clean up, typos fixed: ie → i.e.
At this stage, there should be basic IPv6 connectivity to link-local, and if static routes and manually assigned addresses in place you should have a working connection.
Optionally, if routes and addresses have not been configured statically, DHCPv6 can be used for automatic negotiation of the IPv6 WAN and LAN prefixes - using DHCPv6 is usually the default for our routers (
ie the ZyXEL) that we supply.
When DHCPv6 is enabled, the CPE sends a DHCPv6 Solicitation to the IPv6 broadcast address, containing a list of options that it requires.
Once we receive the DHCPv6 Solicitation, the LNS you are connected to will send a reply containing responses to the options requested. The CPE can then take the options and apply them as appropriate.
