Hi yu,
Try the following
map-class frame-relay yu
frame-relay cir 64000
frame-relay bc 8000
frame-relay be 16000
frame-relay mincir 48000
The way cisco interprets these is as follows:
CIR is the access/physical rate in your case 64k
mincir is the committed information rate in your case 48K
Thus when dealing with cisco routes use the new terminology viz, CIR as the
physical rate and mincir as the term for CIR which telcos and you and me
know normally. I know it is confusing but that is the reality.
for explination of bc and be look at the following url, I have used bc as
1/8th of access rate and be double that of bc which is the default values
cisco routers use.
