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.
Configuring a link-local IPv6 address
To explicitly enable IPv6 on a router interface without configuring a global or site-local address for
the interface, enter commands such as the following.
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ipv6 enable
These commands enable IPv6 on Ethernet interface 3/1 and specify that the interface is assigned
an automatically computed link-local address.
Syntax: [no] ipv6 enable
NOTE
When configuring VLANs that share a common tagged interface with a Virtual Ethernet (VE)
interface, Brocade recommends that you override the automatically computed link-local address
with a manually configured unique address for the interface. If the interface uses the automatically
computed address, which in the case of VE interfaces is derived from a global MAC address, all VE
interfaces will have the same MAC address.
To override a link-local address that is automatically computed for an interface with a manually
configured address, enter commands such as the following.
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ipv6 address FE80::240:D0FF:FE48:4672 link-local
These commands explicitly configure the link-local address FE80::240:D0FF:FE48:4672 for
Ethernet interface 3/1.
Syntax: ipv6 address <ipv6-address> link-local
You must specify the <ipv6-address> parameter in hexadecimal using 16-bit values between
colons as documented in RFC 2373.
