Chapter4 Configuring the Access Point for the First Time
Configuring IPv6
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 -6 lists the IPv6 address types and formats.
The following modes are supported
Root
Root bridge
Non Root bridge
Repeater
WGB
The following modes are not supported
Spectrum mode
Monitor mode
Beginning in privileged EXEC mode, use these commands to enable tie ipv6 address
ap(config)# int bv1
ap(config-if)# ipv6 address
A link-local address, based on the Modified EUI-64 interface ID, is automatically generated for the
interface when stateless autoconfiguration is enabled.
Beginning in privileged EXEC mode, use the following command to enable stateless autoconfiguration:
ap(config-if)# ipv6 address autoconfig
Beginning in privileged EXEC mode, use the following command to configure a link local addreess
without assigning any other IPv6 addressesto the interface:
ap(config-if)# ipv6 address ipv6-address link-local
