page 36-18). This address type makes the router accessible over IPv6
for all devices attached to the same local subnet.
• If a duplicate address is detected on the local segment, this interface
will be disabled and a warning message displayed on the console.
• The no ipv6 enable command does not disable IPv6 for an interface
that has been explicitly configured with an IPv6 address.
Example
In this example, IPv6 is enabled on VLAN 1, and the link-local address
FE80::200:E8FF:FE90:0/64 is automatically generated by the router.
Console(config)#interface vlan 1
Console(config-if)#ipv6 enable
Console(config-if)#end
Console#show ipv6 interface
Vlan 1 is up
IPv6 is enable.
Link-local address:
FE80::200:E8FF:FE90:0/64
Global unicast address(es):
Joined group address(es):
FF01::1/16
FF02::1/16
FF02::1:FF90:0/104
MTU is 1500 bytes.
