  1. Hi Rene,

    Do you have lesson configure the RA preferences? More on how the LAN host get the DHCPV6 address and which router will be the elect as default gateway.

    And the show ipv6 router command is something like show arp in IPV4?



  2. Hi Davis

    I know it’s a bit of a late response but just to add onto this. On the client you can also add the syntax “default” after the statement “ipv6 address autoconfig”

    e.g. “ipv6 address autoconfig default”. This will inject a default route on your client.

  3. please check:-
    The big difference between DHCP for IPv6 and DHCPv6 is that we don’t use broadcast traffic anymore”

    I think you mean DHCP for IPv4

  4. Hi Nassir,

    That’s correct, thanks for letting me know. Just fixed it.


  5. Hello Hugues

    When using SLAAC, the addresses that are configured depend on the operating system being used. Specifically for Cisco IOS devices, the EUI64 process is used by default. This means that the actual IPv6 address that a Cisco device will obtain will depend directly on the MAC address of the device itself. If this device is then removed and another device is put in its place, because MAC addresses are unique, the new IPv6 address it will obtain will be different. If the same device is shutdown and restarted, then the same IPv6 address will be assigned to the device once again.

    Well, it really depends on what you want. Typically, for network equipment, it is preferable to use a static address so that remote administration can take place over the same destination IP address.

    I hope this has been helpful!
