Configuring IPv6 on each router interface

• 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.
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
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.
• 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. For more information,
refer to “Configuring IPv6 neighbor discovery” on page 1096.
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.
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ipv6 address 2001:200:12D:1300:240:D0FF:
FE48:4672/64
These commands configure the global prefix 2001:200:12d:1300::/64 and the interface ID
::240:D0FF:FE48:4672, and enable IPv6 on Ethernet interface 3/1.
Syntax: ipv6 address <ipv6-prefix>/<prefix-length>
You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons
as documented in RFC 2373.
You must specify the <prefix-length> parameter as a decimal value. A slash mark (/) must follow
the <ipv6-prefix> parameter and precede the <prefix-length> parameter.
