Which statement about MPLS traffic engineering policy-based tunnel selection （PBTS） is not true？（）

The tunnel that is not configured with the policy-class command acts as the default

EXP selection is between multiple tunnels to the same destination

There is no requirement for IGP extensions

Tunnels are configured using the policy-class command and carry multiple EXP values

It supports VRF traffic， IP-to-MPLS switching， and MPLS-to-MPLS switching
