Abstract:
Embodiments of the present invention disclose a method for connecting to a VPN across domains. The method includes: receiving, by a PE, a request message for connecting a VDC to a VPN sent by a DCG, determining an RD/RT list corresponding to a VPN User ID in the request message according to the User ID, so as to configure a VPN instance, determining a connection identity at a local end according to a connection identity at a DCG end of an AC in the request message, and binding a logical port in the connection identity at the local end with the VPN instance so that the VDC is connected to the VPN. Accordingly, the present invention further provides a PE and a DCG device for connecting to a VPN across domains.
Abstract:
The present invention 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.
