Configuring IPv6

Creating and Applying EAP Method Profiles

You can optionally configure an EAP method list to enable the supplicant to recognize a particular EAP
method. See the “Creating and Applying EAP Method Profiles for the 802.1X Supplicant” section on
page 11-17.
Configuring IPv6
IPv6 is the latest Internet protocol for IPv, developed to provide an extremely large number of addresses.
It uses 128 bit addresses instead of the 32 bit addresses that are used in IPv4.
As deployments in wireless networks use greater number of IP wireless devices and smart phones, IPv6
with its 128-bit address format can support 3.4 x 1038 address space.
IPv6 addresses are represented as a series of 16-bit hexadecimal fields separated by colons (:) in the
format: x:x:x:x:x:x:x:x.
There are three types of IPv6 address types:
•Unicast
The Cisco IOS software supports these IPv6 unicast address types:
–
Aggregatable Global Address
Aggregatable global unicast addresses are globally routable and reachable on the IPv6 portion
of the Internet. These global addresses are identified by the format prefix of 001.
–
Link-Local Address
Link-Local Addressses are automatically configured on interface using link-local prefix
FE80::/10 (1111 1110 10). The interface identifier is in the modified EUI-64 format.
•Anycast can be used only by a router and not the host. Anycast addresses must not be used as the
source address of an IPv6 packet.
•Multicast address is a logical identifier for a group of hosts that process frames intended to be
multicast for a designated network service. Multicast addresses in IPv6 use a prefix of FF00::/8
(1111 1111)
IPv6 configuration uses these multicast groups:
–
Solicited-node multicast group FF02:0:0:0:0:1:FF00::/104
–
All-nodes link-local multicast group FF02::1
–
All-routers link-local multicast group FF02::2
Table 4 -4 lists the IPv6 address types and formats.
