Section 4.3 says:

Sequence Number

      The sequence number for this packet.  For Keyed MD5
      Authentication, this value is incremented occasionally.  For
      Meticulous Keyed MD5 Authentication, this value is incremented for
      each successive packet transmitted for a session.  This provides
      protection against replay attacks.

It should say:

Sequence Number

      The sequence number for this packet.  For Keyed MD5
      Authentication, this value is incremented (by one) occasionally.  For
      Meticulous Keyed MD5 Authentication, this value is incremented by one for
      each successive packet transmitted for a session.  This provides
      protection against replay attacks.

Notes:

This change clarifies the amount by which the sequence number is incremented.

Section 6.8.6 says:

Set bfd.RemoteState to the value of the State (Sta) field.

It should say:

Set bfd.RemoteSessionState to the value of the State (Sta) field.

Notes:

The variable bfd.RemoteState is not defined in section 6.8.1 and is only mentioned once in the entire document. It is likely a typo and a similarly named bfd.RemoteSessionState was meant instead.
