RFC-Editor Note
Please add this to the IANA Considerations section:
IANA is requested to create and maintain a registry for OPEN message
optional parameters called "BGP OPEN Optional Parameter Types". Optional
parameters are identified by the Parameter Type, which is a one-octet
unsigned integer. Values (0 reserved, 1-255) are to
be allocated according to the "IETF Review" policy as defined in
[RFC5226].
The registry should be populated with the two Parameter Type codes
that are currently defined:
o Parameter Type 1: Authentication (deprecated).
o Parameter Type 2: Capabilities ([RFC3392bis])
IANA Note
See RFC-Editor note for instructions on the new registry.
