       * towards LAN -> WAN: PPPoE/PPP headers are deleted from the packet, ''srcMAC := bras_arp_mac'', ''dstMAC := bras_gateway_mac''   * towards LAN -> WAN: PPPoE/PPP headers are deleted from the packet, ''srcMAC := bras_arp_mac'', ''dstMAC := bras_gateway_mac''
       * towards WAN -> LAN: PPPoE/PPP headers are added to the packet, ''srcMAC := bras_arp_mac'', ''dstMAC := subscriber's MAC address''. If the PPPoE session is not found by its IP address, the packet will be dropped.   * towards WAN -> LAN: PPPoE/PPP headers are added to the packet, ''srcMAC := bras_arp_mac'', ''dstMAC := subscriber's MAC address''.

     All the traffic termination features are supported, including VLAN/Q-in-Q tags in PPPoE traffic along with its termination. All the traffic termination features are supported, including VLAN/Q-in-Q tags in PPPoE traffic along with its termination.

     The [[en:dpi:bras_bng:bras_l2_vlan_term:bras_l2_vlan_term_as|AS termination]] mode is not applied to PPPoE traffic, since the PPPoE packets don't alway contain the IP address, so generally the AS cannot be recognized. The [[en:dpi:bras_bng:bras_l2_vlan_term:bras_l2_vlan_term_as|AS termination]] mode is not applied to PPPoE traffic, since the PPPoE packets don't alway contain the IP address, so generally the AS cannot be recognized.
