EIGRP over the Top

$

Hello,

 

I was trying today EIGRP over the top and i noticed something which makes me wonder why?

I have a basic topology with a core netork(R1,R2,R3) with iBGP enabled(config attached below)

R4,R5 and R6 are CE routers - EIGRP over the Top is enabled(config attached below)

    Once everything is ready, I can see the routes as expected

      R4(config)#do sho ip route eigrp

      Gateway of last resort is 172.16.14.1 to network 0.0.0.0
            192.168.1.0/32 is subnetted, 3 subnets
      D        192.168.1.5 [90/94501211] via 172.16.25.5, 00:53:29, LISP1
      D        192.168.1.6 [90/94501211] via 172.16.36.6, 00:53:26, LISP1



      R5(config)#do sho ip route eigrp

      • The problem starts when I'm trying to send traffic between CE's loopbacks
