exchange routes between global IP routing table and VRF routing table

    I understand that we can inject the global routes into the VRF routing
    table using ip route vrf vrf_name x.x.x.x y.y.y.y next_hop global
    command, and vice versa, however, my question is, is there any way to
    do it dynamicly (like using dynamic routing protocol)? Since
    currently, my customer VRF has a lot of public segment, e.g.
    A.x.x.x/8, B.y.y.y/8. They need to access Internet over MPLS VPN link,
    but I don't want to take care of every segment manually (using the
    static routes with global switch commands).

    If there is any way to do it dynamicly, please drop me a line, I
    appreciate any input and help.

    Need a few more details on this...

    How does the CE and PE talk? Are you using a dynamic routing protocol or
    Does the customer have multiple connections to you or a single one?
    Are you multihomed to the internet? (I assume yes to this one)
    Is the customer also multihomed to more than one service provider?

    CE and PE are connected by a POS link over EBGP. Let's take the
    simplest scenario here, just say, CE is connected only to my PE over
    one single link.

    My question is, on my PE, how can I inject the customer network
    segments into my global routing table dynamicly from the VRF routing
    table instead of static routing scheme. It's fine to inject the
    default gateway to the customer VRF from my global routing table, I am
    talking about the reverse direction. Since customer may have multiple
    public segments which are not continious, that means they are not able
    to be summarized, so I have to deal with each of them manually if I
    use static routing scheme.

    Thank you.
