Path selection metric for CSPF computation
The IGP floods two metrics for every link when the MPLS traffic engineering (TE) is configured in a network. The two metrics are the OSPF link metric and a TE link metric.
The interior gateway protocol (IGP) link metric for path calculation
- The traffic engineering (TE) link metric for path calculation
The IGP link metric is the default, but you can configure a TE-specific metric on an interface that is used instead for CSPF path computations.
