    auto-export
    http://www.juniper.net/documentation/en_US/junos13.2/topics/reference/configuration-statement/auto-export-edit-routing-options.html

    Description
    Export routes between routing instances.

    This statement enables you to leak routes between VPN routing and forwarding (VRF) instances that are locally configured on a provider edge (PE) router. Auto export is always applied on the local PE router, because it applies to only local prefix leaking by evaluating the export policy of each VRF and determining which route targets can be leaked. The standard VRF import and export policies affect remote PE prefix leaking.

    You can use this statement as an alternative to using the VRF import and export policies.
