The link-local keyword indicates that the router interface should use the manually congured link-local address instead of the
automatically computed link-local address.
Conguring the management port for an IPv6
automatic address conguration
You can have the management port congured to automatically obtain an IPv6 address. This process is the same for any other port and
is described in detail in the section Conguring a global or site-local IPv6 address on an interface on page 159
Conguring basic IPv6 connectivity on a Layer 3
switch
To congure basic IPv6 connectivity on a Brocade Layer 3 Switch, you must do the following:
• Enable IPv6 routing globally on the switch
• Congure an IPv6 address or explicitly enable IPv6 on each router interface over which you plan to forward IPv6 trac
• Congure IPv4 and IPv6 protocol stacks. (This step is mandatory only if you want a router interface to send and receive both
IPv4 and IPv6 trac.)
All other conguration tasks in this chapter are optional.
Enabling IPv6 routing
By default, IPv6 routing is disabled. To enable the forwarding of IPv6
trac globally on the Layer 3 switch, enter the following command.
device(config)#ipv6 unicast-routing
Syntax: [no] ipv6 unicast-routing
To disable the forwarding of IPv6 trac globally on the Brocade device, enter the no form of this command.
IPv6 conguration on each router interface
To forward IPv6 trac on a router interface, the interface must have an IPv6 address, or IPv6 must be explicitly enabled. By default, an
IPv6 address is not congured on a router interface.
If you choose to congure a global or site-local IPv6 address for an interface, IPv6 is also enabled on the interface. Further, when you
congure a global or site-local IPv6 address, you must decide on one of the following in the low-order 64 bits:
• A manually congured 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 congured link-local address with
an address that you manually congure.
This section provides the following information:
• Conguring a global or site-local address with a manually congured or automatically computed interface ID for an interface.
