Hi all,
This is a bit of a silly question, but I have looked for an answer and can't seem to put my finger on it. We have a SG500X-24 stackable switch as our core switch in our network. It manages a handful of VLANs and acts as the default route for most of them.
I'm tinkering around with getting IPv6 going — using Unique Local Addresses. There's no IPv6 service on the Internet connection (yet), but I have found it handy in the past to set up 6-in-4 tunnels to various customer sites and use NAT64 to work around clashing IPv4 address space, so dispite the lack of public IPv6 Internet access, having the network dual-stack has its uses.
Seeing as our core IPv4 router is the SG500X, and it does a good job here, it makes sense to make it our core IPv6 router too. Setting it up as an IPv4 router involves setting up multiple IPv4 interfaces; one on each VLAN. Easy enough, now try doing the same with IPv6.
I've created an IPv6 address on the management VLAN, no problem, that works fine. Now, to create one on the client network where my laptop is. I go into the IPv6 Interfaces, choose the VLAN interface, click Add, type the address in, hit Apply (same as I did before for the management VLAN). No dice; I'm told that I've already configured the maximum number of interfaces — one interface, as it happens!
Has anyone else had any luck setting this up on these switches, or do I need to have a separate IPv6 router on each VLAN?
