The two example ip route commands show the two different styles. The first command shows subnet 172.16.2.0, mask 255.255.255.0, which sits in the datacenter near Nexus R2. That same first command lists 172.16.4.2, R2’s IP address, as the next-hop router. This route basically says this: To send packets to the subnet off Nexus R2, send them to R2.

The second route has the same kind of logic, but instead of identifying the next router by IP address, it lists the local router’s outgoing interface. This route basically states: To send packets to the subnet off router R3, send them out my own local Ethernet 1/1 interface (which happens to connect to R3).
