If I understand your question correctly. It says "allow all routes
below 10.0.0.0/8". Which means 8 and 9 networks are allowed but not 10
and 11 networks.

My working config is below :

R2(config)#do sh run | b router
router eigrp 1
 network 0.0.0.0
 distribute-list prefix ALLOW-BELOW10 in Serial1

######## OPTION 1:
ip prefix-list seq 5 ALLOW-BELOW10 deny 10.0.0.0/7 ge 8
ip prefix-list seq 10 ALLOW-BELOW10 permit 0.0.0.0/0 le 32

######## OPTION 2:
ip prefix-list ALLOW-BELOW10 seq 5 permit 8.0.0.0/7 ge 8 le 8
