DHCP Options for the Port Control Protocol (PCP)
Abstract
This document specifies DHCP (IPv4 and IPv6) options to configure
hosts with Port Control Protocol (PCP) server IP addresses. The use
of DHCPv4 or DHCPv6 depends on the PCP deployment scenarios. The set
of deployment scenarios to which DHCPv4 or DHCPv6 can be applied is
outside the scope of this document.

1. Introduction
This document defines DHCPv4 [RFC2131] and DHCPv6 [RFC3315] options
that can be used to configure hosts with PCP server [RFC6887] IP
addresses.
This specification assumes a PCP server is reachable with one or
multiple IP addresses. As such, a list of IP addresses can be
returned in the DHCP PCP server option.
This specification allows returning one or multiple lists of PCP
server IP addresses. This is used as a hint to guide the PCP client
when determining whether to send PCP requests to one or multiple PCP
servers. Concretely, the PCP client needs an indication to decide
whether entries need to be instantiated in all PCP servers (e.g.,
multi-homing, multiple PCP-controlled devices providing distinct
services, etc.) or use one IP address from the list (e.g., redundancy
group scenario, proxy-based model, etc.). Refer to [PCP-DEPLOYMENT]
for a discussion on PCP deployment scenarios.
For guidelines on how a PCP client can use multiple IP addresses and
multiple PCP servers, see [PCP-SERVER].
