Abstract
Various example embodiments relate generally to supporting Multiprotocol Label Switching (MPLS)-based multicast over a Bit Index Explicit Replication (BIER) domain. Various example embodiments for supporting MPLS-based multicast over a BIER domain may be configured to support MPLS point-to-multipoint (P2MP) label switched paths (LSPs) over a BIER domain. Various example embodiments for supporting MPLS-based multicast over a BIER domain may be configured to support establishment and transport of P2MP LSPs over a BIER domain (e.g., signaling MPLS via the BIER domain, stitching the MPLS datapath to the BIER domain based on identification of P2MP LSPs within the BIER domain, and so forth).
Claims28
1-27. (canceled)
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least:
- receive, by a Bit Index Explicit Replication (BIER) border router (BBR) of a BIER domain from a Multiprotocol Label Switching (MPLS) domain, MPLS signaling information associated with a point-to-multipoint (P2MP) label switched path (LSP);
- and
- send, by the BBR toward a device configured to assign a BIER tree label (BTL) identifying the P2MP LSP within the BIER domain, the MPLS signaling information associated with the P2MP LSP.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least:
- receive, by a device associated with a Bit Index Explicit Replication (BIER) domain, Multiprotocol Label Switching (MPLS) signaling information associated with a point-to-multipoint (P2MP) label switched path (LSP);
- and
- assign, by the device based on the MPLS signaling information associated with the P2MP LSP, a BIER tree label (BTL) identifying the P2MP LSP within the BIER domain.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least:
- obtain, by a Bit Index Explicit Replication (BIER) border router (BBR) of a BIER domain, a BIER tree label (BTL) identifying a point-to-multipoint (P2MP) label switched path (LSP) within the BIER domain.
