- Recently we have purchased an SBUS ethernet controler for one of our
- backbone SUN's under the pretense that we could route between two
- logical subnets on the same physical network. That is we have run out
- of IP addresses in the backbone subnet and were attempting to run
- another gateway between the new subnet. This doesn't work due to the
- ethernet controler not having its own MAC address (uses the internal
- controlers address). This causes re-occuring broadcast storms on the
- local ethernet not to mention numerous other problems.
-
- Since then we have turned off ip-forwarding in the kernel and told routed
- not to supply RIP update's. This stops the broadcast stroms and still
- allows our BOOTP (etc...) requests on the new subnet but still doesn't
- fix the problem we were intending. ie. adding another gateway to route
- between the two subnets.
-
- Has anyone been in the same situation or any ideas would be would be
- much appreciated.

- Thankyou,
