Title:
MESSAGE SENDING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/017225
Kind Code:
A1
Abstract:
The present application relates to the technical field of EVPN and provides a message sending method, device and system. In the solution provided by the present application, when a link fault between a first PE device and a CE device causes a DF device to be switched from the first PE device to a second PE device, the first PE device sends a first message to the second PE device, so that the second PE device forwards the first message to the CE device. Thus, the CE device, on the basis of the first message forwarded by the second PE device, timely generates or updates an MAC table entry, and on the basis of the MAC table entry, sends a message to the second PE device. Furthermore, the message from the CE device can be forwarded by the second PE device which is switched as the DF device, so that normal forwarding of uplink traffic sent by the CE device can be ensured, and interruption of the uplink traffic of the CE device is avoided.
