Hello,

I have a question concerning this task. Do we really have to manually set the Neighbor Discovery prefix. I did not and it's advertising it.

  • Yep, I have the same question...anyone know or can explain?

  • Still not answered , I have the same qouestion !!

  • CCO cmd ref says:
    http://www.cisco.com/en/US/docs/ios/ipv6/command/reference/ipv6_07.html#wp2359793
    Command Default
    All prefixes configured on interfaces that originate IPv6 router advertisements are advertised with a valid lifetime of 2,592,000 seconds (30 days) and a preferred lifetime of 604,800 seconds (7 days).

    Unless you want to customize the default value, then the command is not necessary.

    HTH

  • By default routers advertises all prefix with default 30 days life time.
    You can change this on per prefix basis using ipv6 nd prefix
    <prefix> valid life time and preferred life time command.

    Better look here my post with example:
