Abstract
In some implementations, an ingress network device of a multiprotocol label switching (MPLS) network may receive a packet destined for a destination network device. The ingress network device may determine, based on the packet, a secure function to secure the packet and a label associated with a label-switched path (LSP) from the ingress network device to an egress network device of the MPLS network that is associated with the destination network device. The ingress network device may encrypt, using the secure function, the packet to generate an encrypted packet. The ingress network device may generate an MPLS packet comprising: an MPLS header that includes the label and a secure function indicator, a secure MPLS data header that includes information identifying the secure function, and an MPLS payload that includes the encrypted packet. The ingress network device may forward, based on the label, the MPLS packet.
