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. For more information, refer to IPv6 neighbor discovery
configuration on page 147.
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.
device(config)#interface ethernet 1/3/1
device(config-if-e1000-1/3/1)#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 1/3/1.
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.
To configure a /122 address on a VE enter commands similar to the following.
device(config-vlan-11)#int ve11
device(config-vif-11)#ipv6 add 2001:DB8::1/122
device(config-vif-11)#sh ipv6 int

Configuring a global IPv6 address with an automatically computed EUI-64 interface ID
To configure a global IPv6 address with an automatically computed EUI-64 interface ID in the low-order 64-bits, enter commands such
as the following.
device(config)#interface ethernet 1/3/1
device(config-if-e1000-1/3/1)#ipv6 address 2001:DB8:12D:1300::/64 eui-64
