I set up my new practice rack at home using 3 2950s, 2 3640s, 1 2610, 1 2610XM, and 2509 Access Server.
All the gear comes up fine, and takes CLI commands. I setup the access server according to a config I found at the Bryant Advantage. I named the routes R1, R2, R3, R4, and the switches S1, S2, S3. Afer setup I was able to access each box in order. I used the hostname to get into them. Then when I tried cycling back through them again, some said access denied, some acted like they were not there. To access R1 I have tried the command R1 and 1, but both give the same lack of connection.
If I reboot the rack, I can access some and not the others. Sometimes I can get right in to R3, sometimes only into R4.
I have been comparing the configs of the differnet routers to see what is different, but not have found the problem.
