In the Cisco Catalyst SD-WAN solution, the overlay network is controlled by the Overlay Management Protocol (OMP). All the routes are advertised and learned via OMP. Depending on the network topology, some routes might be advertised from multiple routers. In this session, participants will understand how the OMP operates, the algorithm behind it, and how to tune OMP parameters to influence the overlay routing of the network. This session will help participants to familiarize with UX 2.0 configuration groups and policy groups.
