Configuring IPv6 on each router interface
44
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 1183.
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.
Configuring a global or site-local IPv6 address with an automatically computed
EUI-64 interface ID
To configure a global or site-local IPv6 address with an automatically computed EUI-64 interface ID
in the low-order 64-bits, 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::/64 eui-64
These commands configure the global prefix 2001:200:12d:1300::/64 and an interface ID, and
enable IPv6 on Ethernet interface 3/1.
Syntax: ipv6 address <ipv6-prefix>/<prefix-length> eui-64
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.
The eui-64 keyword configures the global or site-local address with an EUI-64 interface ID in the
low-order 64 bits. The interface ID is automatically constructed in IEEE EUI-64 format using the
interface’s MAC address.
