Allowed Traffic Types on Midwest-IX
The M-IX NOC reserves the right to disable ports that violate the rules below
Ethernet interfaces attached to M-IX ports must be set to auto-sensing unless otherwise agreed.
The M-IX infrastructure is based on the Ethernet II (or DIX Ethernet) standard. This means that LLC/SNAP encapsulation (802.2) is not permitted.
Frames forwarded to M-IX ports shall have one of the following ethertypes:
• 0x0800 – IPv4
• 0x0806 – ARP
• 0x86dd – IPv6
One MAC address per port
Frames forwarded to an individual M-IX port shall all have the same source MAC address.
No proxy ARP
Use of proxy ARP on the router’s interface to the Exchange is not allowed.
Frames forwarded to M-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.
No link-local traffic
Traffic for link-local protocols shall not be forwarded to M-IX ports.
Link-local protocols include, but are not limited to, the following list:
• ICMP redirects
• IEEE 802 Spanning Tree
• Vendor proprietary discovery protocols (e.g. CDP, EDP)
• Interior routing protocol broadcasts (e.g. OSPF, ISIS, IGRP, EIGRP)
• ICMPv6 ND-RA
The following link-local protocols are exceptions and are allowed:
• IPv6 ND
No directed broadcast
IP packets addressed to M-IX peering LAN’s directed broadcast address shall not be automatically forwarded to M-IX ports.
no-export of M-IX peering LAN
IP address space assigned to an M-IX peering LAN shall not be advertised to other networks without explicit permission of M-IX.
