NO.107 Regarding the MPLS forwarding process, which of the following description of Ingress node forwarding is correct? (Multiple choice)

After receiving the data packet, the Ingress node will first check the ILM table to find the Tunnel ID

Press the obtained label in the IP packet, and process EXP according to the QoS policy, and process L at the same time, and then send the encapsulated MPLS packet to the next hop

Find the corresponding NHLFE entry according to the Tunnel ID of the ILM table, and associate the LFIB entry with the NHLFE entry

Check the NHLFE entry, you can get the outgoing interface, next hop, outgoing label, and label operation type. The label operation type is Push
