remarks: # ROUTING POLICY FOR GRNET AS5408)
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
