This field indicates whether DC-BGP ignores AS path length when determining the preferred route from two BGP routes. If this is FALSE then DC-BGP treats the BGP route with the shorter AS path length as being the preferred route. 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 ignores the AS path length when determining the preferred route. Other attributes will be used to determine the preferred route. 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.
