Hi All,

Have an issue here with two routers over ISDN. I am pretty sure that I
cant communicate between the two because the link is not being brought
up properly. I see that after 110 seconds, the link dies. I debug ppp
authent, and I see the following.


00:16:37: %ISDN-6-LAYER2UP: Layer 2 for Interface BR0, TEI 66 changed to
up
00:16:37: %DIALER-6-BIND: Interface BRI0:2 bound to profile Diale
00:16:37: %LINK-3-UPDOWN: Interface BRI0:2, changed state to up
00:16:37: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up
00:16:37: %DIALER-6-BIND: Interface BRI0:1 bound to profile Dialer0
00:16:43: %ISDN-6-CONNECT: Interface BRI0:1 is now connected to
111111111
