How to move player along navmesh link's curve?

Question

NavMesh Link creates a navigable link between two locations that use NavMeshes.

This link can be from point to point or it can span a gap, in which case the Agent uses the nearest location along the entry edge to cross the link.

I don't know why when I use navmesh link player move along horizontal plane (that I demonstrate it by red line) between gaps in navmesh link Is there a option that player jump along curve (that I demonstrate it green curve)? should I use force?

you can see player move horizontally! that isn't interesting. Offmesh Links - Unity Official Tutorials

The navmesh links are curved only for visual fidelity.
In reality, they only store a start and end point (and some metadata).

If you want your agent to jump when encountering a link, you would need to do that yourself.
One way to do that is described in this forum post.

using UnityEngine;
using System.Collections;
public enum OffMeshLinkMoveMethod {
 Teleport,
 NormalSpeed,
 Parabola,
 Curve
}
[RequireComponent (typeof (NavMeshAgent))]
public class AgentLinkMover : MonoBehaviour {
 public OffMeshLinkMoveMethod method = OffMeshLinkMoveMethod.Parabola;
 public AnimationCurve curve = new AnimationCurve ();
 IEnumerator Start () {
 NavMeshAgent agent = GetComponent<NavMeshAgent> ();
 agent.autoTraverseOffMeshLink = false;
 while (true) {
 if (agent.isOnOffMeshLink) {
 if (method == OffMeshLinkMoveMethod.NormalSpeed)
 yield return StartCoroutine (NormalSpeed (agent));
 else if (method == OffMeshLinkMoveMethod.Parabola)
 yield return StartCoroutine (Parabola (agent, 2.0f, 0.5f));
 else if (method == OffMeshLinkMoveMethod.Curve)
 yield return StartCoroutine (Curve (agent, 0.5f));
 agent.CompleteOffMeshLink ();
 }
 yield return null;
 }
 }
 IEnumerator NormalSpeed (NavMeshAgent agent) {
 OffMeshLinkData data = agent.currentOffMeshLinkData;
 Vector3 endPos = data.endPos + Vector3.up*agent.baseOffset;
 while (agent.transform.position != endPos) {
 agent.transform.position = Vector3.MoveTowards (agent.transform.position, endPos, agent.speed*Time.deltaTime);
 yield return null;
 }
 }
 IEnumerator Parabola (NavMeshAgent agent, float height, float duration) {
 OffMeshLinkData data = agent.currentOffMeshLinkData;
 Vector3 startPos = agent.transform.position;
 Vector3 endPos = data.endPos + Vector3.up*agent.baseOffset;
 float normalizedTime = 0.0f;
 while (normalizedTime < 1.0f) {
 float yOffset = height * 4.0f*(normalizedTime - normalizedTime*normalizedTime);
 agent.transform.position = Vector3.Lerp (startPos, endPos, normalizedTime) + yOffset * Vector3.up;
 normalizedTime += Time.deltaTime / duration;
 yield return null;
 }
 }
 IEnumerator Curve (NavMeshAgent agent, float duration) {
 OffMeshLinkData data = agent.currentOffMeshLinkData;
 Vector3 startPos = agent.transform.position;
 Vector3 endPos = data.endPos + Vector3.up*agent.baseOffset;
 float normalizedTime = 0.0f;
 while (normalizedTime < 1.0f) {
 float yOffset = curve.Evaluate (normalizedTime);
 agent.transform.position = Vector3.Lerp (startPos, endPos, normalizedTime) + yOffset * Vector3.up;
 normalizedTime += Time.deltaTime / duration;
 yield return null;
 }
 }
}
