    Abstract: The present invention discloses a method, routing bridge, and system for sending a packet, which are applied to the field of communications technologies, and are invented to reduce a signaling overhead of a TRILL network. The method includes: receiving, by a first transit RB, a Nickname of an edge RB sent by a second transit RB; constructing, an address advertisement message, where the address advertisement message includes a virtual IP address and a virtual MAC address of the first transit RB; and sending, the address advertisement message to the edge RB according to the Nickname of the edge RB, so that the edge RB sends, after receiving the address advertisement message, a free ARP packet to a server that accesses the TRILL network through the edge RB, where the free ARP packet includes a correspondence between the virtual MAC address and the virtual IP address.

    Abstract: The present application relates to a method and an apparatus for switching between a master device and a backup device. The method for switching between a master device and a backup device includes: when an access device accesses a network by using the master device, detecting an interface that is on the master device and directly connected to the access device or a transmission device, so as to determine whether a link between the access device and the master device fails; and when it is determined that the link between the access device and the master device fails, instructing a redundancy group with a routing function to perform switching between the master device and the backup device, so that the access device accesses the network by using the backup device that is before the switching.
