I hate bridging!
Good luck Ray. I'm going to go home now. I haven't been able to get it to
work either. I just remembered we reconfigred our Token-Ring switch the
other day and I don't know what the bridge number is. I'll come in early
tomorrow and get everything worked out with that and reconfigure everything.
I was going for the idea of using source-route bridging on the Token-Ring
connection between r1 and r7, and transparent bridging on the serial link
between r1 and r5, then doing SR/TLB on r1 to go between the two.
