thing with ppp multilink is the following

Both end times ie, load-thres, dialer-timeouts have to be exactly the same.
Also, I found that u need ppp multilink on the dialers and bri ints and
ensure both sides are the same.

Maybe this will help.

Subject: Help needed on ISDN PPP Multilink [7:58474]


Hi, friends.

I have one ISDN issue which make me quite headache, ok, I can call each
channel up (through dialer map or isdn call interface command) separately
without problem, which the problem is when I try to leverage PPP multilink
to bundle two channels in case of load-threshold events was fired, the
calling router did try to establish the second channel, and it's connected,
and the second call was CONNECTED for couple of seconds, then disconnected,
without error messages.

I opened a ticket with Cisco and our ISP, but no positive answer yet, any
help.

The following attachment is the debug (isdn, q931, ppp) from the called
router, as well as the config-file from the calling router, and the
configuration of called router is very similar with the calling router,
thanks.
