You can do a "sho ip rout list <access-list>"

Here's an example with an access-list for all class "A" addresses:

R4#sho ip rout list 10
10.0.0.0/24 is subnetted, 1 subnets
D 10.1.1.0 [90/2297856] via 172.16.5.1, 00:02:50, Serial0/0
R4#sho access-list 10
Standard IP access list 10
permit 0.0.0.0, wildcard bits 127.255.255.255

Here's one for all routes with a /24 mask.

R4#sho ip rout list 100
     172.16.0.0/24 is subnetted, 5 subnets
I 172.16.4.0 [100/1600] via 172.16.1.1, 00:00:22, Ethernet0/0
C 172.16.5.0 is directly connected, Serial0/0
C 172.16.1.0 is directly connected, Ethernet0/0
I 172.16.2.0 [100/1600] via 172.16.1.1, 00:00:22, Ethernet0/0
I 172.16.3.0 [100/1600] via 172.16.1.1, 00:00:22, Ethernet0/0
     10.0.0.0/24 is subnetted, 1 subnets
D 10.1.1.0 [90/2297856] via 172.16.5.1, 00:03:32, Serial0/0
D 192.168.0.0/24
R4#sho access-list 100
Extended IP access list 100
    permit ip any host 255.255.255.0 (18 matches)
