D为31<2^6-2,192.168.20.64 - 192.168.20.127(掩码为26)
C为12<2^4-2,192.168.20.128 - 192.168.20.143(掩码为28)
B为6<2^3-2,192.168.20.144 - 192.168.20.151(掩码为29)
8、
202.102.32.32/27，202.102.32.32 - 202.102.32.63
202.102.32.64/28，202.102.32.64 - 202.102.32.79
202.102.32.96/28，202.102.32.96 - 202.102.32.111
A为这三个聚合为202.102.32.0/25，202.102.32.0 - 202.102.32.127

B为202.102.32.136/29，202.102.32.136 - 202.102.32.143

202.102.32.144/29，202.102.32.144 - 202.102.32.151
202.102.32.152/29，202.102.32.152 - 202.102.32.159
C可聚合成202.102.32.144/28，202.102.32.144 - 202.102.32.159

D为B和C的聚合202.102.32.128/27，202.102.32.128 - 202.102.32.159

E为A、D的聚合202.102.32.0/24
