Abstract Abstract
For operational simplification of "sessionless" applications using For operational simplification of "sessionless" applications using
BFD, in this document we present procedures for "unsolicited BFD" BFD, in this document we present procedures for "unsolicited BFD"
that allow a BFD session to be initiated by only one side, and be that allow a BFD session to be initiated by only one side, and be
established without explicit per-session configuration or established without explicit per-session configuration or
registration by the other side (subject to certain per-interface or registration by the other side (subject to certain per-interface or
per-router policies). per-router policies).
