BGP Route Server Proof of Concept Magnus Bergroth NORDUnet

Dynamic P2P and routers today Dynamic P2P links has two end points that normally terminates in a aggregation router at each site. On logical interface per destination site. eBGP are configured over the logical interface to each site. Reachability is advertised after the P2P link is up and BGP is established.

Drawbacks Full mesh of BGP sessions. Extensive amount of configuration. BGP sessions over short lived P2P links are most of the time down and causes alarms.

Controlplane shared with dataplane BGP over P2P P2P dynamic Site A Site B Controlplane Dataplane Controlplane shared with dataplane Dataplane reachability detected when controlplane goes down

Route server Simplify the BGP setup Only one BGP session per site Route server with one outgoing RIB per site, steering using communities General IP Route server Control plane P2P dynamic Site A Site B Dataplane Site C

draft-ietf-idr-rs-bfd-01 Edoardo found Unfortunately been quiet, and what I know no implementation ready for use. A new draft: BFD for Multipoint Networks draft-ietf-bfd-multipoint-08 lead by Juniper + Cisco  may be this will be eventually move forward

Connecting NGDF and DE-KIT via GTS Bird Route Server Connecting NGDF and DE-KIT via GTS First approach Static vlan to GTS (Géant Test system) Synchronize and deploy dynamic BGP via Route server BFD Second approach MultiNREN GTS (GTS@NORDUNet+Géant+DFN) Third approach Include transatlantic end sites (FNAL?)
