I'm not sure if I make myself clear. I assigned the same TrBRF and 2
diffrent TrCRFs to 2 rotuters,and then I tried to assing the same ring
number to TrCRFs, when I got en error message saying that ring # has been
already allocated.
So the questions is -Was I doing something wrong or this is normal behaviour
for switch. What am I driving at is if we have diagram with 2 routers
attached to the same ring(lets say 200), does it mean we need actually 2
different # 200 and 201 to implement this on the TR Switch.?
