Network Requirements

Your network must use a single-mode fiber with a 1GE or 10GE optical module to connect to the access device in the cloud.
Auto-negotiation for the port must be disabled.
Port speed and full-duplex mode must be manually configured.
802.1Q VLAN encapsulation must be supported on the entire connection, including intermediate devices.
If BGP routing is used, your device must support BGP and BGP MD5 authentication.
(Optional) You can configure Bidirectional Forwarding Detection (BFD) on the network.
The maximum transmission unit (MTU) supported at the physical layer is 1522 bytes (14-byte Ethernet header + 4-byte VLAN tag + 1500-byte IP datagram + 4-byte frame check sequence).
Private IP addresses are recommended on the cloud, and IP address ranges for interworking cannot conflict with each other.
