IPv6 Deployment in Internet Exchange Points (IXPs)
Abstract
This document provides guidance on IPv6 deployment in Internet
Exchange Points (IXPs). It includes information regarding the switch
fabric configuration, the addressing plan and general organizational
tasks that need to be performed. IXPs are mainly a Layer 2
infrastructure, and, in many cases, the best recommendations suggest
that the IPv6 data, control, and management plane should not be
handled differently than in IPv4.

1. Introduction
Most Internet Exchange Points (IXPs) work at the Layer 2 level,
making the adoption of IPv6 an easy task. However, IXPs normally
implement additional services such as statistics, route servers,
looking glasses, and broadcast controls that may be impacted by the
implementation of IPv6. This document clarifies the impact of IPv6
on a new or an existing IXP. The document assumes an Ethernet switch
fabric, although other Layer 2 configurations could be deployed.
2. Switch Fabric Configuration
An Ethernet-based IXP switch fabric implements IPv6 over Ethernet as
described in [RFC2464] . Therefore, the switching of IPv6 traffic
happens in the same way as in IPv4. However, some management
functions (such as switch management, SNMP (Simple Network Management
Protocol) [RFC3411] support, or flow analysis exportation) may
require IPv6 as an underlying layer, and this should be assessed by
the IXP operator.
There are two common configurations of IXP switch ports to support
IPv6:
1. dual-stack LAN (Local Area Network): when both IPv4 and IPv6
traffic share a common LAN. No extra configuration is required
in the switch.
2. independent VLAN (Virtual Local Area Network)[IEEE.P802-1Q.1998]:
when an IXP logically separates IPv4 and IPv6 traffic in
different VLANs.

In both configurations, IPv6 and IPv4 traffic can either share a
common physical port or use independent physical ports. The use of
