    D

    AII PE routers that link the backbone carrier to the customer carrier must run Route Target Rewrite.

    E

    Arouting protocol is required between the PE and CE routers that connect the backbone carrierto thecustomer carrier. The routing protocol enables the customer carrier to exchange IGP routing information with the backbone carrier.
