OK, I'll try. ASCII graphics aren't my strong point :-) They are
perfectly legal IP addresses, and they're already advertising them.
But the boxes are on an Ethernet shared with another subnet. The
router's IP address comes from that subnet, and they can't/won't put
an alias on the router port from our network.
---------+---------+-----------+---------
| | +--X.X.X.20
| +-----Y.Y.Y.5
X.X.X.1
|
The Net...
X.X.X.1 is the router on the other network. X.X.X.20 is another
machine on that network. Y.Y.Y.5 is one of my boxes that I'm being
told needs to route to X.X.X.1 (where X!=Y). Both are class C
networks. The router is advertising both class C's to the net.
Does that help any?
