Reference
[RFC1661][RFC3818]
Note
The Point-to-Point Protocol (PPP) Data Link Layer [RFC1331][RFC1332][RFC1353]
contains a 16 bit Protocol field to identify the the encapsulated
protocol.  The Protocol field is consistent with the ISO 3309 (HDLC)
extension mechanism for Address fields.  All Protocols MUST be
assigned such that the least significant bit of the most significant
octet equals "0", and the least significant bit of the least
significant octet equals "1".

It is recommended that values in the "02xx" to "1exx" and "xx01" to
"xx1f" ranges not be assigned, as they are compression inefficient.

Note
PPP Vendor Extensions [RFC2153] uses IEEE standard OUIs
(Organizationally Unique Identifiers) to indicate vendor-specific
features.  See [RFC1700] for details on contacting the IEEE.
Vendors that desire to use their IEEE 802 OUI for PPP Vendor
Extensions should register their OUI with IANA.  Vendors that do
not otherwise need an IEEE assigned OUI can request a PPP
specific OUI from IANA out of the 'CF0000' range, which has both
the "locally-assigned" and "broadcast/multicast" bits set to one.
See [RFC2153] for details.

Note
IPV6CP Configuration Options allow negotiation of desirable IPv6

for LCP, with a separate set of Options.  If a Configuration Option is
not included in a Configure-Request packet, the default value for that
Configuration Option is assumed.
