Abstract:
A method of using a point-to-point (P2P) label switched path (LSP) to transmit multicast data packets partially through a multiprotocol label switched (MPLS) network when one or more label switched routers (LSRs) of the MPLS are not multicast label distribution protocol (mLDP) enabled. The P2P LSP can be used to transmit multicast data packets to the head end of a point-to-multipoint (P2MP) LSP created with mLDP enabled LSRs. The P2MP LSP can be used to transmit the multicast data packets through the MPLS network to intended receivers that are external to the MPLS network. The P2MP LSP can be built from an egress edge LSR towards an ingress edge LSR, by mLDP enabled LSRs. The P2P LSP can be built from a core mLDP enabled LSR to the ingress edge LSR, across a non-mLDP enabled LSR between the core mLDP enabled LSR and the ingress edge LSR.
