Overview

Explains the Overlay Management Protocol (OMP) as the control plane protocol responsible for establishing and maintaining the Cisco SD-WAN overlay network. OMP manages routing, policy, and security information exchange between Cisco SD-WAN Controllers and edge devices. It provides operational details, limitations, and configuration procedures.

Feature history for OMP

Lists the development milestones and release information for OMP, including feature description.

OMP routing mechanisms for Cisco SD‑WAN overlay networks

Explains how OMP orchestrates the overlay network by separating services from transport and distributing routing, policy, and security information.

OMP route advertisements

Describes how OMP learns and advertises vRoutes (prefixes) and TLOCs (transport locations) to establish network reachability.

OMP paths

Discusses the exchange of TLOC information and the configurable limits on the number of paths shared between controllers.

OMP route redistribution

Details which protocols are automatically redistributed into OMP (like Static and Connected) and which require explicit configuration (like BGP and EIGRP).

OMP graceful restart

Explains a resiliency mechanism that allows data traffic to continue forwarding using cached information if the control plane connection is lost.

OMP vRoute advertisement optimization using system path

Describes a memory-saving feature that flattens advertisements from a per-TLOC basis to a per-System IP basis.

Configure OMP

Follow these procedures to implement OMP routing on your devices.
