This field indicates how DC-BGP handles a tie when determining the preferred route between two routes of essentially equal cost received from BGP peers external to the local AS or confederation. If this is FALSE then DC-BGP uses the standard algorithm tie-breaker, comparing the peer BGP router ID, cluster list length and peer IP address as tie breakers. This is the default behavior and is required for DC-BGP to use the decision process as defined in the BGP standards. If this is TRUE then DC-BGP always chooses a route that is currently selected as the best path to break the tie. If there is no current best path, or for routes received from BGP peers internal to the local AS or confederation, DC-BGP continues to use the standard algorithm. All BGP routers in an AS should have the same configuration for this field to avoid routing loops. This field can only be changed when the Admin Status is down.
