SCIX operates in cooperation with MidWest-IX and thus our connection policies are virtually identical to MidWest-IX’s policies. Those policies are duplicated here for reference:

SCIX Policies

1. This document contains a set of common rules that all networks wishing to connect to the SCIX fabric must adhere to. Failure to comply with any provision of this agreement can result in immediate disconnection from the SCIX peering fabric without notice. By connecting to the SCIX peering fabric you acknowledge that you have read, understand and agree to all the terms contained within.

2. The terms contained within this document are subject to change. By connecting to the SCIX peering fabric you agree to all future revisions. Revisions will be published and participants will be notified via e-mail 30 days in advance.3. SCIX does not manage, coordinate or act as an intermediary in relationships between connected participants and will not act as a third party in any agreement, mediation or dispute.

4. The SCIX Peering fabric may not be used in a manner that would disrupt other participant’s business or infrastructure.

5. SCIX Administration personnel reserve the right to disconnect or otherwise disrupt service to a member under any of the following conditions:

5a. Failure to follow any of the provisions of this agreement.
5b. To perform scheduled or emergency maintenance.
5c. Statutory obligation set forth by a regulating authority.
5d. As part of a request related to an ongoing investigation, warrant or subpoena issued by a recognized law enforcement entity with jurisdiction in an area in which SCIX, operates.
5e. Any unforeseen issue that would require SCIX to interrupt connectivity for the sake of its membership.

6. SCIX is not responsible for any losses incurred as a result of disruption in the continuity of the Peering fabric. The service is provided as is, without any warranties expressed or implied including merchantability or fitness for a particular purpose.

7. SCIX will schedule any maintenance a minimum of seventy-two (72) hours in advance, unless in case of an emergency.


Allowed Traffic Types on SCIX

The SCIX NOC reserves the right to disable ports that violate the rules below:

Physical Connection
Interface settings
Ethernet interfaces attached to SCIX ports must be set to auto-sensing unless otherwise agreed.

MAC Layer
Ethernet framing
The SCIX 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 SCIX ports shall have one of the following EtherTypes:
• 0x0800 – IPv4
• 0x0806 – ARP
• 0x86dd – IPv6

One MAC address per port
Frames forwarded to an individual SCIX 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.

Unicast only
Frames forwarded to SCIX ports shall not be addressed to a multicast or broadcast MAC destination address except as follows:
• broadcast ARP packets
• multicast ICMPv6 Neighbor Discovery packets.

No link-local traffic
Traffic for link-local protocols shall not be forwarded to SCIX 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)
The following link-local protocols are exceptions and are allowed:
• IPv6 ND

IP Layer
No directed broadcast
IP packets addressed to SCIX peering LAN’s directed broadcast address shall not be automatically forwarded to SCIX ports.

IP addressing
no-export of SCIX peering LAN
IP address space assigned to an SCIX peering LAN shall not be advertised to other networks without explicit permission of SCIX.

Peering Policies

1. The peering candidate must be a registered entity in its local jurisdiction.
2. The peering candidate must provide SCIX with a 24 hour contact point.
3. Only BGPv4 and BGPv6 are allowed as routing protocols.
4. The Peering candidate must have a registered, Public ASN (Autonomous System Number) issued by a recognized routing registry. (ARIN, RIPE, APNIC, LACNIC, AfriNIC)
5. SCIX only accepts peering traffic from its participants. Members may not transit charged peering traffic or use next-hop rewrites, default routes or static routes.
6. Peering parties are encouraged to aggregate routes where ever possible.
7. Only prefixes registered to the participant or for which the participant has a signed LOA on file may be announced.
8. The minimum prefix announced should be /24 for IPv4 and /48 for IPv6.
9. Members must be listed and provide updated contact information on
10. Members are expected to register their routes in a public Internet Routing Registry (IRR) database, for the purposes of filtering.

Smart City Internet Exchange Technical Requirements:
1. The only L2 frame types allowed are 0x0800, 0x86dd and 0x0806.
2. All L2/L3 protocols are forbidden with the exception of IP, NDP and ARP.
3. There is a limit of one MAC address per port. Shared cables are not permitted.
4. Ethernet aggregation is available subject to SCIX approval.
5. The use of MD5 and/or BTSH to secure BGP sessions is recommended.
