remarks: The size of the import/export data in this object has
remarks: been causing problems for the RIPE routing registry

remarks: been removed. Please perform a whois query against
remarks: rr.Level3.net if you wish to see this information.

remarks:
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: please ask your customer to contact Level 3 to obtain
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: Level 3 customer peering session:
remarks:
remarks: - RFC1918 and other reserved networks and subnets are
remarks: not permitted.
remarks:
remarks: - Advertisements with reserved ASes in the path
remarks: (ie 64512 - 65535) are not permitted.
remarks:
remarks: - Prefixes shorter than /8 are not permitted.
remarks:
remarks: - Advertisements containing the AS of a network with
remarks: which we have a non-customer peering relationship
remarks: are not permitted (ie customers are not allowed
remarks: to advertise transit for Sprint, AT&T, etc).
remarks:
remarks: - Advertisements tagged with our own "internal use only"
remarks: communities (ie the city/country/region/etc communities
remarks: outlined below) will have all of their communities
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: inbound using a customer specified import policy
remarks: pulled from any known public registry.
remarks:
remarks: - Prefixes not matching the per-peer import policy
remarks: as documented above are not permitted.
remarks:
remarks: - Localpref will be set to 100 by default, subject
remarks: to modification based on received communities as
remarks: outlined below.
remarks:
remarks: - A hard limit is placed on the number of routes a peer
remarks: is allowed to announce to us. This number is based
remarks: on their registered routes plus a bit of extra
remarks: overhead.
remarks:
remarks: The following import actions are common to every
remarks: Level 3 non-customer peering session:
remarks:
remarks: - RFC1918 and other reserved networks and subnets are
remarks: not permitted.
remarks:
remarks: - Advertisements with reserved ASes in the path
remarks: (ie 64512 - 65535) are not permitted.
remarks:
remarks: - Prefixes shorter than /8 or longer than /24 are
remarks: not permitted.
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: the multihomed customer in question. If you are a
remarks: customer wishing to multihome a Level 3 CIDR block
remarks: please contact the Technical Support Center at
remarks: 877-4LEVEL3 or through the customer online portal.
remarks:
remarks: - Advertisements tagged with our own "internal use"
remarks: or "customer use" communities (as outlined below)
remarks: will have all of their communities stripped from them
remarks: at ingress.
remarks:
remarks: - MEDs are overwritten unless special arrangements
remarks: have been made.
remarks:
remarks: - Peers who register their routes with meaningful
remarks: policies may have a prefix filter applied based on
remarks: this policy.
remarks:
remarks: - Localpref for non-customer peers is generally set
remarks: to 86.
remarks:
remarks: - A hard limit is placed on the number of routes a peer
remarks: is allowed to announce to us. This number is based
remarks: on their registered routes or on a historical view of
remarks: the number of routes they have been advertising plus
remarks: a bit of extra overhead.
remarks:
remarks: The following export actions are common to every
remarks: Level 3 peering session:
remarks:
remarks: - RFC1918 and other reserved networks and subnets are
remarks: not announced.
