your help is much appreciated, I have an xconnect circuit between ASR1k and ASR9k, everything is fine accept no traffic is passing through three s only little packet that went through but no ping between hosts.

    Is ARP resolution working?
    Are you using large packets?

    On XE, hit "show xconnect all detail" or something like that. It should give you clues about what is happening.
