Configuring the management port for an IPv6 automatic address configuration
You can have the management port configured to automatically obtain an IPv6 address. This
process is the same for any other port and is described in detail in the section “Configuring a global
IPv6 address with an automatically computed EUI-64 interface ID” on page110
Configuring basic IPv6 connectivity ona Layer 3 switch
To configure basic IPv6 connectivity on a Brocade Layer 3 Switch, you must do the following:
•Enable IPv6 routing globally on the switch
•Configure an IPv6 address or explicitly enable IPv6 on each router interface over which you
plan to forward IPv6 traffic
•Configure IPv4 and IPv6 protocol stacks. (This step is mandatory only if you want a router
interface to send and receive both IPv4 and IPv6 traffic.)
All other configuration tasks in this chapter are optional.

Enabling IPv6 routing

By default, IPv6 routing is disabled. To enable the forwarding of IPv6 traffic globally on the Layer 3
switch, enter the following command.
Brocade(config)#ipv6 unicast-routing
Syntax: [no] ipv6 unicast-routing
To disable the forwarding of IPv6 traffic globally on the Brocade device, enter the no form of this
command.

IPv6 configuration on each router interface

To forward IPv6 traffic on a router interface, the interface must have an IPv6 address, or IPv6 must
be explicitly enabled. By default, an IPv6 address is not configured on a router interface.
If you choose to configure a global or site-local IPv6 address for an interface, IPv6 is also enabled
on the interface. Further, when you configure a global or site-local IPv6 address, you must decide
on one of the following in the low-order 64 bits:
•A manually configured interface ID.
•An automatically computed EUI-64 interface ID.
If you prefer to assign a link-local IPv6 address to the interface, you must explicitly enable IPv6 on
the interface, which causes a link-local address to be automatically computed for the interface. If
preferred, you can override the automatically configured link-local address with an address that you
manually configure.
