What does the entire routing table look like? If those routes are using the
same subnet mask they will not show the mask in their individual entries.
However, above those routes there should be an entry in the table that shows
the major network, what subnet mask the routes below it have, and how many
routes are using that subnet mask.
For example, in this output the 10.0.0.0 major network is subnetted into 11
24-bit networks. The only place where the subnet mask information is stated
is in the first line. All of the other networks that are indented and
listed below it have that subnet mask (24-bit).
10.0.0.0/24 is subnetted, 11 subnets
O 10.11.1.0 [110/2] via 10.10.1.1, 03:15:37, Vlan10
C 10.10.1.0 is directly connected, Vlan10
O 10.15.1.0 [110/11123] via 10.40.1.4, 03:15:37, Vlan40
O 10.14.1.0 [110/2] via 10.40.1.4, 03:15:37, Vlan40
O 10.12.1.0 [110/2] via 10.20.1.2, 03:15:37, Vlan20
O 10.34.34.0 [110/11112] via 10.40.1.4, 03:15:37, Vlan40
C 10.35.35.0 is directly connected, Port-channel1
O 10.16.1.0 [110/2] via 10.60.1.6, 03:15:37, Vlan60
C 10.20.1.0 is directly connected, Vlan20
C 10.40.1.0 is directly connected, Vlan40
C 10.60.1.0 is directly connected, Vlan60
