The packets are forwarded to the appropriate fabric queue according to the traffic
class/color combination. On a transit router, when the packet is forwarded out of
the tunnel, the router-generated output policy then sets the EXP bits back according
to the traffic class/color combination. Typically, the effect of the EXP bits to traffic
class/color combination to EXP bits is no change.
On an egress router, where the tunnel terminates, no router-generated output policy
is attached, and the packets pass out of the router subject to any manually configured
IP policy management applied to their traffic class/color combination.
