Configuring basic IPv6 connectivity on a Layer 3 switch
To configure IPv6 address on an interface with an automatically computed EUI-64 interface ID in
the low-order 64-bits on devices running a router image, enter commands such as the following.
TurboIron(config)#interface ethernet 1
TurboIron(config-if-e10000-1)#ipv6 address 2001:DB8:12D:1300::/64 eui-64
These commands configure the global prefix 2001:DB8:12d:1300::/64 and an interface ID, and
enable IPv6 on Ethernet interface 1.
Syntax: ipv6 address
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.
The eui-64 keyword configures the global 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 MAC
address.
Configuring a link-local IPv6 address on an interface
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.
TurboIron(config)#interface ethernet 1
TurboIron(config-if-e10000-1)#ipv6 enable
These commands enable IPv6 on Ethernet interface 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 physical or 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 physical and VE interfaces is derived from a
global MAC address, all physical and 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.
TurboIron(config)#interface ethernet 1
TurboIron(config-if-e10000-1)#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 1.
Syntax: ipv6 address <ipv6-address> link-local
You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons
as documented in RFC 2373.
The link-local keyword indicates that the router interface should use the manually configured
link-local address instead of the automatically computed link-local address.
