Greetings,

Hi guys, i need yr help on this weird problem that i have with my router connecting to tokyo.

This is what i got in my trace log after enable ppp negotiation debug,

CSC183_18_1#

5d06h: %LINK-3-UPDOWN: Interface BRI1/0:1, changed state to up

5d06h: %ISDN-6-CONNECT: Interface BRI1/0:1 is now connected to 0081352553055

I don't understand why i keep getting the TIMEout error, does anyone has any idea what causes it? Pls pardon me as i m new in dealing with CISCO router. Thanks for any help

Hello,

looking at your configurations, I can see that the dialer map on the router CSC180_18_2 points to the other router with the name CSC168_183_1 , while the configured hostname of that router is CSC183_18_1 :

hostname CSC183_18_1

username xxxxx password xxxxx

dialer map ip 192.168.252.180 name CSC180_18_2 0081352553055

hostname CSC180_18_2

username CSC183_18_1 password 0 SNKOAS-94

dialer map ip 192.168.252.183 name CSC168_183_1 0041940000000

--> this should be:

dialer map ip 192.168.252.183 name CSC183_18_1 0041940000000

or, if you want the router CSC183_18_1 to use the name CSC168_183_1 instead of its real name for CHAP authentication, add the following command to the configuration of BRI1/1 on router CSC183_18_1

ppp chap hostname CSC168_183_1

Hi georg, thanks for yr help. Let me check whether is this a typo mistakes. One things though, u sure have a sharp eyes....8)

Greetings,

Hi Georg, sorry that i have sent u the wrong config file from Tokyo side.

This should be the right one, as seen from the config file, the dialer map is pointing to the right CSC. I would like to find out the problem is originate from where? Tokyo or Sri Lanka? Can i tell it from the config file? Or do i need to turn on some debug command? Appreciate your help. Thanks

Georg Pauwen · ‎11-14-2003

Hello,

I am not sure if your access lists on the BRI interfaces are ok. Can you do a term mon (or logging console) when you are trying to connect through the ISDN line ? This way you can see if any traffic is blocked by an access list. You could, of course, also remove the access lists completely and see what happens.

Regards,

Georg

alpaje · ‎11-14-2003

Greetings,

Hi Georg, will try that. Thanks for your quick reply. Really appreciate that.

ashok_boin · ‎11-14-2003

Hi,

According to your O/P observing at CSC183_18_1 router, this router is sending OUTbound requests but no return from remote end whether ACCEPT or DENY of conf request param. So, please try the same command on other router to observe atleast, it's getting these packets, if it gets, why it's not giving response?

If problem still not resolved, then do "debug ip access-list 100" and "debug ip access-list 101" at remote router.

Regards...

Ashok.

With best regards...
Ashok

DANIE DU TOIT · ‎11-14-2003

Try:

dialer map ip 192.168.252.183 name CSC183_18_1 broadcast speed 56 01094112466655.

I have seen this symptom when you do not have a 64K end to end service

the lines

Mar 8 06:31:21: Cause i = 0x8783 - No route to destination

are coming from the local switch , are you sure your dial string is correct ?

alpaje · ‎11-18-2003

Greetings,

Hi deilert, thanks for replying. I have asked my Tokyo branch to check with their local router switch operator on this matter.

Still waiting for their investigation finding.
