Tell me more ×  The setup:  We are an apartment complex with
approximately 1700 units. Every apartment has internet with an
ethernet plug in each. The network has 60 HP 2910al-48G switches
connected to a central HP 5412 core switch.  The tenants can
plug in their PC directly to the network or they can buy their
own home gateway and plug that in. Tenants also have the option
of using a dump L2 switch to connect multiple PC's. Some tenants
have a SIP phone with a buildin 2 port switch.  The problem:  We
want to provide IPv4 and IPv6 with L2 separation between
apartments. We want to avoid sharing a VLAN between multiple
apartments. We want to avoid broadcast chatter between
apartments. For example, Windows PCs should not automatically
discover any devices at your neighbor.  Due to the IPv4
exhaustion issue, we can not allocate a full IPv4 subnet to each
apartment. We do not wish to deploy NAT.  We want to allocate a
unique /64 IPv6 subnet to each apartment. Additionally we want
to provide /60 subnets to home gat
