A host may have multiple network interfaces (e.g., 3G, IEEE 802.11, etc.), each configured with different PCP servers. Each PCP server learned must be associated with the interface on which it was learned. Generic multi-interface considerations are documented in Section 8.4 of [RFC6887]. Multiple PCP server IP addresses may be configured on a PCP client in some deployment contexts such as multihoming (see Appendix A). A PCP server may also have multiple IP addresses associated with it. It is out of the scope of this document to enumerate all deployment scenarios that require multiple PCP server IP addresses to be configured.
