Abstract:
The present application provides a packet sending method and a network device. The packet sending method includes: receiving, by a network device, a first data packet; and if a MAC entry matching a destination MAC address of the first data packet is not found in a media access control MAC address table of the network device, sending, by the network device, the first data packet according to a forwarding behavior in a MAC default entry of the MAC address table. When the MAC entry matching the destination MAC address of the first data packet is not found, the network device does not need to flood the first data packet on all interfaces, but directly sends the first data packet according to the MAC default entry in the own MAC address table, thereby reducing a need for MAC address capacity in the network device, and not increasing unnecessary network traffic.

Claim (Index 4):
The method according to  claim 2 , wherein the network device comprises a provider edge (PE) device;\n before the receiving, by the network device, the data packet, the method further comprises: receiving, by the PE device, an update message sent by a route reflector, wherein the update message sent by the route reflector carries network layer reachability information, a next hop address and a route target attribute, wherein the network layer reachability information comprises the default MAC address, the next hop address is an address of the route reflector, and the route target attribute is used to identify a virtual private network that the default MAC address belongs to; determining, by the PE device, a tunnel between the PE device and the route reflector according to the next hop address, and generating, according to the network layer reachability information and the next hop address, the MAC default entry of the virtual private network identified by the route target attribute, wherein the forwarding behavior in the MAC default entry of the virtual private network comprises sending, via the tunnel between the PE device and the route reflector, the data packet received by the PE device to the route reflector; and storing, by the PE device, the MAC default entry of the virtual private network.
