Configure R1-R3, R3 will callback R1 through tacacs+
authentication and authorization.
Config on R1:
hostname r1
!
!
username r3 password 0 CISCO
interface BRI0
ip address 192.168.45.4 255.255.255.0
encapsulation ppp
dialer map ip 192.168.45.5 name r3 broadcast
4082222222
dialer-group 1
isdn switch-type basic-ni
isdn spid1 40811111111
isdn spid2 40811111112
ppp callback request
ppp authentication chap
ppp multilink
multilink min-links 2
dialer-list 1 protocol ip permit
Config on R3:
hostname r3

aaa authentication ppp default group tacacs+ local
aaa authorization network default group tacacs+ local
!
username r1 callback-dialstring 4081111111 password 0

ppp callback accept
ppp authentication chap
ppp multilink

tacacs-server host 192.168.1.2 key cisco
On tacacs+ server, I configured user r1 with
callback-string, Assigned by dialup client, PPP IP,
PPP LCP and PPP multilink
R3 did callback, but disconnect immediately. I got:
01:13:45: %ISDN-6-DISCONNECT: Interface BRI0:1
disconnected from 4081111111 r1,
call lasted 2 seconds
01:13:45: %LINK-3-UPDOWN: Interface BRI0:1, changed
state to down
Any suggestion?
