  1. Hi Ahammad,

    With DHCPv6, we don't advertise a default gateway. We use the router advertisements to figure out what router to use as the default gateway.

    DHCPv6 is only used to supply IPv6 addresses and things like DNS, domain names, NTP servers, etc.

  3. Hello Abey.

    Others have had similar problems. It all depends on the version of IOS you're using and the platform. Take a look at this post which includes some IOS versions and platforms on which it has been successfully implemented.

    However, using your version it is possible to implement the same thing using the prefix-delegation command. If you're interested, you can find out more information about that here.

    I hope this has been helpful!


  4. Thank you Laz. Your reply is most appreciated. Have a Great Day !!

  5. Hello Thanh

    Take a look at this Cisco Command Reference for the command. Take a look at the IOS versions that support this command and compare with your devices…

    Let us know what you find…

    I hope this has been helpful!
