Internet Engineering Task Force (IETF) M. Boucadair Request for Comments: 7291 France Telecom Category: Standards Track R. Penno ISSN: 2070-1721 D. Wing Cisco July 2014 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.

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]. Boucadair, et al.
