Section 8.2.2 says:

on page 72, description of the Established state:

If the HoldTimer_Expires event occurs (Event 10), the local system:
 ...[list of actions to take]...

It should say:

If the HoldTimer_Expires event occurs (Event 10), the local system:
 - deletes all routes associated with this connection
 ...[list of actions in original text]...

Notes:

All other transitions from Established to Idle explicitly state that all routes associated with the connection are deleted. This transition should as well.

Section 6.3 says:

   If an optional attribute is recognized, then the value of this
   attribute MUST be checked.  If an error is detected, the attribute
   MUST be discarded, and the Error Subcode MUST be set to Optional
   Attribute Error.  The Data field MUST contain the attribute (type,
   length, and value).

It should say:

   If an optional attribute is recognized, then the value of this
   attribute MUST be checked.  If an error is detected, the Error 
   Subcode MUST be set to Optional Attribute Error.  The Data 
   field MUST contain the attribute (type, length, and value).

Notes:

This simply removes the clause "the attribute MUST be discarded", which doesn't make sense since the peering is to be terminated anyway.

              10 - Invalid Network Field.
              11 - Malformed AS_PATH.

Notes:

RFC 4271 defines a use and a name for Error subcode 0:
- §4.5 (any error code):
If no appropriate Error Subcode is defined, then a zero
(Unspecific) value is used for the Error Subcode field.

- §6.2 (OPEN error code):
If one of the Optional Parameters in the OPEN message is recognized,
but is malformed, then the Error Subcode MUST be set to 0
(Unspecific).

The "IANA Considerations" section would also need to be updated
accordingly (says "0 Reserved”). However, IANA has corrected the
corresponding registry at http://www.iana.org/assignments/bgp-parameters.

Section 9.2.2.2 says:

         route MUST have the ORIGIN attribute with the value EGP.  In
         all other cases,, the value of the ORIGIN attribute of the

It should say:

         route MUST have the ORIGIN attribute with the value EGP.  In
         all other cases, the value of the ORIGIN attribute of the
         aggregated route is IGP.
