    Abstract: A port number extension method and a switch are provided. A first switch determines bits for identifying the first switch in a Media Access Control (MAC) address in an identifier (ID) of a specified bridge; calculates a bit for port number extension according to the bits for identifying the first switch; and combines the bit for port number extension and original bits for specifying a port, to obtain new bits for specifying a port. In this way, a problem that Spanning Tree Protocol (STP) port numbers are insufficient in a super virtual fabric with a massive quantity of ports is resolved.

    Abstract: A route priority configuration method, a device, and a controller. The controller receives an interface creation request for creating a layer 3 interface on a target device, where the interface creation request carries an IP address and a subnet mask. The controller generates a direct route of the layer 3 interface based on the interface creation request; allocates a route priority to the direct route according to a preset allocation rule; and sends the direct route and the route priority corresponding to the direct route to the target device. According to the embodiments, direct routes generated based on a same IP address can correspond to different route priorities, to avoid a case in which direct routes advertised by different distributed gateways form ECMP, and improve route priority configuration efficiency.

    Abstract: A method for packet forwarding based on equal-cost multi-path and a network device, in order to resolve problems that are caused by inconsistent forwarding paths for packets in two directions of a same service flow in an equal-cost multi-path scenario. A first network device performs calculation on characteristic information in a packet using a hash algorithm to obtain a hash value, determines, according to a correspondence between hash values and path identifiers that is acquired in advance, a path identifier corresponding to the hash value, and forwards the packet to a second network device through a path that corresponds to the path identifier, where the path is one of the N equal-cost paths. There exist N equal-cost paths for packet forwarding between the first network device and the second network device. The same hash algorithm is configured on the two network devices respectively.
