remarks:        Level 3 does not allow any part of 4.0.0.0/8 to be
remarks:        multihomed.
remarks:
remarks:        If you are a customer who is currently using address
remarks:        space from 4.0.0.0/8 and if you need to multihome your
remarks:        network to another provider, please contact Level 3 for
remarks:        new address space which can be multihomed.
remarks:
remarks:        If you are a provider who has been asked to route a
remarks:        more-specific network block that is part of 4.0.0.0/8,

remarks:        a new network block.
remarks:
remarks:        Level 3 will not accept advertisements for any networks
remarks:        that are part of 4.0.0.0/8 from any non-customer peer.
remarks:
remarks:        Note that the import/export designations above are a
remarks:        simplification of our actual policies which cannot
remarks:        be properly described given the limitations of RPSL
remarks:        They would also be rather tedious to read if we
remarks:        denoted all of the common policy bits applied to every
remarks:        peer, so we have only noted the peer-specific bits.
remarks:
remarks:        We have also only documented our customer peers in this
remarks:        object at this time.
remarks:
remarks:        The following import actions are common to every

remarks:        stripped from them at ingress, and any communities
remarks:        meant to affect localpref, prepending, etc are thus
remarks:        ignored.
remarks:
remarks:        - All customer peering sessions are prefix-filtered

remarks:
remarks:        - Any subnet of any Level 3 CIDR block (as documented
remarks:        in rs-Level3) is not accepted unless routing for the
remarks:        subnet in question has been explicitly requested by

remarks:        to 86.
remarks:
remarks:        - A hard limit is placed on the number of routes a peer
