Where are you using dialer profiles? I see an interface configured and a
rotary-group.  No dialer profiles...

read the sectin on "new dialer profile model"

Stephen

example of a profile
interface dialer0
 ip unnumbered loopback0
 encapsulation ppp
 dialer remote-name Remote0
 dialer pool 1
 dialer string 5551212
 dialer-group 1
 
interface dialer1
 ip unnumbered loopback0
 encapsulation ppp
 dialer remote-name Remote1
 dialer pool 2
 dialer string 5551234
 dialer-group 1
 
interface bri 0
 encapsulation PPP
 dialer pool-member 1
 dialer pool-member 2
 ppp authentication chap

NO im suggesting that you can have PPP authentication on the BRI interface
and not have a dialer interface. Look at my configs below:


Router R1 has ppp authentication on BRI interface only, no dialer interface
is used:


Interface bri0/0
ip address x.x.x.x x.x.x.x.
encap ppp
isnd spid1 xxxx xxxxxxx
isdn spid2 xxxx xxxxxxx
dialer idle-timeout 90
dialer map ip 196/1/1/1/1 name routerA
dialer-group 1
ppp authenticaton chap
ppp multi

!
no ip classless
dialer-list 1 protocol ip permit
.
Router with dialer interface providing same function:

interface BRI0
 description ISDN configuration interface
 no ip address
 no ip directed-broadcast
 encapsulation ppp
 dialer rotary-group 0
 isdn switch-type basic-ni
 isdn twait-disable
 isdn spid1 xxxxxxxxxxxx
 isdn spid2 xxxxxxxxxxxx
!
interface Dialer0
 description Dialer interface for SPID #
 ip address x.x.x.x.x.x.x.x
 no ip directed-broadcast
 encapsulation ppp
 dialer in-band
 dialer idle-timeout 600
 dialer string xxxxxxxxxx
 dialer hold-queue 10
 dialer load-threshold 2 either
 dialer-group 1
 ppp authentication chap callin
 ppp chap hostname xxxxxxx
 ppp chap password xxxxxxx
 ppp pap sent-username xxxxxxx
 ppp multilink
!

So here we have 2 configs both providing the option to do authentication and
dial out
