Configuring basic IPv6 connectivity on a Layer 3 switch
•
An automatically computed EUI-64 interface ID on router image.
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.
This section provides the following information:
•
Configuring a global or site-local address with a manually configured or automatically
computed interface ID for an interface.
•
Automatically or manually configuring a link-local address for an interface.
•
Configuring IPv6 anycast addresses
Configuring a global or site-local IPv6 address on an interface
Configuring a global or site-local IPv6 address on an interface does the following:
•
Automatically configures an interface ID (a link-local address), if specified.
•
Enables IPv6 on that interface.
Additionally, the configured interface automatically joins the following required multicast groups for
that link:
•
Solicited-node multicast group FF02:0:0:0:0:1:FF00::/104 for each unicast address assigned
to the interface.
•
Solicited-node for subnet anycast address for each unicast assigned address
•
Solicited-node for anycast address FF02:0:0:0:0:1:FF00::0000
•
All-nodes link-local multicast group FF02::1
•
All-routers link-local multicast group FF02::2
The neighbor discovery feature sends messages to these multicast groups.
Configuring a global or site-local IPv6 address with a manually configured interface ID
To configure a global or site-local IPv6 address, including a manually configured interface ID, for an
interface, enter commands such as the following.
TurboIron(config)#interface ethernet 1
TurboIron(config-if-e10000-1)#ipv6 address 2001:DB8:12D:1300:240:D0FF:
FE48:4672:/64
These commands configure the global prefix 2001:DB8:12d:1300::/64 and the interface ID
::240:D0FF:FE48:4672, and enable IPv6 on Ethernet interface 1.
Syntax: ipv6 address <ipv6-prefix> /
You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons
as documented in RFC 2373.
You must specify the
the <ipv6-prefix> parameter and precede the <prefix-length> parameter.

NOTE
This is supported on devices running router image.
