When two OMP routes are learned from the same SD-WAN device, which route is preferred?

When multiple OMP routes to the same destination are learned from the same SD-WAN device, the router prefers the route with the lower administrative distance. This is a fundamental routing principle: a lower administrative distance indicates a more trustworthy source. If administrative distances are equal, other tie-breakers like the origin type (e.g., connected, static, OSPF) and then the origin metric would be considered. The OMP route preference value is used when routes are learned from different SD-WAN devices. Router ID is used in protocols like OSPF and BGP for loop prevention and path selection, but not as a primary tie-breaker for routes from the same OMP peer.
