Hi Rene,
same scenario how arp will resolution work in case in static route 192.168.2.0 (S 192.168.2.0/24 [1/0] via 192.168.12.2) instead of nexthop as 192.168.12.2 i will configure interface Gi0/2 on R1:
ip route 192.168.2.0 255.255.255.0 Gi0/2
how difference it will make and where actually it is useful . Thanks in advance .
