1. BGP Route Server Proof of Concept
Magnus Bergroth
NORDUnet

2. 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.

3. 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.

4. Controlplane shared with dataplane

5. Route server Simplify the BGP setup Only one BGP session per site
Route server with one outgoing RIB per site, steering using communities

6. 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

7. 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
Third approach
Include transatlantic end sites (FNAL?)
