Abstract
Techniques for generating and utilizing overlay-based Border Gateway Protocol (BGP) Operations, Administration, and Maintenance (OAM) packets to detect issues with an underlay network. The techniques may include receiving, from a BGP peer device via a control plane path, an OAM probe indicating a forwarding path to be used for sending the traffic to a destination associated with a prefix. The techniques may also include determining, based at least in part on the OAM probe, that a next-hop device is incapable of being utilized to forward the traffic to the destination, the next-hop device determined based on an origination of the prefix. The techniques may further include performing a policy-based action based at least in part on determining that the next-hop device is incapable of being utilized to forward the traffic to the destination.
