Destination Preference Attribute (DPA) This document proposes the DPA path attribute, which is an optional transitive attribute of fixed length. The attribute is represented by a pair . The AS# is a two octet non-negative integer, which denotes the AS that specifies the preference. The DPA value is a four octet non-negative integer. - The DPA attribute has Type Code 10. Code 10 is chosen so as not to - conflict with existing and other proposed codes. + The DPA attribute has Type Code 11. Route Selection Process The DPA attributes are considered comparable only if the DPA attributes are present in all the routes being compared and are set by the same AS. The comparable DPA attributes shall be used as a selection criteria, after the "local_pref" attribute is evaluated, and before the evaluation of the AS path length and the multi-exit-discriminator @@ -131,24 +130,23 @@ insightful comments and suggestions.
