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 discloses a link discovery method and apparatus. The method includes: when a network device receives a first LLDP packet sent by a directly connected device, determining a security level of the directly connected device according to an authentication TLV; if the security level of the directly connected device is secure, determining a device type of the directly connected device, and sending a second LLDP packet to the directly connected device according to a correspondence between the device type of the directly connected device and a TLV. In the present application, a corresponding TLV is selected according to the device type and sent, which avoids that all types of TLVs are sent to a directly connected device every time, and reduces a possibility of device information leakage. It is ensured that a sent LLDP packet is more proper, and a link overhead is reduced.
