In the campus SDN solution, which statement is wrong about the distributed gateway solution?
A . In distributed gateway-VxLAN to access, independent AC scenarios, local forwarding mode deployment is not recommended for wireless traffic.
B . Distributed gateway-VxLAN to access, independent AC scenario, enter VN from edge, execute business mobility policy on edge (edge needs to subscribe to IP-Group service), the current solution supports automated deployment.
C . The VTEP device is both an L2 gateway and an L3 gateway. Non-gateway nodes are not aware of VXLAN tunnels and only serve as forwarding nodes for VXLAN packets.
D . In the distributed gateway-VxLAN to aggregation, on-board AC scenario, the accompanying policy for wireless traffic services is executed on the edge, and tunnel forwarding is recommended.
