If an edge Label Switch Router (LSR) is properly configured,which three combinations are possible?()
A

A received IP packet is forwarded based on the IP destination address and the packet is sent as an IP packet.

B

An IP destination exists in the IP forwarding table. A received labeled packet is dropped because the label is not found in the LFIB table.

C

There is an MPLS label-switched path toward the destination. A received IP packet is dropped because the destination is not found in the IP forwarding table.

D

A received IP packet is forwarded based on the IP destination address and the packet is sent as a labeled packet.

E

A received labeled IP packet is forwarded based upon both the label and the IP address.

F

A received labeled packet is forwarded based on the label. After the label is swapped,the newly labeled packet is sent.
