    may be NHRP and mGRE can help u?
    this technology is used to support dynamic spoke's addreses in DMVPN.

    i presume following:
    static IP + mGRE tunnel interface + NHRP server at one side
    dynamic IP + GRE tunnel interface + NHRP client at another side


    NB: mGRE tunnel is always up
