IPv6 Training (Cisco) – Setting an IPv6 Address to an Interface

Well, to make a long history short; this Interface control “ipv6 address” is used for you to assign (configure) a covering several IPv6 address to a Gresca router’s screen. At the moment, at this time there are five different methods often the “ipv6 address” control works extremely well.
View Examples Under:
Format: Router(config-if)#ipv6 address ipv6 address/prefix-length
Example: Router(config-if)#ipv6 address 2001: 100: 100: 100:: 1/64
2. Syntax: Router(config-if)#ipv6 street address ipv6 prefix/prefix-length anycast
Example of this: Router(config-if)#ipv6 address i b?rjan p? tv?tusentalet: 0DB8: 1: 1:: /64 anycast
3. Syntax: Router(config-if)#ipv6 tackle autoconfig [default]
Illustration: Router(config-if)#ipv6 address autoconfig
four. Syntax: Router(config-if)#ipv6 deal with ipv6 prefix/prefix-length eui-64
Illustration: Router(config-if)#ipv6 address 2001: 100: one hundred: 100:: /64 eui-64
five. Syntax: Router(config-if)#ipv6 deal with ipv6 link-local address/prefix-length link-local
Case in point: Router(config-if)#ipv6 address FE80:: 260: 3EFF: FE11: 5770/64 link-local
IPv6 Address Control Instances Explained:
1. Syntax: Router(config-if)#ipv6 address ipv6 address/prefix-length
Example of this: Router(config-if)#ipv6 address i b?rjan p? tv?tusentalet: one hundred: 100: 100:: 1/64
The initial example is applying the “ipv6 address” control to allocate (configure) a IPv6 International Unicast Handle (GUA) to an screen. Notice, inside the first illustration the “ipv6 address” control is needing the comprehensive IPv6 address and the prefix-length. The prefix-length (/64) is definitely articulating how many high order bits are being used for that network section of the WAR.
3. Syntax: Router(config-if)#ipv6 street address ipv6 prefix/prefix-length anycast
Instance: Router(config-if)#ipv6 address 2001: 0DB8: 1: 1:: /64 anycast
Typically the second example is getting often the “ipv6 address” command in order to assign (configure) the IPv6 Anycast Address to an program. Notice, around the second illustration often the “ipv6 address” control is only requiring the IPv6 prefix (network portion) of an IPv6 address and the particular prefix-length, followed by typically the word “anycast”.
3. Syntax: Router(config-if)#ipv6 handle autoconfig [default]
Example: Router(config-if)#ipv6 tackle autoconfig
The 3rd example will be using the “ipv6 address” command to make the particular program in question immediately autoconfigure by itself with a good IPv6 address working with stateless autoconfiguration. You can furthermore use the keyword “default” to help make the interface install a new default option. Yet keep in mind, the key phrase “default” can only be made use of on a single interface.

4. Format: Router(config-if)#ipv6 address ipv6 prefix/prefix-length eui-64
Example: Router(config-if)#ipv6 deal with i b?rjan p? tv?tusentalet: 100: 100: 100:: /64 eui-64
The fourth example is using the “ipv6 address” order to assign (configure) a IPv6 World-wide Unicast Deal with (GUA) to an interface. Yet, in contrast to the first example; this particular example is demanding that the “ipv6 address” command make use of the IPv6 prefix (network portion) of an IPv6 address as well as the prefix-length; followed by means of the expression “eui-64”. In different words, in this illustration, the interface is going to nominate (configure) the GUA to help itself; by combining typically the IPv6 prefix (network portion) which are usually the first sixty 4 (/64) high order portions; with the remaining sixty a number of low-order chunks which are the EUI-64 Screen Identifier. The EUI-64 Interface Identifier, is in fact typically the interface’s layer only two tackle (MAC Address) that is customized into EUI-64 file format.
five. Format: Router(config-if)#ipv6 tackle ipv6 link-local address/prefix-length link-local
Example of this: Router(config-if)#ipv6 address FE80:: 260: 3EFF: FE11: 5770/64 link-local
The fifth example is using the “ipv6 address” command to assign (configure) the specific (certain) layer 3 Link-Local Address to be able to the interface. Notice, that in the fifth case in point, typically the “ipv6 address” demand can be requiring the whole IPv6 link-local address plus the prefix-length, and then typically the word “link-local”. The “link-local” word is telling typically the interface, to configure (assign) the link-local address (FE80:: 260: 3EFF: FE11: 5770) to the interface in addition to also overwrite any link-local address that may have recently been configured (assigned) previously “automatically” from the interface’s MACINTOSH Address.
