Abstract: A network node may receive a packet having an inner internet protocol (IP) header and an outer IP header. The inner IP header may be encrypted. A loose source routing (LSR) field of the outer IP header may identify a recipient address. The network node may determine, based on the recipient address identified in the LSR field, a tunnel endpoint associated with a receiving network node. The network node may update the outer IP header of the packet to obtain an updated packet with an updated outer IP header. A source address of the updated outer IP header may be updated to a tunnel endpoint associated with the network node, and the destination address of the updated outer IP header may be updated to a tunnel endpoint associated with the receiving network node. The network node may route the updated packet according to the updated outer IP header.
