RE: ISDN backup will not activate [7:25129]

2001-11-03 Thread Sivarajan Thiruvadi

hi

Check wheather u made backup interface configuration.
In case if u use serial as primary ,u have to mention BRIS as backup.
Hope I understood the question correctly.

Your making it too hard,  you don't need the dialer map but you do need a
dialer
string 1800111.  Your not telling the interface where to call.

Re: ISDN backup will not activate [7:25129]

Hello,

Try using the backup interface command under the serial interface.

If the serial 0 is the primary then use the following config

 interface Serial0
 description line to 2522_router
 ip address 170.17.1.2 255.255.0.0
backup interface bri 0
backup delay 5 25 (it will wait 5 sec before activating the backup line.
Upon restoring of primary line, backup line will remaint active for 25 sec.)
 no fair-queue

Try this.

Faisal

Re: ISDN backup will not activate [7:25129]

2001-11-02 Thread John Neiberger

What are the results of show int bri0 and show isdn status?  That might
alert you to the problem.  If you've posted the entire config then you
definitely are missing at least one very important thing.

Look at the results of that output and let us know if the router is
even talking to the ISDN switch at the telco.  (hint hint)  :-)

Where's the phone number to dial?  I've always used a phone number after

You have no dial string and you also need to tell the router what interface
you want backed up or use a floating static.

Re: ISDN backup will not activate [7:25129]

2001-11-02 Thread EA Louie

I've seen the other replies to you post, and I'll give you a few other
pieces of input.  By the way, you really didn't give us any indication of
what you saw as the output from the router - I'll just assume that you saw
nothing.

1.  From the configuration, it is not obvious what kind of ISDN switch
you're using.  Do you know if you need to add a statement to define the
switch type?  (I'd guess yes, unless the rules changed in 12.2)

2.  Someone else indicated that you need to check the ISDN status using the
appropriate show command.  You'll learn something from doing that check.
Mostly, you'll learn how to read the status of the ISDN circuit, and what
the different fields indicate on the results of the show isdn status
command.  Learning the debug commands (debug isdn q921, debug isdn q931) are
also valuable tools.  Learn to use them to diagnose a problem.

3.  Look at the purpose of the dialer map statement.  Someone else indicated
that you need to configure a destination phone number for that.  I agree
with that indication.  Paris doesn't know what number to dial to reach
New_York_City.

4.  Someone suggested using backup-interface.  I'd counsel you NOT to go
down that road until you have the point-to-point ISDN configuration stable
and it's coming up when you want it to.

5.  Another person suggested that you add an administrative distance  to
your static route.  That would be a good idea.  When you do that, your ISDN
circuit will come up only when the route for the serial link goes away
(assuming that it's the only route to the other router)

6.  Some switches prefer/require that you suffix the dialing numbers to the
SPID assignments.  Learn which switches need that kind of input.

7.  What other resources have you used to learn configuration of ISDN?
There are different layers of ISDN configuration.  They are, in order of
bottom to top:
a.  the ISDN physical connection itself (S/T interfaces require NT-1's or a
simulator that has an S/T interface, U interfaces have a built-in NT-1)
Cisco 2500 series routers (except the 2524/2525) have an S/T interface.  The
2524/2525 has two flavors of modular BRI, S/T or U.  Cisco 4000 series NP-4B
and NP-8B have S/T interfaces.  I'm not sure about the 26/3600 series, but
I'm sure someone else on the list does know and might be willing to share
that info.
b.  ISDN interface establishing communication with the ISDN switch (q921
signalling  - requires the correct ISDN switch type configured and the
proper physical connection)
c.  ISDN interface obtaining TEI (q931 signalling-requires the ISDN SPIDs
configured properly)
d.  triggering the interface to dial (either IP or backup-interface or
snapshot routing, requires the dialer-map and dialer-lists configured
properly)
e.  encapsulation negotiation (ppp-requires both routers have a common
encapsulation)
f.  authentication (chap-requires username/passwords used in the dialer-map
statements match on both routers)
g.  IP routing (static or dynamic routes) over the interface (requires
routing protocol including static to route to the correct destinations via
the BRI interfaces).
h.  establishing multilink (requires the dialer-load statement)

8.  Extraneous commands in a BRI configuration sometimes spell disaster, so
take out anything that you don't absolutely need from a basic's perspective.

Otherwise, your configuration is a good start.  Unfortuately, incomplete BRI
configurations don't work, and don't give you any indication of why they
don't work.

I'll refer you to a very valuable resource, which I still use when I get
stuck on an ISDN configuration.  It's Cisco's TAC page for ISDN Technology:
http://www.cisco.com/pcgi-bin/Support/PSP/psp_view.pl?p=Internetworking:ISDN
(watch the URL wrap)

Here's a page with a very basic configuration that you can learn from, step
by step:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/dial
ts_c/dtsprt3/dcdbri.htm (watch the URL wrap)

ISDN is a very complex configuration until you've mastered the basics, which
means understanding the different layers of BRI configuration.  I'd suggest
that you study these pages, and then if it still doesn't work, c'mon back
and post the configurations from both routers and the results of some of the
show commands that you'll learn from reading the basic's pages.

Good luck in your studies, and let us know what you learn about ISDN.
