Abstract: A first network device in a first device group receives a first packet that is sent by a first terminal device connected to the first network device and whose destination address is an IP address of a second terminal device connected to a second network device in a second device group. When a first inter-group interconnection link exists between the first network device and the second device group, and congestion does not occur on the first inter-group interconnection link, the first network device sends the first packet to the second network device through the first inter-group interconnection link.

Abstract: A method and an apparatus for forwarding a packet, where a first network virtualization edge (NVE) receives a first packet sent by a first tenant end system (TES), where a destination Internet Protocol (IP) address of the first packet is an IP address of a second TES, a destination media access control (MAC) address of the first packet is a gateway MAC address corresponding to the first NVE. The first NVE acquires an access virtual network identifier (VN ID) and a layer 3 virtual private network (VPN) instance identifier of the first TES, and searches a routing and forwarding table, to obtain an entry corresponding to the IP address of the second TES. Then the first NVE encapsulates the first packet into a network virtualization overlays (NVO3) packet according to the entry, and forwards the NVO3 packet to a second NVE to forward to the second TES.

Abstract: A gateway receives a link state packet (LSP) that includes a network identifier of a Layer 2 virtual network and a multicast address and that is sent by each routing bridge (RB) that is on the Transparent Interconnection of Lots of Links (TRILL) network; separately performs calculation on the network identifier and the multicast address that are in each LSP, to obtain a calculation result corresponding to each combination of the network identifier and the multicast address; if the gateway determines that information preconfigured on the gateway matches a calculation result corresponding to a combination of the network identifier and the multicast address, sends a notification message including the network identifier and the multicast address that are in the matched combination to each RB; receives from at least one RB, a multicast packet corresponding to the multicast address in the matched combination, and forwards the multicast packet.

Abstract: A packet forwarding method and apparatus are described that pertain to the field of communication technologies. During selecting, from outbound interfaces of a plurality of forwarding chips, an outbound interface used for packet forwarding, a chassis-shaped device considers both: a role of the outbound interface (whether the outbound interface is an outbound interface of a shortest path or an outbound interface of a non-shortest path), and a congested state of the outbound interface. As such, the chassis-shaped device flexibly selects a forwarding path for a data packet based on a congestion situation of the forwarding path. In this way, an application of an adaptive routing technology is extended to the chassis-shaped device.
