remarks: of information technology and telecommunications.

remarks: with other Greek major networks and members of GR-IX.
remarks:

remarks: security policy according to Greek/EU laws. We are also
remarks: a RIPE member since 2000 and we operate as a LIR.
remarks:
remarks: We use the RIPE database as the primary IRR database
remarks: in which we register most of our objects.
remarks:
remarks: The as-set which contains our own AS number and all our
remarks: customers' AS numbers is AS-DATAWAYS. Please use this
remarks: as-set if you do prefix filtering, unless otherwise noted.
remarks:

remarks:
remarks: General Peering Policy Info
remarks: ===========================
remarks:
remarks: - We honor no-export and no-advertise well-known
remarks: communities.
remarks:
remarks: - We do *NOT* honor the MED BGP attribute. All routes
remarks: received from our upstreams, customers or IX-peers on both
remarks: primary/backup routers get a metric of 0. Please see below
remarks: about our primary/backup scheme.
remarks:
remarks: - bogon/martian prefixes are rejected on import.
remarks:
remarks: - Prefixes containing a bogon/reserved/private AS number
remarks: in their as-path are rejected.
remarks:
remarks: - We reject the default-route prefix (0/0, ::/0) from all
remarks: peers (upstreams/customers/IX-peers).
remarks:
remarks: - Prefixes longer than /24 for IPv4 or /48 for IPv6
remarks: are rejected.
remarks:
remarks: - We use BOTH prefix access lists and as-path access lists
remarks: for prefix filtering. Customers or IX-peers imported
remarks: prefixes must be registered with a valid route/route6
remarks: object in the RIPE database. The prefix must be originating
remarks: from the customer's AS or, in case the peer is an IX-peer,
remarks: the peer's AS and their adjacent AS if any.
remarks:
remarks: All other advertisements are rejected.
remarks:
remarks: Our filters are automatically updated every business-day
remarks: morning. Contact noc@dataways.gr for an irregular update.
remarks:
remarks:
remarks: Primary/Backup BGP Routers
remarks: ==========================
remarks: DATAWAYS prefers to connect with other autonomous systems
remarks: using a cluster of bgp routers with at least two BGP
remarks: sessions for redundancy. Each session originates from a
remarks: different router. The first/primary session is maintained
remarks: on our primary-designated router while any other secondary
remarks: sessions use our backup(s) router(s).
remarks:
remarks: Routes received from our peers on the primary router always
remarks: get a higher local preference than the backup router.
remarks:
remarks: Our customers can fine-tune our local-preference values
remarks: using the appropriate community tags. See below.
remarks:
remarks: Routes advertised to our peers have their metric set to 0
remarks: on primary and 20 on backup. If the remote AS does not
remarks: honor the MED attribute we follow the appropriate
remarks: technique as instructed by the remote AS import policy.
remarks:
remarks:
remarks: BGP Communities used by our Customers
remarks: =====================================
remarks: Our customers can use the following communities to
remarks: influence our BGP routers:
remarks:
remarks: as-path prepend:
remarks: ----------------

remarks:
remarks: local-preference override:
remarks: --------------------------

remarks: to very-low local-preference mode.
remarks:
remarks: In normal operations the customer's announcements have
remarks: a higher local-preference value than IX-peers and
remarks: upstreams announcements.
remarks:
remarks: The order is: [CUSTOMER] > [IX-PEERS] > [UPSTREAMS]
remarks:
remarks: If you tag your advertisements with 15544:7090 then
remarks: the order changes to:
remarks:
remarks: [IX-PEERS] > [UPSTREAMS] > [CUSTOMER]
remarks:
remarks: In this mode, prefixes received from IX-peers and/or

remarks: backup/last resort path.
