- Link Local—An IPv6 address that uniquely identifies hosts on a single
network link. A link local address has a prefix of FE80, is not routable, and
can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
- Global—An IPv6 address that is a global Unicast IPV6 type that is visible
and reachable from other networks.
- Anycast—(Layer 3 only) The IPv6 address is an Anycast address. This is
an address that is assigned to a set of interfaces that typically belong to
different nodes. A packet sent to an Anycast address is delivered to the
closest interface—as defined by the routing protocols in use—identified
by the Anycast address.
NOTE Anycast cannot be used, if the IPv6 address is on an ISATAP interface.
• IPv6 Address—In Layer 2, the device supports one IPv6 interface. In
addition to the default link local and Multicast addresses, the device also
automatically adds global addresses to the interface based on the router
advertisements it receives. The device supports a maximum of 128
addresses at the interface. Each address must be a valid IPv6 address that
is specified in hexadecimal format by using 16-bit values separated by
colons.You cannot configure an IPv6 addresses directly on an ISATAP tunnel
interface.
• Prefix Length—The length of the Global IPv6 prefix is a value from 0-128
indicating the number of the high-order contiguous bits of the address
comprise the prefix (the network portion of the address).
• EUI-64—Select to use the EUI-64 parameter to identify the interface ID
portion of the Global IPv6 address by using the EUI-64 format based on a
device MAC address.
STEP 4 Click Apply. The Running Configuration file is updated.
IPv6 Router Configuration
The following sections describe how to configure IPv6 routers.
Router Advertisement
IPv6 routers are able to advertise their prefixes to neighboring devices. This
feature can be enabled or suppressed per interface, as follows:
