IPv6 Address Types
IPv6 uses multicast addresses instead of the broadcast address. An IPv6 address can be
classified into one of three categories, which Unicast, Multicast and Anycast address. The
Anicast address, a new type of address introduced with RFC 1546, is now used with IPv6.
An anycast address is assigned to multiple interfaces. A packet sent to an anycast
address is delivered to only one of these interfaces, usually the nearest one.
IPv6 Special Addresses
There are some special addresses without prefix.
- Unspecified address : the unspecified address for IPv6
0000 : 0000 : 0000 : 0000 : 0000 : 0000 : 0000 : 0000 (or ::)
- Localhost address : the special address for the loopback interface.
0000 : 0000 : 0000 : 0000 : 0000 : 0000 : 0000 : 0001 (or ::1)
- Link local address : It is assigned automatically to an interface when IPv6 is enabled.
The link local address is used only on local links for link communication purposes.
These addresses typically begin with fe80.
- Site local address : These addresses typically begin with fec0 and are used within a
site. They are not for global use.
- Multicasting addresses : Multicast capability is formally added into the IPv6 protocol.
The multicasting addresses begin with ff0x, where x is any hexadecimal number. An
example of multicast address is ff02::1. This stands for all nodes of an address.
You can enable the interface to communicate with another network device on the network
by assigning an IPv6 address
4.4.1 Enabling Interface
To assign an IP address to an interface, you need to enable the interface first. If the
interface is not enabled, you cannot access it from a remote place, even though an IP
address has been assigned.
To configure an interface, you need to open Interface Configuration mode first. To open
Interface Configuration mode, use the following command.
Opens Interface Configuration mode to configure a
specified interface.
To enable/disable an interface, use the following command.
