1 and R3 should be able to trasmit a maximum of 3584 byres
shaping interval and R2 and R3 shud be able to transmit a maximum of 2560
bytes.
Is it that the last bit was used to calculate Bc ? if so how??
thks
