I am migrating a FDDI bridged network into a routed one, for that a 6509 with sup720 has been installed.
Everything seems to be OK until i tried to browse the XDMCP servers available, none appear (it should list dozens of Unix servers).
I assume that the servers are listening to broadcasts but i am failing to get those broacasts to get from remote VLANs. Only the same segment servers appear on the list. I have tried ip helper address and it does not seem to work.
The problem is solved. I was already using the "ip directed-broadcast" command but by some reason (human error most probably) when I introduced the command "ip helper-address" and "ip forward-protocol xdmcp" it did not enter correctly.
So all it was needed(after many hours) was to re-type the sequence and all went smooth.
