[j-nsp] 4 byte as mixed with 2 byte recieving problem

[moki]

     We had a problem in our network with 4byte as client.

        Our network has a 2byte as.

        The customer have 4byte as and requested we add prepend (with our
as) to

        the path.

        When we added the prepend our edge routers mx480 with junos

        11.4R4 didn't accept the prefix from our route reflectors.

        We asked the customer to configure the prepend in its router and we
are

        working in this way.

        does anyone know whats the reason and what can i do to solve the

    problem ?

       Thanks.
