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: PA Space Aggregation
remarks: =============
remarks: GRNET aggregates its PA space before announcing it to its
remarks: upstream(s) and exchanges. Should a custemer with PA space
remarks: wishes not to have its prefexes aggregated, a special community
remarks: should be used to tag this route (see below).
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: Anycast
remarks: ========================
remarks: GRNET does not follow any explicit policy for anycast services.
