When set to TRUE DC-BGP insists upon strict adherence by peers to the protocol specification, rejecting AS-Path attributes with erroneous AS-Confed segments. When set to FALSE DC-BGP adopts a more pragmatic approach dealing as best it can with non standard AS-Path information. This latter approach can be useful in allowing interoperability with older, non-standards compliant peers. To be specific, the following rules are NOT applied to incoming BGP UPDATEs when this field is FALSE. - Confederation AS Path information is not permitted if either the local BGP router is not in a confederation, or if the BGP peer is not in the local BGP router's confederation. - If the BGP peer is in the local BGP router's confederation then the AS Path must contain confederation segments, and the first AS Path segment must be of type AS_CONFED_SEQUENCE. This field can only be changed when the Admin Status is down.
