Configuring a link-local IPv6 address on an Interface

You can configure link-local IPv6 addresses at the interface level.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Enter interface configuration mode. 
    device(config)# interface ethernet 1/1/1
  3. Configure a link-local IPv6 address for the interface. 
    device(config-if-e1000-1/1/1)# ipv6 address FE80::240:D0FF:FE48:4672 link-local

The following example explicitly configures a link-local IPv6 address for an Ethernet interface. 

device# configure terminal
device(config)# interface ethernet 1/1/1
device(config-if-e1000-1/1/1)# ipv6 address FE80::240:D0FF:FE48:4672 link-local
