What routes are automatically set up?
A few routes automatically get set up every time your machine is booted. First, all machines will always have a localhost route back to themselves: Destination Gateway Flags Ref Use Interface ——————– ——————– —– —– —— ——— 127.0.0.1 UH 0 591 lo0 This is standard and increases the efficiency of packets that a machine sends to itself. Second, Solaris machines have a special multicast route: 224.0.0.0 150.101.16.28 U 3 0 le0 Multicast routes are used by certain programs that broadcast to a group of machines rather than to the subnet in general. Finally, all machines will always set up one route for each of their interfaces. The route will be a simple one which says that all packets which go to the interface’s network should be routed through the interface. For example, I have one interface, le0, with an IP address of 150.101.16.28. Since I use a netmask of 255.255.255.0, this means that my local network is 150.101.16.0, and the route looks like this
