[lir-wg] Question to a multihomed PA-space connection

Hello,

I have "little" question (but notice that I'm not a guru in BGP-routing and
RIPE-problems).
We want to connect a customer which don't want to register as a new AS. But
he wants a connect to 2 provivers (different AS's).
We have tried to get PI-space from RIPE but the automaticly response told us
the following:
-------- Quote --------
1. Why is PI space required rather than PA space?

    -  If PI is requested for multi-homing please explain why the
    second provider cannot route PA space as a more specific
    route(with the PA block holder adding a more specific route
    too).

    - The same policies apply to PI space as PA. Administrative ease
    and/or routing are not reasons for PI. Please read the information
    about PA/PI from the RIPE Document, IPv4 Address Allocation and
    Assignment Policies in the RIPE NCC Service Region, Sections 5.1.5
    and 5.1.6:
-------- Unquote --------

Can anyone tell me what is to do for that the second provider is able to
announce the /24-PA from the first provider (to emulate a multihomed
connection) or is it only possible to use the second provider for backup
with the same space?

wait hopefully for tips or hints

regards,
Janko Thoß
