Selecting the Type of Addressing Used on the CPE
In some networks, you do not need to assign a global IPv6 address on the CPE WAN link. Your decision depends on the type of CPE being used:
- If the CPE is purchased by the subscriber, and is not a device specifically recommended by the service provider, you need to assign a global IPv6 address that can be routed on the Internet.
- If the CPE is supplied by or recommended by the service
provider, you can use the loopback interface to manage the CPE.
In this case, you can use a link-local address or you can use an address that is derived from DHCPv6 prefix delegation.
