How to write a route correctly?

Question

Computer networks

There are stations with XP and c Win7, connected to the network 10.66.0.0/20, some have a second network 192.168.*.0/24.
In XP, the following routes are formed:

0.0.0.0          0.0.0.0    192.168.100.1   192.168.100.5	  10
        10.66.0.0    255.255.240.0        10.66.8.1       10.66.8.1	  10
        10.66.8.1  255.255.255.255        127.0.0.1       127.0.0.1	  10
=>   10.255.255.255  255.255.255.255        10.66.8.1       10.66.8.1	  10
        127.0.0.0        255.0.0.0        127.0.0.1       127.0.0.1	  1
    192.168.100.0    255.255.255.0    192.168.100.5   192.168.100.5	  10
    192.168.100.5  255.255.255.255        127.0.0.1       127.0.0.1	  10
  192.168.100.255  255.255.255.255    192.168.100.5   192.168.100.5	  10
        224.0.0.0        240.0.0.0        10.66.8.1       10.66.8.1	  10
        224.0.0.0        240.0.0.0    192.168.100.5   192.168.100.5	  10
  255.255.255.255  255.255.255.255        10.66.8.1       10.66.8.1	  1
  255.255.255.255  255.255.255.255    192.168.100.5   192.168.100.5	  1

In the seven routes will differ:

0.0.0.0          0.0.0.0    192.168.100.1    192.168.100.2     20

Interested in marked routes.
Routes have different broadcast addresses.
How to set up to be able to accept both 10.66.15.255 and 10.255.255.255.

Answer 1

I repeat.
route 10.255.255.255 is wrong. This is most likely an attempt to work out the address class. For modern networks, address classes do not matter.
Therefore, you will not be able to train the seven to receive these packets as broadcast ones.
Unless you write your own driver ;)
