Adding to Bruce's comments...  He caught the reference to class C instead
of class B.  There are a couple minor mistakes in the suggested entries,
though.

The subnet mask and value were mis-positioned by an octet.  Assuming
your host is on the class C sized subnet, 130.127.8, of your class B
network, this should be:

     130.127        =             ETH3 1500        0.0.255.0 0.0.8.0

Again, this should be:

     130.127        130.127.8.108 ETH3 1500        0.0.255.0 0.0.72.0

That one's fine.

The assumption (on the first entry) is that your host is on a class C
subnet.  If that isn't correct, the first entry, and maybe the second,
need to be changed somewhat.
