In the multi-campus interconnection LAN-WAN convergence scenario, refer to the following topology [Campus topology-8 [The...

Synchronize information between dual-gateway devices through the interlink control sub-interface, such as the synchronization and backup of application recognition results, overlay connection information, and connection quality information. Interlink serves as a dual-gateway device interconnection interface that forwards inter-device (VPN) traffic through sub-interfaces.

Interlink serves as a dual-gateway device interconnection interface, providing forwarding of inter-device service (VPN) traffic through sub-interfaces.

Interlink can be interconnected with a direct link, and when the site service traffic is large and the CPE port resources are sufficient, it is recommended that Interlink use an Eth-trunk link. Interlink cannot borrow Layer 2 service interfaces on the CPELAN side.
