I'm given 2001: ABCD: DCBA:6660::/60 by my ISP. I want to split it up into 4 subnets. I have 1 router connected to 4 switches and so on. Can I do 2001: ABCD: DCBA:6660::/64 2001: ABCD: DCBA:6661::/64 2001: ABCD: DCBA:6662::/64 2001: ABCD: DCBA:6663::/64 I went to my router, enabled unicast-routing, then set int f0/0 to ipv6 addr 2001:ABCD:DCBA:6660::1/64 int f0/1 to next subnet, and so on... My PC's all get correct IPs, but they can ping each other. That IS what I want, but feel like they shouldn't be able to ping each other. IPv6 has my head spinning and I don't really know why. This should be easy :( Do I need to set link-local addresses?

That is indeed proper subnetting with IPv6. And with a router, they will be able to ping each other unless you add some IPv6 access lists to block the traffic. Also, every IPv6 interface will automatically get a link local address as well. They'll typically get one using EUI64 rules, but some devices just assign a random link local address and then rely on duplicate address detection to avoid conflicts. --- https://i.imgtc.com/d9Fc4Qq.gif https://i.imgtc.com/BKHTxYq.gif https://i.imgtc.com/vYYIuDx.jpg ...

If a firewall was your layer 3 device, it would block traffic between interfaces and subnets by default unless you explicitly allow it. With a router, it will deliver traffic between interfaces and subnets by default as long as both the source and destination subnets are in the routing table. --- https://i.imgtc.com/d9Fc4Qq.gif https://i.imgtc.com/BKHTxYq.gif https://i.imgtc.com/vYYIuDx.jpg ...

Thanks a lot! I think the problem I had in another lab was that it was traffic between two routers that I had to route. Never tried to just ping between subnets on the same router in IPv6 and it freaked me out; it seemed "too easy.: In between my last post and this I set up VLAN's and they seem to work. --- "You're sorely underestimating the power of nostalgia goggles." - adjl http://www.smbc-comics.com/comics/20110218.gif ...
