Section 6.1 says:

 C2: 10.24.16.0/20       \ |    |  _10.24.12.0 - 10.24.15.0__  |    |
                          \|    | / C4: 10.24.12.0/20        \ |    |
                                                 ~~~~~

It should say:

 C2: 10.24.16.0/20       \ |    |  _10.24.12.0 - 10.24.15.0__  |    |
                          \|    | / C4: 10.24.12.0/22        \ |    |

Notes:

~Should be 10.24.12.0/22 as described just above

Section 2 says:

three classes of networks: Class A
(most significant address bits '00'), with 128 possible networks each
and 16777216 end systems

It should say:

three classes of networks: Class A
(most significant address bit '0'), with 128 possible networks each
and 16777216 end systems

Notes:

MSB bits ’00’ would mean that only 6 bits are available for the network part and this would mean only 64 CLASS A networks.

Section 5.3 says:

 Systems that process route announcements must be able to verify that
   information that they receive is acceptable according to policy
   rules.  Implementations that filter route advertisements must allow
   masks or prefix lengths in filter elements.  Thus, filter elements
   that formerly were specified as

      accept 172.16.0.0
      accept 172.25.120.0.0
      accept 172.31.0.0
      deny 10.2.0.0
      accept 10.0.0.0

      accept 10.0.0.0

Notes:

the second network address has 40 bits (5 groups of numbers instead of 4-32 bits).

172.25.120.0.0
