GEANT Upstream and Peering Service The GEANT Network Connects the European National Regional Education Networks (NRENs) together We are on peeringdb.com @ https://www.peeringdb.com/net/3386 === BEGIN === INFORMATION ========================================================== NRENs are configured with either the opt-in or the opt-out model at the time of joining. NRENs may switch at any time (contact GEANT Ops), Opt-out model - GEANT tags NREN routes for announcement to all providers, and NRENs block to all or specific providers as required. Opt-in model - NRENs tag routes for selective announcement to all or specific providers, and block communities take precedence over announce communities. *** BEGIN *** BGP Communities *** INFORMATIONAL - Routes we learn are tagged as follows: 21320:XXXyy, where XXX denotes our relationship to the BGP speaker 21320:xxxYY, where YY denotes the location at which we learned the route Relationship :- 21320:645yy Upstream/Tier 1 transit 21320:646yy Public peer via Internet Exchange fabric 21320:647yy Private peer via dedicated interconnect 21320:648yy Research & Education peers 21320:649yy NREN peers, i.e. GEANT consortium members Location :- ( Geographic and Internet Exchange where applicable ) Geographic (POP_ID/AREA_ID) 21320:xxx09 Iberian Ring (POR,BIL,MAD,LIS) 21320:xxx12 Omnipresent, i.e. injected, generated, static routes 21320:xxx13 Amsterdam NL (AMS) 21320:xxx14 Athens GR (ATH/ATH2) 21320:xxx15 Bratislava SK (BRA) 21320:xxx16 Brussels BE (BRU) 21320:xxx17 Bucharest RO (BUC) 21320:xxx18 Budapest HU (BUD) 21320:xxx20 Dublin IE (DUB) 21320:xxx22 Frankfurt DE (FRA) 21320:xxx23 Geneva CH (GEN) 21320:xxx24 Hamburg DE (HAM) 21320:xxx25 Kaunas LT (KAU) 21320:xxx26 Lisbon PT (LIS) 21320:xxx27 Ljubljana SI (LJU) 21320:xxx28 London UK (LON) 21320:xxx30 Madrid ES (MAD) 21320:xxx31 Marseilles FR (MAR) 21320:xxx32 Milan Lancetti IT (MIL) 21320:xxx33 Milan Caldera IT (MIL2) 21320:xxx35 Paris FR (PAR) 21320:xxx36 Poznan PL (POZ) 21320:xxx37 Prague CZ (PRA) 21320:xxx38 Riga LV (RIG) 21320:xxx39 Sofia BG (SOF) 21320:xxx41 Vienna AT (VIE) 21320:xxx42 Zagreb AT (ZAG) 21320:xxx43 London 2 UK (LON2) 21320:xxx44 Porto PT (POR) 21320:xxx45 Chisinau MD (CHI) 21320:xxx46 Kiev UA (KIE) 21320:xxx47 Bilbao ES (BIL) 21320:xxx48 Cork IE (COR) 21320:xxx49 Tartu EE (TAR) 21320:xxx50 Thessaloniki GR (THE) 21320:xxx51 RESERVED 21320:xxx52 Budapest 2 (BUD2) 21320:xxx53 Geneva 2 (GEN2) 21320:xxx54 Belgrade (BEL) 21320:xxx55 RESERVED 21320:xxx56 Luxembourg (LUX) 21320:xxx57 Stockholm (STO) Internet Exchanges (IX_ID) 21320:xxx80 Helsinki FICEX 21320:xxx81 Poznan PL DE-CIX 21320:xxx82 Lisbon GigaPIX 21320:xxx83 Athens GR-IX 21320:xxx84 Brussels BNIX 21320:xxx85 Luxembourg LU-CIX 21320:xxx86 Sofia BIX.BG 21320:xxx87 Ljubljana SI SIX 21320:xxx88 Budapest HU BiX 21320:xxx89 Madrid ES DE-CIX Madrid 21320:xxx90 Marseilles FR DE-CIX Marseilles 21320:xxx91 Prague CZ NIX.CZ 21320:xxx92 <virtual> -- NORDUnet peering aggregation 21320:xxx93 Dublin IE INEX LAN1 21320:xxx94 Geneva CH CIXP 21320:xxx95 Milan IT MIT-IT 21320:xxx96 London UK LINX Juniper LAN 21320:xxx97 Vienna AT VIX 21320:xxx98 Frankfurt DE DE-CIX Frankfurt 21320:xxx99 Amsterdam NL AMS-IX *** BEGIN *** LEGACY BGP Communities - Informational *** GEANT Tags routes as follows: 20965:0003 GEANT IAS Peering Service peers, public (IX) only. 20965:0004 GEANT IAS Peering Service peers, public (IX) and private. 20965:15169 - All routes received from Google 20965:7777 - All routes received from the commodity providers *** END *** LEGACY BGP Communities - Informational *** TRAFFIC ENGINEERING - NRENs may engineer (re-)announcements as follows: Announce :- 64700:<ASN> - Announce toward <ASN> everywhere 64700:65532 - Announce toward all public peers 64700:65533 - Announce toward all private peers 64700:65534 - Announce toward all upstreams Prepend :- You must use two communities at a minimum.
