ECMP supports and complements static routes.
When ECMP is globally enabled, the equal cost static routes are added in the Routing Table Manager (RTM).
Static routes that are configured only using an interface, such as VLAN or port, do not support ECMP as these routes have a preference value of 0 and are treated like local routes.
If your switch supports a management interface, then static routes configured on the management interface do not support ECMP.
Static routes configured by next-hop are not considered equal cost with routes that are configured by tunnel even if the routes have the same cost and preference.
A static route configured by tunnel is the least preferred and is programmed only when a next-hop or an interface does not configure a static route.
Static routes configured by next-hop that resolves their next-hop using another static route will be in the notReachable state even if the next-hop can be pinged.
If there are two static routes configured by next-hop, and both next-hops are resolved via a dynamic protocol to the same value, then only one route will be in the reachableInRtm state. The state of the other route will be reachableNotInRtm.
