attribute. This behaviour is not mandated or suggested
by RFC5065.

When set to TRUE, in scenario described above the BGP
AS_PATH attribute must be considered a valid path attribute.
This behaviour is fully compliant with RFC5065.
If an implementation supports peer-ASN (leftmost) validation
in AS_PATH against peer-ASN negotiated in OPEN message,
the loose-path-validation set to TRUE does not relax this
validation.";
