    GRE tunnel not working with Loopback interface

    Mihai

      Hello guys ,

       

      I am trying to send over tunnel some networks useing EIGRP as a rounting protocol(172.1.100.0 and 172.1.101.0). I use interfaces loopbacks as tunnel source and tunnel destinations learned by the routers with OSPF but the tunnel doesn't seem to work . Is it possible that Packet tracer doesn't support GRE when you use Loopback interfaces ?

       

      I've attached also the packet tracer config .

       

      Thank you and best regards,

      Mihai
