In the LTE service, X2 traffic forwarding between base stations needs to be enabled.
Which of the following statements about the forwarding path in the x2 traffic flow is correct?

  1. X2 traffic forwarding on the same network segment does not require Layer 3 routes or interfaces
  2. 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
  3. 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.
  4. X2 traffic forwarding between different cities requires SGW participation

Answer(s): B
