    Good article…

    Making it a little more comprehensive will make it a lot better and one of the best learning source especially for starters.

  2. Thanks. I’ll add some more IPv6 stuff in the feature, especially since the new CCNA exams cover much more IPv6 then the previous version.

  3. Hi Davis,

    It is similar to how IPv4 default routes work. Instead of we use ::/0 for IPv6. You can advertise this with routing protocols or use a static route.

    The default gateway works a bit differently.

    A host will receive router advertisement(s) from all routers on the subnet. The router with the highest RA preference will be used as the default gateway.


  4. 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?



  5. 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.
