Brocade Communications Systems FastIron X Series User Manual

Conguring a global IPv6 address with an automatically computed EUI-64 interface ID
To congure 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
These commands congure the global prex 2001:DB8:12d:1300::/64 and an interface ID, and enable IPv6 on Ethernet interface
1/3/1.
Syntax: ipv6 address ipv6-prex/prex-length eui-64
You must specify the ipv6-prex parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373.
You must specify the prex-length parameter as a decimal value. A slash mark (/) must follow the ipv6-prex parameter and precede the
prex-length parameter.
The eui-64 keyword congures 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’s MAC address.
Conguring a link-local IPv6 address on an interface
To explicitly enable IPv6 on a router interface without conguring a global or site-local address for the interface, enter commands such as
the following.
device(config)#interface ethernet 1/3/1
device(config-if-e1000-1/3/1)#ipv6 enable
These commands enable IPv6 on Ethernet interface 1/3/1 and specify that the interface is assigned an automatically computed link-
local address.
Syntax: [no] ipv6 enable
NOTE
When conguring 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 congured 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 congured address, enter commands
such as the following.
device(config)#interface ethernet 1/3/1
device(config-if-e1000-1/3/1)#ipv6 address FE80::240:D0FF:FE48:4672 link-local
These commands explicitly congure the link-local address FE80::240:D0FF:FE48:4672 for Ethernet interface 1/3/1.
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.
The link-local keyword indicates that the router interface should use the manually congured link-local address instead of the
automatically computed link-local address.
Conguring an IPv6 anycast address on an interface
In IPv6, an anycast address is an address for a set of interfaces belonging to
dierent nodes. Sending a packet to an anycast address
results in the delivery of the packet to the closest interface congured with the anycast address.
