X2 traffic forwarding on the same network segment does not require Layer 3 routes or interfaces

For forwarding in the X2 flow between base stations on different network segments under the same L2L3 node, it is necessary to transfer between L3VE sub-interfaces

Different L2L3 nodes must forward the X2 traffic with the base station to the base station, and it must be transited by the L3 node.

X2 traffic forwarding between different cities requires SGW participation

MST is both the source and sink of MS

MST implements BIP-8 statistical calculation of B2 bytes.

MST returns bit error information, but does not return a specific number of bit errors.

MST provides its rdenire channel.
