Examples from the man page

       An example with common network interfaces and some static routes:

       # --- IPv4 routes in CIDR prefix notation:
       # Destination [Gateway] - Interface
       #
       127.0.0.0/8 - - lo
       204.127.235.0/24 - - eth0
       default 204.127.235.41 - eth0
       207.68.156.51/32 207.68.145.45 - eth1
       192.168.0.0/16 207.68.156.51 - eth1

       # --- IPv4 routes in deprecared netmask notation:
       # Destination [Dummy/Gateway] Netmask Interface
       #
       127.0.0.0 0.0.0.0 255.255.255.0 lo
       204.127.235.0 0.0.0.0 255.255.255.0 eth0
       default 204.127.235.41 0.0.0.0 eth0
       207.68.156.51 207.68.145.45 255.255.255.255 eth1
       192.168.0.0 207.68.156.51 255.255.0.0 eth1

       # --- IPv6 routes are always using CIDR notation:
       # Destination [Gateway] - Interface
       #
       2001:DB8:100::/64 - - eth0
       2001:DB8:100::/32 fe80::216:3eff:fe6d:c042 - eth0
