Thanks David. One clarification about your earlier email.
I am thinking of deploying this on my core facing interfaces. Basically on the interfaces where I have LDP/TDP enabled. So my question now is, will these interfaces be able to understand or see any DSCP markings in MPLS packets ? Will a match on DSCP markings work for MPLS packets on LDP/TDP enabled interfaces ?
