Configuring IPv6
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
Beginning in privileged EXEC mode, use the following command to assign a site-local or global address
to the interface:
ap(config-if)# ipv6 address ipv6-address [eui-64]
Note The optional eui-64 keyword is used to utilize the Modified EUI-64 interface ID in the low order 64 bits
of the address.

Configuring DHCPv6 address
DHCPv6 is a network protocol that is used for configuring IPv6 hosts with IP addresses, IP prefixes and
other configuration required to operate on an IPv6 network. The DHCPv6 client obtains configuration
parameters from a server either through a rapid two-message exchange (solicit, reply), or through a
These modes are supported:
•Root
•Root bridge
•Non Root bridge
•Repeater
•WGB
These modes are not supported:
•Spectrum mode
•Monitor mode
These are also not supported in IPv6:
•SNMPv6
•Multiple BVI interfaces on an access point
•Enabling IPv6 on any interface other than BVI
Beginning in privileged EXEC mode, use these commands to enable the ipv6 address
