1.1 Interface settings

100base and 10base Ethernet interfaces attached to AMS-IX ports must be explicitly configured with speed, duplex other configuration settings, i.e. they should not be auto-sensing.

2.1 Ethernet framing

The AMS-IX infrastructure is based on the Ethernet II (or “DIX Ethernet”) standard. This means that LLC/SNAP encapsulation (802.2) is not permitted. For more information on the differences, see the Ethernet FAQ, question 4.1.

2.2 Ethertypes

Frames forwarded to AMS-IX ports must have one of the following ethertypes:

• 0x0800 - IPv4
• 0x0806 - ARP
• 0x86dd - IPv6

2.3 One MAC address per port

Frames forwarded to an individual AMS-IX port shall all have the same source MAC address.

2.4 No proxy ARP

Use of proxy ARP on the router's interface to the Exchange is not allowed.

2.5 Unicast only

Frames forwarded to AMS-IX ports shall not be addressed to a multicast or broadcast MAC destination address except as follows:

• broadcast ARP packets
• multicast ICMPv6 Neighbour Discovery packets. Please note that this DOES NOT include Router Discovery packets

2.6 No link-local traffic

Traffic for link-local protocols shall not be forwarded to AMS-IX ports.

Link-local protocols include, but are not limited to, the following list:

• IRDP
• ICMP redirects
• IEEE 802 Spanning Tree
• Vendor proprietary protocols. These include, but are not limited to:
  • Discovery protocols: CDP, EDP
  • VLAN/trunking protocols: VTP, DTP
• Interior routing protocol broadcasts (e.g. OSPF, ISIS, IGRP, EIGRP)
• BOOTP/DHCP
• PIM-SM
• PIM-DM
• DVMRP
• ICMPv6 ND-RA
• UDLD
• L2 Keepalives

The following link-local protocols are exceptions and are allowed:

• ARP
• IPv6 ND

3.1 No directed broadcast

IP packets addressed to AMS-IX peering LAN's directed broadcast address shall not be automatically forwarded to AMS-IX ports.

4.1 no-export of AMS-IX peering LAN

IP address space assigned to AMS-IX peering LAN shall not be advertised to other networks without explicit permission of AMS-IX.
