    abstract =  {This document describes extensions to the Label Distribution Protocol (LDP) to signal a switching preference in the presence of multiple paths. A label switched router (LSR) can associate locally a color with one or more downstream paths or links, and signal a label path per color to upstream LSRs. Based on local policy, LSRs can select between these color LSPs to implement a forwarding preference on a downstream LSR. An egress LSR may influence the signaling decision of other LSRs by signaling interest in specific colors.},
