Embodiment 1
[0060] The embodiment of the present invention provides a method for switching Ethernet virtual network gateways, see image 3 , the method includes:
[0061] Step 101: The first service provider edge node PE monitors the state of a first virtual routing redundancy protocol VRRP gateway, and the first VRRP gateway and the first PE are in a first data center.
[0062] When the state of the first VRRP gateway is active, the first PE uses the MAC route of the first VRRP gateway to forward traffic.
[0063] Step 102: When the state of the first VRRP gateway is abnormal or standby, clear the MAC route of the first VRRP gateway on the first PE, and obtain the MAC route of the second VRRP gateway sent by the second PE , and use the MAC route of the second VRRP gateway to forward traffic. Wherein, the second VRRP gateway and the second PE are in a second data center, the second data center is a data center adjacent to the first data center, and the first data center and the first da...
Embodiment 2
[0067] based on figure 2 In the system shown, the embodiment of the present invention also provides a method for switching Ethernet virtual network gateways, see Figure 4 , the method includes:
[0068] Step 201: the first PE monitors local VRRP packets.
[0069] In this embodiment, the local VRRP message is a VRRP message sent by the first VRRP gateway, that is, a VRRP message sent by a VRRP gateway in the same data center as the first PE.
[0070] The VRRP gateway in the active state will regularly send VRRP packets, that is, VRRP notification packets (there is only one type of VRRP packet), to notify the VRRP gateway in the backup state that it is working normally. A VRRP packet includes a VRRP ID and a priority. The VRRP ID ranges from 1 to 255, and the priority ranges from 0 to 255. A larger value indicates a higher priority. Of course, the VRRP message also includes other fields, such as VLAN, authentication data, checksum, and so on.
[0071] VRRP packets are enca...
Embodiment 3
[0099] An embodiment of the present invention provides a service provider edge node device PE, see Figure 5 , the PE includes:
[0100] A monitoring module 301, configured to monitor the status of a first virtual routing redundancy protocol VRRP gateway, the first VRRP gateway and the PE are in the first data center;
[0101] The processing module 302 is configured to clear the MAC route of the first VRRP gateway on the PE when the state of the first VRRP gateway is abnormal or standby, and obtain the MAC address of the second VRRP gateway sent by the second PE. route, and use the MAC route of the second VRRP gateway to forward traffic, the second VRRP gateway and the second PE are in a second data center, and the second data center is adjacent to the first data center data center, the first data center is connected to the second data center through an IP tunnel.
[0102] The processing module 302 is further configured to use the MAC route of the first VRRP gateway to forwa...
