Struct BFD

layers/bfd.go:262–281

BFD represents a BFD control message packet whose payload contains the control information required to for a BFD session. References ---------- Wikipedia's BFD entry: https://en.wikipedia.org/wiki/Bidirectional_Forwarding_Detection This is the best place to get an overview of BFD. RFC 5880 "Bidir

//     Describes the use of the Bidirectional Forwarding Detection (BFD)
//     protocol over IPv4 and IPv6 for single IP hops.
type BFD struct {

// Length returns the data length of a BFD Control message which
// changes based on the presence and type of authentication
