need help with setting up real equipment for ccie

The issue that I'm facing now is switch (cloud) or the trunks. In gns3 every work well. but when I tried to do this on the real equipment i'm not able to ping 169.254.100.x. I have configure the switch as switch trunk dot1q and switch mode trunk. CDP is set to run and enabled. For some reason the router is not able to arp for the 169.254.100.x. Please help

    I also used to think these were for microsoft dhcp failures, but this address space is in RFC-3330 - Special-Use IPv4 Addresses

    169.254.0.0/16 - This is the "link local" block. It is allocated for
    communication between hosts on a single link. Hosts obtain these
    addresses by auto-configuration, such as when a DHCP server may not
    be found.
