What is wrong in the following description of the base station configuration?

In a layer 3 network, the VLAN ID of the X2 interface of eNodeB and gNodeB must be the same for normal communication

In a layer 3 network, the VLAN ID of the X2 interface of eNodeB and gNodeB must be the same for normal communication

When configuring routing, if the destination address is a network segment, the mask of the destination address cannot be 32 bits

SCTP port number is a negotiation parameter, you can plan it yourself within a certain range to ensure consistency at both ends

The source address routing configuration has nothing to do with the IP of the opposite end, so the opposite end does not need to configure routing, and normal communication can also be guaranteed
