Usage guidelines
An NHLFE entry records label forwarding information, such as the outgoing label and outgoing interface.
NHLFE entries are mainly used to add multiple labels to packets. To add multiple labels to a packet, an
LSR first obtains the bottom label and NID in the matching FIB or ILM entry, and then obtains the outer
label in the NHLFE entry identified by the NID.
