In this unified MPLS we will found 3 types label.

INTER-AS MPLS option A

o one logical/physical interface per VRF in the interconnection

o one PE-CE eBGP/IGP session per VRF between ASBRs

o IP traffic between ASBRs

o no need for common RDs/RTs between ASNs

o 2 LSPs and 1 IP path from one PE to the other PE
