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 does the following:
1. Obtains the bottom label and NID in the matching FIB or ILM entry.
2. Obtains the outer label in the NHLFE entry identified by the NID.
