Item	Description
Local_Address	Local address.
Peer_Address	Peer address.
Multiplier	Remote detection multiplier.
Interface	Interface used to set up the BFD session. Information about the interface is displayed only when the EBGP peer relationship is set up between it and its directly connected interface; otherwise, the interface information is displayed as Unknown.
Session-State	BFD status: BFD global disable: BFD is globally disabled. Up: The BFD session is in the Up state. Down: The BFD session is in the Down state. Unknown: When BFD fails to go Up for the first time, whether the link is faulty is unknown.
Tx-interval(ms)	Interval at which BFD packets are sent, in milliseconds.
Rx-interval(ms)	Interval at which BFD packets are received, in milliseconds.
Wtr-interval(m)	WTR time of the BFD session, in minutes.
