FIELD: physics.
SUBSTANCE: invention relates to packet forwarding. To this end, a method of an intermediate multiprotocol label switching unit (MPLS) for multicast communication includes the following: Service Provider (IP) node captures an MPLS packet in accordance with an access control list (ACL) rule, redirects a captured MPLS packet to a multicast distribution table virtual private local area network (VPLS) and multicast and redirect MPLS packet in accordance with information on next transition of each record of multiaddress distribution table in multicast distribution table VPLS.
EFFECT: technical result is providing a possibility to perform point-to-multipoint delivery on a service provider node, as well as to provide 1 + 1 or 1 + N protection on a service provider node.
