A. The outer label of MPLS VPNE is assigned by the LDP protocol or statically, and the inner label is assigned by the MP-BGP neighbor of the correct end
B. By default the outer label is popped before the packet is forwarded to the last hop device
C. The outer label is used to correctly send the data packet to the corresponding VPN on the PE device
D. The outer label of MPLS VPN is called the private network label and the inner label is called the public network label
