IPv6 Teaching (Cisco) – Assigning an IPv6 Tackle to an Interface

Effectively, to create a lengthy story small; the Interface command “ipv6 address” is utilized to assign (configure) a layer three IPv6 handle to some Cisco router’s interface. Currently, you can find 5 alternative ways the “ipv6 address” command may be used.

Look at Illustrations Underneath:

Syntax: Router(config-if)#ipv6 deal with ipv6 deal with/prefix-length
Instance: Router(config-if)#ipv6 address 2001:one hundred:100:one hundred::1/64
2. Syntax: Router(config-if)#ipv6 deal with ipv6 prefix/prefix-duration anycast

Example: Router(config-if)#ipv6 tackle 2001:0DB8:1:1::/64 anycast

three. Syntax: Router(config-if)#ipv6 deal with autoconfig [default]

Instance: Router(config-if)#ipv6 address autoconfig

four. Syntax: Router(config-if)#ipv6 tackle spf flattening ipv6 prefix/prefix-duration eui-sixty four

Illustration: Router(config-if)#ipv6 address 2001:one hundred:a hundred:a hundred::/sixty four eui-sixty four

5. Syntax: Router(config-if)#ipv6 tackle ipv6 link-local address/prefix-duration connection-regional

Example: Router(config-if)#ipv6 handle FE80::260:3EFF:FE11:5770/sixty four link-area

IPv6 Address Command Illustrations Explained:

1. Syntax: Router(config-if)#ipv6 deal with ipv6 tackle/prefix-size

Illustration: Router(config-if)#ipv6 tackle 2001:one hundred:100:a hundred::one/64

The first case in point is utilizing the “ipv6 deal with” command to assign (configure) an IPv6 Global Unicast Handle (GUA) to an interface. Detect, in the main case in point the “ipv6 tackle” command is demanding the entire IPv6 tackle as well as the prefix-length. The prefix-length (/sixty four) is indicating the amount of high order bits are being used to the network percentage of the GUA.

2. Syntax: Router(config-if)#ipv6 handle ipv6 prefix/prefix-length anycast

Illustration: Router(config-if)#ipv6 address 2001:0DB8:1:one::/sixty four anycast

The second example is utilizing the “ipv6 deal with” command to assign (configure) an IPv6 Anycast Handle to an interface. Recognize, in the 2nd illustration the “ipv6 address” command is only demanding the IPv6 prefix (community part) of the IPv6 deal with along with the prefix-duration, accompanied by the term “anycast”.

three. Syntax: Router(config-if)#ipv6 deal with autoconfig [default]

Illustration:Router(config-if)#ipv6 handle autoconfig

The third case in point is utilizing the “ipv6 tackle” command to generate the interface in concern mechanically autoconfigure itself with an IPv6 handle working with stateless autoconfiguration. You may also utilize the key phrase “default” to produce the interface set up a default route. But remember, the key phrase “default” can only be employed on one interface.

4. Syntax: Router(config-if)#ipv6 deal with ipv6 prefix/prefix-duration eui-64

Example: Router(config-if)#ipv6 deal with 2001:one hundred:one hundred:one hundred::/64 eui-64

The fourth instance is utilizing the “ipv6 handle” command to assign (configure) an IPv6 International Unicast Tackle (GUA) to an interface. But, contrary to the very first illustration; this example is demanding that the “ipv6 address” command make use of the IPv6 prefix (community part) of the IPv6 deal with along with the prefix-duration; followed by the term “eui-sixty four”. In other words, in this example, the interface is going to assign (configure) a GUA to alone; by combining the IPv6 prefix (community portion) which are the initial sixty 4 (/sixty four) higher purchase bits; While using the remaining sixty four minimal-buy bits which happen to be the EUI-sixty four Interface Identifier. The EUI-64 Interface Identifier, is definitely the interface’s layer 2 deal with (MAC Handle) that’s been modified into EUI-sixty four structure.
