Abstract: Embodiments of the present disclosure provide a network logical layering method based on Routing In Fat Tree (RIFT) protocol, a network logical layering device, a network device and a storage medium. By exchanging Link Information Element (LIE) packets and Topology Information Element (TIE) packets with other devices, a network device can enable the other devices in the network to know a topology supported by the present device and to know neighbor information and Metric information of the present device in the supported topology, and the network device can also know the topologies supported by the other devices in the network and the neighbor information and the Metric information of the other devices in the corresponding topologies. Thus, the device can calculate a topology route corresponding to the topology supported thereby.

Abstract: A path construction method and related devices are disclosed. The method may include: advertising, by a second PE node, a first VPN route to a first PE node through an MP-BGP signaling channel, such that the first PE node is able to determine a label forwarding path to a first VPN Prefix based on a first transmission path descriptor (TPD) carried in the first VPN route received; where the first TPD is configured to identify the label forwarding path for a first VPN message to reach a BGP next hop.

Abstract: The present application provides parameter notification and obtaining methods and devices. The parameter notification method comprises: a first node determines parameters comprised in non-default maximally redundant tree (MRT) Profile; the first node notifies the parameters comprised in the non-default MRT Profile to a second node by means of interior gateway protocol (IGP) extensions. Embodiments of the present application also provide a computer storage medium.

Abstract: Disclosed are a message forwarding method and apparatus, and a node. The method comprises: receiving an Internet Protocol Version 6 (IPv6) message encapsulated by a Segment Routing Header (SRH), by a node with a IPv6 Segment Routing (SRv6) forwarding capacity, wherein the SRH includes a segment list; and determining, by the node, that it is a node corresponding to a penultimate segment in the segment list, and popping the SRH by the node before forwarding the IPv6 message.

Abstract: Provided are a multicast cross-domain method, device and system, and a computer readable storage medium. The method includes: dividing nodes in each domain of a multi-domain network into a multicast proxy nodes and a common nodes; sending, by the common nodes, a subscription request to a multicast source node outside the each domain through the multicast proxy nodes in the each domain; sending, by the multicast source node, a bit indexed explicit replication (BIER) multicast message obtained through BIER encapsulation to the multicast proxy nodes; and sending, by the multicast proxy nodes, the BIER multicast message to the common nodes.
