Abstract
A network device may receive, from a transmitting network device, a packet, wherein the packet includes a first outer internet protocol (IP) header, a Generic Routing Encapsulation (GRE) header, a second outer IP header, an Encapsulating Security Payload (ESP) header, and an inner packet, wherein the inner packet is encapsulated by the ESP header, the ESP header is encapsulated by the second outer IP header, the second outer IP header is encapsulated by the GRE header, and the GRE header is encapsulated by the first outer IP header. The network device may decapsulate the packet to remove the first outer IP header and the GRE header from the packet. The network device may decrypt, after decapsulating the packet, the packet to identify the inner packet. The network device may cause one or more actions associated with the inner packet to be performed.
