BCP for IXPs - PoPs • Neutral coloca+on (ideally datacenters) for PoPs • Layer-‐2 infrastructure (either na+ve Ethernet or VPLS based)
• Resiliency and scalability : – Equipment redundancy or spare equipment for PoPs
– When mul+-‐PoPs architecture : edge PoPs & core PoPs vs full-‐mesh design
– Use of passive WDM for PoPs interconnec+ons (when appropriate and possible)

BCP for IXPs – Technical requirements
• Provide na+ve layer-‐2 (or fully transparent layer-‐2 infrastructure)
• Block spanning-‐tree on all members ports • Allow only authorized EtherTypes (IPv4, IPv6, ARP) • Limit MAC learning (one MAC/port) and apply MAC filtering • Use storm control (broadcast/mul+cast) or apply rate-‐limi+ng
filters to limit broadcast • Allow LACP • Quaran+ne VLAN (mainly for new members) => Don’t connect a new member on the IXP without running a strict valida+on procedure
