Abstract
The Border Gateway Protocol [1] is an inter-autonomous system routing protocol designed for TCP/IP internets. This document describes a new BGP path attribute termed 'Destination Preference Attribute' (DPA) which can be used by a single autonomous system (AS) to specify globally transitive metrics in its routing announcement via BGP. The metric can then be used by upstream BGP speakers to favor certain path for return traffic. The application of this attribute includes facilitating the implementation of symmetric routing and load sharing in the multi-provider Internet.
