You may get better luck on the ipv6-ops list but here's some information for you: Assuming you are using a /64 netmask for your local lan, you likely want to be using ipv4 dhcp + SLAAC (basically stateless autoconfig) for IPv6. You will have the router send out RA (router advertisement) messages. End-hosts will listen to those and assign an address within the broadcast domain. If you have multiple subnets, the hosts may auto-dual-home themselves. Something that may be unexpected for people, but important to mention. You can tune the timers related to these RA messages. This is the high-level view. If you really mean DHCPv6, that is something a bit more complex to talk about. You need a pool, and then to decide what size prefix you will sub-delegate, etc.. Some may suggest a /64, others something larger. Me? I suggest you let SLAAC do its thing, send RAs and do a /64 on the subnet. I don't have a good config example handy to share, but I'm sure there are some out there. - Jared _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
