Thats what I thought, however it does not cut it...
Below is the list of my networks. As you notice, there is one /29 specific in
there. I need to come up with an ACL that would only leak that route...
access-list 101 permit ip 178.2.8.248 0.0.0.0 255.255.255.248 0.0.0.0

or

access-list 101 permit ip 0.0.0.0 255.255.255.255 255.255.255.248 0.0.0.0

dont pass anything
D EX 178.2.8.248/29 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1
D EX 178.2.1.0/24 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1
D EX 178.2.2.0/24 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1
D EX 178.2.3.0/24 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1
D EX 178.2.4.0/24 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1
D EX 178.2.5.0/24 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1
D EX 178.2.6.0/24 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1
D EX 178.2.7.0/24 [170/409600] via 150.100.3.254, 00:00:26, Ethernet0/1

Wouldn't it be

access-list 101 permit ip 0.0.0.0 255.255.255.255 255.255.255.248 0.0.0.0

Hello,

What is the access-list equivalency to the following prefix list for
distribution list purposes:

ip prefix-list SUB29 seq 5 permit 0.0.0.0/0 ge 29 le 29

Thanks!
