- My first advice is to go out and buy Novell's MultiProtocol Router
- v2.0, which supports multiple subnets on a single physical network.
- Since you really are using your NetWare server as a full time router,
- you might find this worth the price. (I'm not sure our sales or
- marketing guys ever mention this, but MPR v2.0 can be run on a normal
- NetWare server if the server has enough spare cycles: it doesn't
- require a standalone PC.)

- >My questions:
-
- I'll answer these under the assumption that you are only using NetWare
- v3.11, just in case you don't want to buy MPR v2.0.

-
- The RIP information should have been propagated, and i'm not entirely
- sure why it wasn't. It sounds like your primary gateway isn't telling
- the whole story with its RIP packets.

-
- TCPIP.NLM will receive and interpret RIP broadcasts to
- 255.255.255.255, so the destination address is not the reason it
- didn't see them. It was probably just ignoring the RIP broadcasts
- with a source IP address that wasn't on what it considered a directly
- connected network, which seems reasonable.

-
- The GATEWAY parameter does place a default route into the routing
- table. In your case, you'd put a GATEWAY parameter on the bind to the
- backbone network, and give it the address of the primary router.
- After that, when the NetWare router receives packets intended for the
- secondary subnets (i.e., the subnets it doesn't actually know about),
- it will send them to the primary router for "forwarding" to the other
- subnets sharing the physical network.
-
- >4. Is there anything else that I may have overlooked?
-
- MPR v2.0, mainly. Also, it sounds like the primary router is doing
- some hinky things which make it harder than it should be to put nodes
- without multiple subnet support on the backbone network. You might
- want to explore that a little further in case it's doing something
- that can confuse other nodes.
