https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/routing/vEdge-20-x/routing- book/m-unicast-routing.html A Cisco vSmart Controller learns the same OMP route, 10.10.10.0/24, from two Cisco vEdge devices in the same site. If all other parameters are the same, both routes are chosen and advertised to other OMP peers. By default, up to four equal-cost routes are selected and advertised.
