Abstract

Bidirectional Forwarding Detection (BFD) for Virtual Circuit Connectivity Verification (VCCV) [RFC5885] defines the CV Types for BFD using VCCV, protocol operation, and the required packet encapsulation formats. This document extends those procedures and CV Type values to enable Seamless BFD (S-BFD) [RFC7880] operation for VCCV.

           Seamless Bidirectional Forwarding Detection (S-BFD)           for Virtual Circuit Connectivity Verification (VCCV)

Abstract

   This document defines Seamless BFD (S-BFD) for VCCV by extending the    procedures and Connectivity Verification (CV) types already defined    for Bidirectional Forwarding Detection (BFD) for Virtual Circuit    Connectivity Verification (VCCV).

   This document updates RFC 5885 by extending the CV Type values and    the capability selection.
