Packet forwarding
A first VXLAN tunnel is established between a gateway device and an aggregation switch which corresponds to a BRAS group including several BRAS network elements. A second VXLAN tunnel is established between the gateway device and each of the BRAS network elements. In an example, when receiving a first VXLAN packet from the aggregation switch through the first VXLAN tunnel, the gateway device may acquire a first user packet by de-encapsulating the first packet and forward an encapsulated first user packet to the BRAS network element through the second VXLAN tunnel by VXLAN encapsulating the first user packet. In turn, the gateway device may receive a second VXLAN packet from the BRAS network element through the second VXLAN tunnel and forward a corresponding encapsulated second user packet to the aggregation switch through the first VXLAN tunnel.
