Setting the bandwidth statement on the interface will effect the metric.
Normally a backup pvc will have a lower CIR then the primary PVC so on the
sub-interfaces if you set the bandwidth to match the CIR it will be used in
the metric calcuation. It also help NMS systems when they are monitoring a
WAN link for load.
