out_if_name -		Specifies the type and number of the interface bound to the BFD session.
remote_discr - added in 2.9		The BFD session remote identifier does not need to be configured when the mode is auto.
session_name - / required		Specifies the name of a BFD session. The value is a string of 1 to 15 case-sensitive characters without spaces.
