A part of a test of the CISCO router was the following configuration:
+-----+ +----+ +-----------------+
-----|CISCO|---|X.25|---|SUN, X25 software|
^ +-----+ +----+ +-----------------+

ethernet
We wanted to make a telnet session from an unix station on ethernet to the SUN.
This didnot work. On the CISCO we saw that on the serial interface there was a
connection with the X.25 network. But when we tried to start a telnet session
from the CISCO to the SUN, it just didnot work.
Mine questions are: a) how do you need to configure the CISCO to do this?
b) how do you need to configure the SUN to do this?
Here is what the CISCO show us (debug info and configurition):
