Feature Description

This feature enables MPLS support on UPF. VPC-SI uses VPP as the dataplane forwarder. VPP encapsulates and decapsulates subscriber traffic with MPLS labels.

UPF supports the following functionalities for MPLS support:

  • Uses the VPP MPLS stack to send the MPLS labeled packet

  • Uses the VPP MPLS stack to process the incoming labeled MPLS packet

  • MPLS on UPF uses only MP-BGP as the label distribution protocol

  • VPPCTL CLI commands to display FTN and ILM tables that are in VPP for debugging and comparing values with boxer configuration

For more information, refer to the MPLS Support on UPF chapter.
