I have big problem on ASR 1001X , it connected back to back to one device . The interface is up but no ping . However if i disconnect this cable from ASR and connect to Core switch the ping is working. The ASR1001X use GBIC nterface to be connect to the next hop " internet Modem", also i connect back to back to the modem the interface is reachable.
configuration as below:-
interface g0/0/3
