RE: Burst Upto # FRTS

Carlos,

When dealing with policing, there are the extra calculations that must be done to take into account the bursting. So, you end up with 1.5 x target bc and 2 x target be values, which do not add up to AR, but over time still even out. However, I don't think the same rules apply for traffic shaping in Frame-Relay. FR questions that mention burst to a # (typically AR) are implying (bc+be)/tc to get there.

This is not always so simple, AFAIK.
Be is not Tc related, so there is no way to specify a 2 rate 3 colour
marker with just Bc & Be.
