remarks:
remarks:        General Info
remarks:        ==============
remarks:        GRNET donwstream customers are Greek Universities, Academic
remarks:        and Research Institutes
remarks:        GRNET has GEANT as its upstream; it also connects to GRIX
remarks:        Internet Exchange
remarks:
remarks:        RPKI in GRNET
remarks:        ==============
remarks:        GRNET ***drops*** ALL RPKI invalid prefixes received from Upstream
remarks:        and Greek Internet Exchange (GR-IX)
remarks:
remarks:        PA Space Aggregation
remarks:        =============
remarks:        GRNET aggregates its PA space before announcing it to its
remarks:        upstream(s) and exchanges. Should a customer with PA space
remarks:        wishes not to have its prefixes aggregated, a special community
remarks:        should be used to tag this route (see below).
remarks:        Prefixes from GRNET allocation that announced from public ASs
remarks:        are announced deaggregated.\
remarks:        Prefix lengths longer than /24 for IPv4 and /48 for IPv6 are NOT
remarks:        announced to Upstream or GRIX
remarks:
remarks:        Primary/Backup control
remarks:        ========================
remarks:        GRNET respects the MED received by its customers; thus, the
remarks:        customers can indicate their primary/backup line and control
remarks:        incoming traffic by setting MED appropriatelly. Also, the
remarks:        customers may use the community 5408:110 to indicate their
remarks:        backup connection (lower local pref), but this method is
remarks:        recommended only for customers multihomed to another Greek ISP
remarks:        that use their connection with GRNET as backup.
remarks:
remarks:        Hot Potato routing
remarks:        ========================
remarks:        By setting the same attributes (Local Preference and MED) on
remarks:        advertising prefixes, a customer with more than one connections
remarks:        with GRNET has the ability to use all active paths.
remarks:        By this way, "hot potato" routing is achieved. Traffic will exit
remarks:        GRNETs network choosing the closest to destination border router.
remarks:
remarks:        Anycast
remarks:        ========================
remarks:        GRNET does not follow any explicit policy for anycast services.
remarks:        Normal routing (and, thus, preference) applies to all anycast
remarks:        routes
