An IPv4 or IPv6 host can use the Port Control Protocol (PCP) to
flexibly manage the IP address-mapping and port-mapping information
on Network Address Translators (NATs) or firewalls to facilitate
communication with remote hosts.  However, the uncontrolled
generation or deletion of IP address mappings on such network devices
may cause security risks and should be avoided.  In some cases, the
client may need to prove that it is authorized to modify, create, or
delete PCP mappings.  This document describes an in-band
authentication mechanism for PCP that can be used in those cases.
The Extensible Authentication Protocol (EAP) is used to perform
authentication between PCP devices.

This document updates RFC 6887.
