Re: MPLS TE RSVP bandwidth delim

Dont think an RSVP tunnel as a CAT6 cable, it is a bad assumption
I see the problem you concer of getting an 4mega reservetion on a P router and since it is a dynamic tunnel and if you have fancy topology you could Be using 4megas on a P router
You cant cut a cat6 in a half :)
You are trying to guarantee 2megas, your question do not say how much you can allocate on the backbone side so you could config UNI or BI
And police on the edge so the CE do burst upto 2mega

Q1
We always try to keep everything simetrical, so we do BI
Q2
They are always UNI
