Entry details

Here's what a routing table entry looks like:

C    192.168.1.0/24 is directly connected, GigabitEthernet0/0
S    10.0.0.0/8 [1/0] via 192.168.1.1
O    172.16.0.0/16 [110/20] via 192.168.1.2, 00:05:32, Gi0/1

The letter at the start indicates the route source:

C: Connected (directly attached network)
S: Static (manually configured)
O: OSPF (learned dynamically)
R: RIP (learned dynamically)

The numbers in brackets show $[\text{Administrative Distance}/\text{Metric}]$ . Lower values are preferred. The interface or next-hop address tells the router where to send matching packets.
