This technique works effectively as long as the VRF that exports the route is not on the same PE as the VRF(s) that import the route. However, due to the constraints of the BGP protocol, it does not work if the two are on the same PE. This document describes a modification to the BGP protocol allowing this technique to work when the VRFs are on the same PE, allowing the technique to be used in a standard manner throughout an autonomous system.}, }
