Level 3 does not allow any part of 4.0.0.0/9 to be
multihomed.
If you are a customer who is currently using address
space from 4.0.0.0/9 and if you need to multihome your
network to another provider, please contact Level 3 for
new address space which can be multihomed.
If you are a provider who has been asked to route a
more-specific network block that is part of 4.0.0.0/9,
please ask your customer to contact Level 3 to obtain
a new network block.
Level 3 will not accept advertisements for any networks
that are part of 4.0.0.0/9 from any non-customer peer.
Note that the import/export designations above are a
simplification of our actual policies which cannot
be properly described given the limitations of RPSL
They would also be rather tedious to read if we
denoted all of the common policy bits applied to every
peer, so we have only noted the peer-specific bits.
We have also only documented our customer peers in this
object at this time.
The following import actions are common to every
Level 3 customer peering session:
- RFC1918 and other reserved networks and subnets are
not permitted.
- Advertisements with reserved ASes in the path
(ie 64512 - 65535) are not permitted.
- Prefixes shorter than /8 are not permitted.
- Advertisements containing the AS of a network with
which we have a non-customer peering relationship
are not permitted (ie customers are not allowed
to advertise transit for Sprint, AT&T, etc).
- Advertisements tagged with our own "internal use only"
communities (ie the city/country/region/etc communities
outlined below) will have all of their communities
stripped from them at ingress, and any communities
meant to affect localpref, prepending, etc are thus
ignored.
- All customer peering sessions are prefix-filtered
inbound using a customer specified import policy
pulled from any known public registry.
- Prefixes not matching the per-peer import policy
as documented above are not permitted.
- Localpref will be set to 100 by default, subject
to modification based on received communities as
outlined below.
- A hard limit is placed on the number of routes a peer
is allowed to announce to us. This number is based
on their registered routes plus a bit of extra
overhead.
The following import actions are common to every
Level 3 non-customer peering session:
- RFC1918 and other reserved networks and subnets are
not permitted.
- Advertisements with reserved ASes in the path
(ie 64512 - 65535) are not permitted.
- Prefixes shorter than /8 or longer than /24 are
not permitted.
- Any subnet of any Level 3 CIDR block (as documented
in rs-Level3) is not accepted unless routing for the
subnet in question has been explicitly requested by
the multihomed customer in question. If you are a
customer wishing to multihome a Level 3 CIDR block
please contact the Technical Support Center at
877-4LEVEL3 or through the customer online portal.
- Advertisements tagged with our own "internal use"
or "customer use" communities (as outlined below)
will have all of their communities stripped from them
at ingress.
- MEDs are overwritten unless special arrangements
have been made.
- Peers who register their routes with meaningful
policies may have a prefix filter applied based on
this policy.
- Localpref for non-customer peers is generally set
to 86.
- A hard limit is placed on the number of routes a peer
is allowed to announce to us. This number is based
on their registered routes or on a historical view of
the number of routes they have been advertising plus
a bit of extra overhead.
The following export actions are common to every
Level 3 peering session:
- RFC1918 and other reserved networks and subnets are
not announced.
- Advertisements with reserved ASes in the path

- Prefixes shorter than /8 or longer than /24 are
not announced.
- Any subnet of any Level 3 CIDR block (as documented
in rs-Level3) is not announced unless routing for the
subnet in question has been explicitly requested by
the multihomed customer in question.
- Suppression and prepend actions as outlined in the
community list below are taken for announcements to
non-customer peers.

3356:9999 - blackhole (discard) traffic
Traffic destined for any prefixes tagged with this
community will be discarded at ingress to the Level 3
network. The prefix must be one permitted by the
customer's existing ingress BGP filter.
For some router vendors the peering
must be changed to an eBGP multihop session on the Level
3 side of the connection.
Please contact noc.coreip@lumen.com with any questions
regarding this functionality.

customer traffic engineering communities - Blackhole
--------------------------------------------------------
3356:9999 - blackhole (discard) traffic
Traffic destined for any prefixes tagged with this
community will be discarded at ingress to the Level 3
network. The prefix must be one permitted by the
customer's existing ingress BGP filter.
Support@Level3.com may need to be contacted to allow
in some cases. For some router vendors the peering
must be changed to an eBGP multihop session on the Level
3 side of the connection.
Please contact noc@Level3.com with any questions
regarding this functionality.
