摘要： A method for a network device to access a packet switched network is applied to a system in which the network device accesses the packet switched network by connecting to PEs in an active-standby mode. The method includes: an active PE and a standby PE each sends a fault detection message to the network device through an interface connected to the network device; the active PE sets the state of the interface to “up” and advertises a route to a remote PE if a fault detection response returned by the network device is received through the interface within a preset period; otherwise, the active PE sets the state of the interface to “down” , and withdraws the advertised route; and the standby PE sets the state of the interface to “up” and advertises another route to the remote PE after receiving a fault detection response through the interface connected to the network device.

The method includes: receiving a first L2VPN mapping packet from a first AS; parsing the first L2VPN mapping packet to obtain a first label carried in the first L2VPN mapping packet, applying for a second label which is different from the first label carried in the first L2VPN mapping packet, and generating a second L2VPN mapping packet according to the second label; and sending the second L2VPN mapping packet to a second AS. When multiple VPN users need to establish a multi-protocol label switching (MPLS) L2VPN between ASs, the MPLS L2VPN can be established between ASs through the technical solution under the present invention as long as a link exists between the ASs, thus providing high extensibility, high security, and convenient management of the inter-AS L2VPN.
