IPv6 Addressing Configuration Enabling IPv6 with an Automatically Configured Link-Local Address Enabling IPv6 with an Automatically Configured Link-Local Address This command enables automatic configuration of a link-local address . Syntax: [no] ipv6 enable If IPv6 has not already been enabled on a VLAN by another IPv6 command option described in this chapter, this command enables IPv6 on the VLAN and automatically configures the VLAN's link-local unicast address with a 64-bit EUI-64 inter face identifier generated from the VLAN MAC address. (Refer to "Extended Unique Identifier (EUI)" on page 3-14.). Note: Only one link-local IPv6 address is allowed on the VLAN interface. Subsequent static or DHCP configuration of another link-local address overwrites the existing linklocal address. A link-local address always uses the prefix fe80:0:0:0. With IPv6 enabled, the VLAN uses received router advertise ments to designate the default IPv6 router. (Refer to "Default IPv6 Router" on page 4-30.) After verification of uniqueness by DAD, a link-local IPv6 address assigned automatically is set to the preferred status, with a "permanent" lifetime. (Refer to "IPv6 Address Depreca tion" on page 3-25.) Default: Disabled The no form of the command disables IPv6 on the VLAN if no other IPv6-enabling command is configured on the VLAN. (Refer to "Disabling IPv6 on a VLAN" on page 4-16.) To view the current IPv6 Enable setting and any statically configured IPv6 addresses per-VLAN, use show run. To view all currently configured IPv6 unicast addresses, use the following: ■ show ipv6 (Lists IPv6 addresses for all VLANs configured on the switch.) ■ show ipv6 vlan < vid > (Lists IPv6 addresses configured on the VLAN.) For more information, refer to "View the Current IPv6 Addressing Configura tion" on page 4-22. 4-6
