Hello Mourad
Looking over your configs initially the only thing that needs modification is the addition of another static route on your spoke router to allow it to communicate with the subnet of the other spoke. Specifically:
ip route 192.168.3.0 255.255.255.0 192.168.2.22
This way communication between spokes can be successful. In your topology, each router is in a different subnet, while in the lesson, they’re in the same subnet, so this additional command is necessary. Note that you will have to enter the appropriate static route on the other spoke router as well.
Now NHRP in this particular case is used for learning spoke-to-spoke routes. Note in the lesson that the routing table of the spoke routers displays the route learned from the other spoke as an NHRP route. Resolving the routing problem mentioned before should bring up the NHRP operation. Give it a try and let us know how you get along.
I hope this has been helpful!
