Configuring Proxied Vehicle-Mounted Devices

After the vehicle-mounted AP switches the active link to a new trackside AP, ground network devices cannot detect the link handover and still forward data to the original trackside AP, causing a data transmission failure. To prevent this situation, you can configure proxied vehicle-mounted devices on the vehicle-mounted AP so that the vehicle-mounted AP can instruct the ground network devices to update MAC forwarding entries on interfaces after the active link is switched to a new trackside AP. In this way, data traffic from the ground network can be forwarded to the trackside AP.
