Abstract Abstract
In some IPv6 environments, the need has arisen for hosts to be able In some IPv6 environments, the need has arisen for hosts to be able
to utilize a unique IPv6 prefix, even though the link or media may be to utilize a unique IPv6 prefix, even though the link or media may be
shared. Typically hosts (subscribers) on a shared network, either shared. Typically hosts (subscribers) on a shared network, either
wired or wireless, such as Ethernet, WiFi, etc., will acquire unique wired or wireless, such as Ethernet, WiFi, etc., will acquire unique
IPv6 addresses from a common IPv6 prefix that is allocated or IPv6 addresses from a common IPv6 prefix that is allocated or
assigned for use on a specific link. assigned for use on a specific link.

When a UE connects to the shared provider managed network and is When a UE connects to the shared provider managed network and is
attached, it will initiate IP configuration phase. During this phase attached, it will initiate IP configuration phase. During this phase
the UE will, from an IPv6 perspective, attempt to learn the default the UE will, from an IPv6 perspective, attempt to learn the default
IPv6 gateway, the IPv6 prefix information, the DNS information IPv6 gateway, the IPv6 prefix information, the DNS information
RFC6106 [RFC6106], and the remaining information required to RFC8106 [RFC8106], and the remaining information required to
establish globally routable IPv6 connectivity. For that purpose, the establish globally routable IPv6 connectivity. For that purpose, the
the UE/subscriber sends a RS (Router Solicitation) message. the UE/subscriber sends a RS (Router Solicitation) message.
The First Hop Router receives this UE/subscriber RS message and The First Hop Router receives this UE/subscriber RS message and
starts the process to compose the response to the UE/subscriber starts the process to compose the response to the UE/subscriber
originated RS message. The First Hop Provider Router will answer originated RS message. The First Hop Provider Router will answer
using a unicast RA (Router Advertisement) to the UE/subscriber. This using a unicast RA (Router Advertisement) to the UE/subscriber. This
RA contains two important parameters for the EU/subscriber to RA contains two important parameters for the EU/subscriber to
