Abstract
Techniques for leveraging Generic Routing Encapsulation (GRE) to carry monitored network traffic (i.e., network packets that are received and matched to a monitoring policy by a network monitoring system/fabric) are provided. In one set of embodiments, these techniques involve encapsulating a monitored packet using GRE by inserting the monitored packet in an unmodified form into a payload portion of a GRE packet and inserting metadata regarding the monitored packet into a header portion of the GRE packet, where the header portion employs a non-standard GRE header format that is designed to accommodate such metadata.
