After authentication is completed, the PPP connection is fully
established. At this point, any higher-level protocols (for example,
IP protocols) can initialize and perform their own negotiations and
authentication.
PPP NCPs include support for the following protocols. IPCP and
IPV6CP are the most widely used on J-series devices.
ATCP—AppleTalk Control Protocol
BCP—Bridging Control Protocol
BVCP—Banyan Vines Control Protocol
DNCP—DECnet Phase IV Control Protocol
IPCP—IP Control Protocol
IPV6CP—IPv6 Control Protocol
IPXCP—Novell IPX Control Protocol
LECP—LAN Extension Control Protocol
NBFCP—NetBIOS Frames Control Protocol
OSINLCP—OSI Network Layer Control Protocol (includes
IS-IS, ES-IS, CLNP, and IDRP)
SDTP—Serial Data Transport Protocol
SNACP—Systems Network Architecture (SNA) Control
Protocol
XNSCP—Xerox Network Systems (XNS) Internet Datagram
