I would like to get our CGS 3 router to accept X25 calls for 2 addresses.
I was working on this when we upgraded from 8.2 to 9.0(1) today.
In the 8.2 config I had an X25 route phrase like this:
x25 route ^23421234567890 alias Null0
To be frank, I do not know if this does what I want, because I had not
tested it before the new PROMS arrived. However it is a bit academic,
as (from my experimentation) 9.0(1) will not accept the null interface
in an X25 route command. I get told "Must be running X.25 - Null0" -
fair enough, but 8.2 didn't complain!
What I would like to do is to set up the router to accept calls that
are addressed to an X121 number other than that applied to the serial
interfaces, I understood from the manual that this is what the "alias"
clause would do. But if I cannot give the null interface, what
interface should I use? What does the interface name mean when an
alias is specified? Is it for calls that come in that interface only,
or is the call sent back to that interface? Or does the call appear to
come from that interface?
In case anyone from Cisco says that I should ask them, I should say
that our local UK technical support people cannot help, and asking the
net seemed like the next quickest route. But in case anyone is
interested; it is my view that the manual (including the 9.0 manual)
is a little vague on this point.
