Embodiment 1
[0041] This preferred embodiment 1 describes the automatic configuration process of VPN routing information and VRF interface information.
[0042] image 3 It is an interactive flowchart of the VPN interconnection method according to the preferred embodiment 1 of the present invention, such as image 3 As shown, the following steps S302 to S316 are included.
[0043] Step S302 , discover directly connected physical interface parameters between PE1 and PE2 , including system name, port name, and VLAN name. Through the LLDP protocol, static configuration, etc., the mutual direct connection physical interface parameter discovery can be performed. At the same time, you need to configure which of PE1 and PE2 is the active party that initiates the VRF interface configuration.
[0044] Step S304, establishing an MP-BGP signaling channel between PE1 and PE2 for exchanging information between PE1 and PE2, including VPN routing information, VRF interface information, and the like. ...
Embodiment 2
[0052] The second preferred embodiment describes the automatic configuration process of bandwidth information.
[0053] Figure 4 It is an interactive flowchart of the VPN interconnection method according to the second preferred embodiment of the present invention, such as Figure 4 As shown, the following steps S402 to S414 are included.
[0054] Step S402, establishing an MP-BGP signaling channel between PE1 and PE2 for exchanging information between PE1 and PE2.
[0055] Step S404, PE2 distributes routing information to PE1 through MP-BGP signaling, and carries corresponding bandwidth information at the same time. Here, a new MP-BGP route type needs to be defined to carry this routing information; the bandwidth information is the upstream egress bandwidth of this route.
[0056] In step S406, PE1 receives routing information from PE2, generates a corresponding routing entry, and uses the carried bandwidth information as the egress bandwidth of the route.
[0057] Step S...
