Abstract
Various example embodiments for supporting multicast are presented. Various example embodiments for supporting multicast are configured to support multicast, on a multicast tree for a multicast group, based on use of penultimate hop popping (PHP) on the multicast tree. Various example embodiments for supporting multicast are configured to support multicast, on a multicast tree for a multicast group, based on use of PHP on the multicast tree where the multicast tree is Point-to-Multipoint (P2MP) Multiprotocol Label Switching (MPLS) tree that is formed based on a TREE-SID multicast solution (although it will be appreciated that PHP may be applied on other types of multicast trees (e.g., other than P2MP MPLS multicast trees), on multicast trees formed based on other multicast solutions (e.g., other than TREE-SID), or the like, as well as various combinations thereof).
