Abstract Abstract
This document describes how to leverage Segment Routing (SR) to This document describes how to leverage Segment Routing (SR) to
ensure that the Unaffiliated BFD (U-BFD) Echo packets must reach the ensure that the Unaffiliated BFD (U-BFD) Echo packets must reach the
remote system before being looped back to the local system. This remote system before being looped back to the local system. This
enables that U-BFD works not only for one hop scenario but for enables that U-BFD works not only for one hop scenario but for
multiple hops scenario as well. multiple hops scenario as well.
In addition, this document also defines a way to explicitly specify In addition, this document also defines a way to explicitly specify
