    Hi,

    I am aware that prcloning is removed in current-5, but do have a question as I
    still have some boxes running 4.x custom code.

    My assumption of PRCLONING existance is to assist TCP applications (i.e. host
    cache) to use routing table as its caching mechanism.. Is this a correct
    assumption?

    And, if that is true, would it hurt to remove prcloning feature off of the 4.x
    routing code? What kind of breakage would I expect in doing so with tcp apps?
    I'd figure as long as they can find a prefix to get out to the world, and
    doesn't have to be a /32 prcloned route, it would be ok, no?

    Thanks for the tips :)
    -J
