单选题Which statement about MPLS traffic engineering policy-based tunnel selection （PBTS） is not true？（）A The tunnel that is not configured with the policy-class command acts as the defaultB EXP selection is between multiple tunnels to the same destinationC
题目
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
