Hi everyone, during the training, I was told that when I want to configure the router in the stateless dhcp client mode I have to use the ipv6 enable command (in addition to the ipv6 unicast-routing command to enable routing). So the configuration should be: 1) R3 (config) # ipv6 unicast routing R3 (config) #interface f0 / 0 R3 (config-if) # ipv6 enable R3 (config-if) # ipv6 add autoconfig R3 (config-if) #no shut But while I was running a lab, an exercise asks to configure the router to get the global unicast prefix from another router and the correct procedure is this: 2) R3 (config) # ipv6 unicast-routing R3 (config) #interface f0 / 0 R3 (config-if) # ipv6 add autoconfig R3 (config-if) #no shut The teacher told me to use the ipv6 enable command when not manually configuring the global unicast address; so the command ipv6 enable creates you the local link that should have been created automatically if we had manually configured the global unicast address. The strange thing, however, that I noticed that running the second configuration without "ipv6 enable", the link local address was created automatically with eui-64 why?
