[PlAwAnSaI]

When implementing Cisco MPLS TE, the constrained-based path calculations will use which value as the TE cost of each link within the MPLS domain?

B. It can only use the IGP metric as the TE cost.

C. Each link must be assigned a TE cost using the metric command.

D. It will use the interface bandwidth as the TE cost.
