CENTRALIZED MODE FOR IPV6
Centralization is used when an IPv4 hardware module needs to forward IPv6
traffic. This accomplished through the use of Link Aggregation service ports,
which creates a loopback group, on an IPv6 hardware ready module. When
configuring centralization refer to the following sections:
■ “Centralized Mode for IPv6 Multicast and IPv6 Unicast” on page 709
■ “Configuring Centralized Mode for IPv6 Multicast and IPv6 Unicast” on page
709
■ “Configuring IPv6 Multicast and IPv6 Unicast Centralized Mode Example” on
page 710

Before configuring Centralized Mode for IPv6 multicast, make sure that at least
one IPv6-capable module is installed in the device.
Centralized Mode for
IPv6 Multicast and
IPv6 Unicast
Centralized Mode for IPv6 traffic is designed to make IPv6 multicast and IPv6
unicast possible on modules that do not have the hardware support for IPv6.
Currently, for Switch 8800s, only IPv6-capable modules support IPv6 traffic. In
practice, however, a Switch 8800 may comprise different types of modules. If you
need to forward IPv6 traffic on a non-IPv6 module, you can configure an IPv6
module to forward that traffic by using Link Aggregation service ports.
Service loops are specialized link aggregation groups, which will automatically
re-direct IPv6 traffic from a non IPv6-capable module to the loopback port of an
IPv6-cpable module.

Prerequisites
Before configuring Centralized Mode for IPv6 multicast or IPv6 unicast traffic,
make sure that at least one IPv6 module is installed on your Switch 8800.
