BFD offers a low-resource method for constant pseudowire data path monitoring and data plane failure detection. It supports asynchronous BFD for VCCV, as per RFC 5885. While ping operations can also detect failures, BFD uses fewer resources and is faster. BFD for pseudowires is compatible with LDP-based Layer 2 circuits, BGP-based Layer 2 VPNs, and LDP-based or BGP-based VPLS.

  • Efficient Data Path Monitoring: BFD offers a low-resource method for continuous pseudowire data path monitoring and data plane failure detection
  • Asynchronous BFD Support: This feature enables asynchronous mode BFD for VCCV, as outlined in RFC 5885
  • BFD for Pseudowires: Supported for Layer 2 circuits (LDP-based), Layer 2 VPNs (BGP-based), and VPLS (LDP-based or BGP-based)
  • Distributed BFD Model: Junos OS employs a distributed model for BFD for VCCV
  • Periodic Packet Management: The ppmd process on PIC concentrators handles periodic packet management (send and receive) for BFD for VCCV
