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
