- Can you elaborate on this last point? Are IBM and Cisco using different
- rules for source-route bridging? Why didn't it work? We have parallel
- Ethernet and Token-ring networks and I'm wondering if something in the
- Cisco source-route code doesn't handle loops correctly. The only thing
- that is clear is that it isn't working for us, yet. The code seems
- sensitive to something in our net and isn't reliable, yet.
