    abstract =  {A Source Identifier (SI) is carried in an MPLS Source Label and used to identify (one of) the ingress LSR(s) to a specific LSP. This document defines extensions to OSPF protocol for distribution of the correlation of a SI to an specific LSR. Therefore, the egress and intermediate LSRs can determine from which LSR an MPLS packet is sent. This document also defines OSPF extensions to advertise the Source Label Capability (SLC) of each LSR that indicates whether an LSR can properly process the Source Label Indicator (SLI) special purpose label and Source Label (SL). With the SLC, an ingress LSR can determine whether it is allowed to insert a SL into the label stack for a specific LSP.},
