Re: MPLS TE RSVP bandwidth delim

Thanks Yuri,
Does that mean customer can pull 4 mb in total (2tx and 2rx).

How do we control this so customer only gets 2 MB. what is the best
practice?

One place that SP can control is on the SP edge using policing/shapping.
The potencial risk of this approach is when SP forgets policing/shaping.
Customer will enjoy 4 megs total bandwidth in this case.
