    Actually, that isn't quite correct. You do not need a virtual IP
    address (such as an HSRP or VRRP setup). You just need equal cost
    paths from the ISP to you.

    To achieve this you will need to route an address range from your
    ISP to your network. It can be your address space, a small piece
    of ISP provided space, or even a chunk of private space. Just as
    long as it's routed from the ISP to you via the DSL tails. The
    ISP just needs to see equal cost paths to your prefix via BOTH
    your DSL tails. That way they will use both.

    There are several ways to do this (inc running eBGP or OSPF to them
    from your equipment). Have a chat with your ISP to see what options
    they would consider.
