Hello Bahri

I’m assuming that your question has to do with the error message at the end that states:

% Cannot configure the local system as neighbor

If this is the case, then it seems that the IP address of 3.3.3.3 is being used by an interface on the local router. A router cannot create a neighbor relationship with itself. Check to see what other IP addresses are assigned to the router and make sure that 3.3.3.3 is not one of them.

I hope this has been helpful!
