These Technical requirements (TR) define the ways in which you may or may not make use of the SEECIX services. This document will be regularly reviewed and revised in the light of operational experience to ensure maximum protection of service to SEECIX members. Subsequent versions of this document are effective after 10 working days of having been posted upon SEECIX website.
Members' use of the SEECIX network shall at all times conform to the relevant standards as laid out in STD0001 and associated Internet STD documents.
Ethernet interfaces attached to SEECIX ports shall be explicitly configured with duplex, speed and other configuration settings and shall not be auto-sensing.
2. MAC Layer
2.1 Frames forwarded to SEECIX ports shall have one of the following ethertypes
- 0x0800 - IPv4
- 0x0806 - ARP
- 0x86dd - IPv6
2.2 All frames of a service forwarded to an individual SEECIX port shall have the same source MAC address.
2.3 Frames forwarded to SEECIX ports shall not be addressed to a multicast or broadcast MAC destination address except as follows:
- broadcast ARP packets
- multicast IPv6 Neighbour Discovery (ND) packets
- if explicitly allowed for that port (e.g. multicast service)
2.4 Traffic for link-local protocols shall not be forwarded to SEECIX ports except for the following:
- ARP except proxy ARP
- IPv6 ND
These link-local protocols include but are not limited to the following list:
- ICMP redirects
- IEEE802 Spanning Tree
- Vendor proprietary discovery protocols (e.g. CDP)
- Interior routing protocol broad/multicasts (e.g. OSPF, IS-IS, IGRP, EIGRP)
2.5 ARP traffic shall not exceed 20 pps per port/vlan.
2.6 Standard Ethernet MTU size = 1554
3. IP Layer
3.1 Interfaces connected to SEECIX ports shall only use IP addresses and netmasks (prefix lengths) assigned to them by SEECIX. In particular:
- IPv6 addresses (link & global scope) shall be explicitly configured and not auto-configured
- IPv6 site-local addresses shall not be used
3.2 IP packets addressed to SEECIX peering LAN directed broadcast address shall not be automatically forwarded to SEECIX ports.
3.3 Standard IP MTU size = 1500
4.1 All exchange of routes across the SEECIX network shall be via BGP4(+).
4.2 AS numbers used in BGP4(+) sessions across the SEECIX network shall not be from range reserved for private use.
4.3 All routes advertised shall be aggregated as far as possible.
4.4 IP address space assigned to SEECIX peering LAN shall not be advertised to other networks without explicit permission of SEECIX. All routes advertised across the SEECIX network shall point to the router advertising it unless an agreement has been made in advance in writing by SEECIX and the members involved. All routes to be advertised in a peering session across SEECIX shall be registered in the RIPE or other public routing registry. Members may use more than one ASN for their SEECIX peering provided that each ASN presented shares the same NOC and peering contact details.
5.1 Traffic shall only be forwarded to a SEECIX member when permission has been given by the receiving member either:
- by advertising a route across the SEECIX network (directly or via the routeserver)
- or explicitly in writing
5.2 Traffic shall not be routinely exchanged between two SEECIX ports owned by the same SEECIX member.
