MPLS label allocation failure

I was playing with a test MPLS network today and I saw that my LSP isn’t UP.  When I checked with the show mpls command , I have seen the following “MPLS label allocation failure” message.
Then I checked the router to troubleshoot the issue. The issue was again I forgot to enable mpls at interface level.


Once I added the “family mpls” to the interfaces, all started working fine. Then I enforced some path for my LSP and then I got the following “No route toward dest” error.

This time error was the missing mpls family on the exit interface of device. Again it worked when I fixed this error. It seems I need some time on this topic:)
