Allowed Traffic Types on Unicast Peering LANs
To ensure smooth operation of the ECIX infrastructure, we impose a set of restrictions. These govern the kind of traffic allowed on the peering fabric. This page gives a summary of those restrictions. For more information, including advice on equipment configuration, please see the ECIX Configuration Guide.
1. Physical Connection
1.1 Interface settings
1000BASE Ethernet interfaces attached to ECIX ports should be explicitly configured with speed and duplex settings. They should not be auto-sensing.
2. MAC Layer
2.1 Ethernet framing
The ECIX 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 Ethernet types
Frames forwarded to ECIX ports must have one of the following ethertypes:
- 0x0800 - IPv4
- 0x0806 - ARP
- 0x86dd - IPv6
2.3 One MAC address per port per VLAN
Frames forwarded to an individual ECIX 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 Internet Exchange is not allowed.
2.5 Unicast only
Frames forwarded to ECIX 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 Solicitation or Advertisement packets
2.6 No link-local traffic
Traffic for link-local protocols shall not be forwarded to ECIX ports.
Link-local protocols include, but are not limited to, the following list:
- 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)
- ICMPv6 ND-RA
- L2 Keepalives
The following link-local protocols are exceptions and are allowed:
- IPv6 ND
3. IP Layer
3.1 No directed broadcast
IP packets addressed to ECIX peering LAN's directed broadcast address shall not be automatically forwarded to ECIX ports.
4. IP addressing
4.1 no-export of ECIX peering LAN
IP address space assigned to ECIX Peering LANs shall not be advertised to other networks without explicit permission of ECIX.
