Question 33 0 / 1 point

Is the following statement TRUE or FALSE: The length of the AS path is extended because additional copies of the AS number of the sender are prepended to the original AS path attribute. To avoid clashes with BGP loop prevention mechanisms, no other AS number, except that of the neighboring AS, should be prepended to the AS path attribute.
