Site | Routing policies |
---|---|
CA-TRIUMF | We accept only the LHC-OPN routes from the CH-CERN over the one and five Gbit/s light paths to CERN. On the peering with the US-T1-BNL we accept the US-T1-BNL prefixes related to the ATLAS and also accepting the LHC-OPN routes from the CH-CERN. On peering with the NL-T1 we accept prefixes from SARA. |
DE-KIT | All prefixes within the LHCOPN (T0 & T1s) are accepted To exchange data with T0 the direct link LHCOPN to CH-CERN is prefered. The backup link is LHCONE and General Purpose Internet (GPI). For Tier-1 to Tier-1 traffic to ○ FR-CCIN2P3, ○ IT-INFN-CNAF; ○ FNAL LHCONE is prefered All other T1s traffic is preferably carried through LHCOPN (CH-CERN) The last resort "Internet backup" is allowed to carry any LHCOPN prefixes (T0 & T1s). |
ES-PIC | All prefixes within the LHCOPN (T0 & T1s) in the BGP peering of the 10GE link are accepted by our Cisco6500. To exchange with T0 we use primary 10GE direct link to CH-CERN. There's also a 1GE PIC-CERN link where all CERN prefixes are accepted and whole PIC is announced via BGP in a 10GE Nokia-Checkpoint firewall; this link is used as backup for the T0 when the primary 10GE link is not available. The Internet is used as secondary backup option for the T0 and primary backup for T1s traffic, the Internet BGP peering takes place at the Nokia-Checkpoint firewall too. |
FR-CCIN2P3 | We accept all prefixes within the LHCOPN (T0 & T1s) and we re-annouce prefixes from CH-CERN and DE-KIT. To exchange with T0 we use direct link to CH-CERN, backup is through DE-KIT. To exchange with T1s: - Traffic with DE-KIT, NL-T1 and IT-INFN-CNAF is by default using T1-T1 link GRIDKA-IN2P3-LHCOPN-001 - For all other T1s traffic is going through CH-CERN , but all prefixes are allowed through DE-KIT in case of primary link failure. Our last resort internet backup is allowed to carry any LHCOPN prefixes (T0 & T1s). |
NL-T1 | NL-T1 is peering with: - CH-CERN (AS513, via direct T0-T1 link, 10Gbit/s) - NDGF (AS30590, via direct T1-T1 link, 10 Gbit/s) - DE-KIT (AS34878, via direct T1-T1 link, 10 Gbit/s) - TW-ASGC (AS24167,via direct T1-T1 link, 2x1 Gbit/s) - CA-Triumf (AS36391, via direct T1-T1link, 1 Gbit/s) - US-FNAL-CMS (AS3152, via direct T1-T1link, 1 Gbit/s) - Nikhef (AS1104, direct internal NL-T1 link, 10 Gbit/s) On the peering with CH-CERN we accept everyting and announce everyting except prefixes we receive directly from TW-ASGC, CA-TRIUMF and US-FNAL-CMS (all via direct T1-T1 links), however we do announce any backup route to those sites. This based on route leaking between different VRF's On the peering with NDGF we accept everyting and announce everyting except prefixes we receive directly from TW-ASGC, CA-TRIUMF, US-FNAL-CMS (all via direct T1-T1 links) and IT-INFN-CNAF (via DE-KIT), however we do announce any backup route to those sites. This is based on a combination of route leaking between different VRF's and AS-PATH filtering On the peering with DE-KIT we accept everyting and announce everyting except prefixes we receive directly from TW-ASGC and CA-TRIUMF (all via direct T1-T1 links), however we do announce any backup route to those sites, in addition we do announce US-FNAL prefixes. This is based on route leaking between different VRF's On the peering with TW-ASGC we accept TW-ASGC prefixes (AS-PATH filtering) and announce NL-T1 prefixes (prefix filtering) On the peering with US-FNAL-CMS we accept US-FNAL-CMS prefixes (AS-PATH filtering) and announce NL-T1 (prefix filtering) and DE-KIT prefixes (AS-PATH filtering) On the peering with CA-TRIUMF we accept CA-TRIUMF prefixes (AS-PATH filtering) and announce NL-T1 prefixes (prefix filtering). On the peering with Nikhef we accept Nikhef prefixes (AS-PATH filtering) and announce all LHCOPN prefixes except the NL-T1 perfSONAR prefix. AS-PATH filtering means: accepting prefixes which begin with AS# of peer (prepending possible). Prefix filtering means: prefix filter for prefixes advertised to peer. |
UK-T1-RAL | General packet filtering is in place outbound on the border router. Any LHCOPN monitoring is able to look inwards to the LHCOPN, i.e. in the direction of CERN, but not into the RAL site network. |
US-FNAL-CMS | PBR inbound/outbound between USCMS FNAL subnets and accepted LHCOPN prefixes. Acceptance of prefixes across LHCOPN by agreement - USCMS FNAL prefixes filtered using the LHCOPN BGP communities. Prefixes accepted and USCMS FNAL prefixes advertised across direct peerings by agreement. |
RRC-KI-T1 | Currently we receive and accept all announcements via CERN for AS 43, 137, 513, 789, 1162, 17579, 24167, 34878, 36391, 39590, 43115, 43475, 61339. Our routes aren't reannounced from CERN to FNAL, since we have no response from this Tier-1 yet. All new Tier-1 sites are kindly requested to announce community 513:59624 (do not announce to AS 59624) to CERN until we will tune our ACLs to accept and announce our prefixes towards new Tier-1 centres to facilitate symmetric routing. Notice for new peerings at noc@computingNOSPAMPLEASE.kiae.ru will be much appreciated. |
