Routing policies
- Every member of the shared VLAN should peer with all the route servers
- The route servers accept only the prefixes declared by the member
- The route servers announce all the learnt routes to any member
- Routing policies are declared in the AS20641 aut-num object defined in the RIPE database
- BGP configuration examples for peering with the route server
