I am trying to configure an ISDN line from Paris to Singapore.
The following configs are abstracts from both routers.
I included a log of a success connection and a failing connection.
Of course I cannot get the debug log from Singapore.
The configuration is fine because it works ONCE.
If you try again after the timeout and the releasing of the ISDN line you get
the following when attempting a telnet:
BR0/0:1 LCP: TIMEout: State REQsent
BR0/0:1 LCP: O CONFREQ [REQsent] id 90 len 31
BR0/0:1 LCP: AuthProto CHAP (0x0314C12404)
BR0/0:1 LCP: MagicNumber 0x31878D89 (0x050631878D89)
BR0/0:1 LCP: MRRU 1524 (0x110405F4)
BR0/0:1 LCP: EndpointDisc 1 ROUT_PARIS (0x130C01524F5554546543)
If then you just restart the router in Singapore you can then connect once
When we want to work for a long time we issue a never ending ping to the
router to keep the line open.
I have seen the same behaviour in a forum. Usually the "LCP:O CONFREQ" with
timeout is often pointed as a ISDN / SPEED Mismatch. But in this case I am more
in doubt with a handle release problem in IOS.
I know that version are quite old but do you have a workaround and can you point
me to the most recent firmware than could correct this.
