The value of vRtrMplsIfTeMetric specifies the traffic engineering metric
for this interface. The TE metric is exchanged in addition to the IGP
metric by the IGPs. Depending on the value configured for
vRtrMplsLspCspfTeMetricEnabled, either the TE metric or the native
IGP metric is used in CSPF computations of the LSP paths. The maximum
value that can be configured is a 24 bit value.
