What's your config? I use PPP multilink with the dialer string command
(no "dialer map ip" command) without problems (well, not usually relating
to that ;-) But I'm not doing call-back. Can you get it to work without
call-back?

Subject: PPP multilink problems and more [7:42264]
Hi;
I am doing a lab scenario that is looking for a ISDN PPP Multilink with
callback connection between two routers(lab17). Anyway the lab specifies
not
to use the dialer map command on the calling router but on the callback
router its ok. I used the "dialer string" command and can get the router
to
call and be called back ok. The problem is without the "dialer map ip"
command I get encapsulation failed when I do a "debug ip packet" and this
in
turn causes the OSPF hellos on the BRI0 interface to fail. I have looked
high and low on both this site and Cisco for a solution but couldn't find
one. The labs solution called for the "dialer string" command I just can't
make it work. If I remove the dialer string command and replace it with a
dialer map command my OSPF comes up and then the demand circuit works and
suppresses the hellos. Also on the lab they call for both BRI channels to
come up. I am using the "PPP multilink" and "dialer load-threshold 1"
command to no avail. a "show ppp multilink" shows only the BRI0:1 coming
up.
My only thought is that my ISDN simulator(Adtran550) doesn't support it,
but
i know they use this box in the real CCIE labs. Is there something that
needs to be configured on the Adtran or is there something else I am
missing? I am starting one of the CCIE practical studies lab(Skynet)
tonight
so any quick help would be good if not I move on.Thanks.
