When I tried to configure callback with tacacs, when I
use legacy DDR on client side, dialer profile on
server side.
My config:
Client:
interface BRI0
ip address 145.45.45.4 255.255.255.240
encapsulation ppp
ip ospf authentication message-digest
ip ospf message-digest-key 1 md5 7 110A1016141D
dialer idle-timeout 180
dialer map ip 150.50.12.0 name Rack06R5 broadcast
4082222222
dialer map ip 145.45.45.5 name Rack06R5 broadcast
4082222222
dialer hold-queue 20
dialer load-threshold 128 either
dialer watch-group 1
dialer-group 1
isdn switch-type basic-ni
isdn spid1 40811111111 4081111111
isdn spid2 40811111112 4081111111
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
no peer default ip address
ppp callback request
ppp authentication chap callin
ppp chap hostname router4
ppp chap password 7 14141B180F0B
ppp multilink
Server Side:
aaa new-model
aaa authentication ppp PPPCALLBACK group tacacs+
aaa authorization network PPPCALLBACK group tacacs+
interface BRI0
no ip address
encapsulation ppp
dialer rotary-group 1
isdn switch-type basic-ni
isdn spid1 40822222221 4082222222
isdn spid2 40822222222 4082222222
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
ppp authentication chap callin PPPCALLBACK
!
interface Dialer1
ip address 145.45.45.5 255.255.255.240
encapsulation ppp
ip ospf authentication message-digest
ip ospf message-digest-key 1 md5 7 01100F175804
ip ospf demand-circuit
dialer in-band
dialer aaa
dialer idle-timeout 180
dialer enable-timeout 5
dialer hold-queue 20
dialer load-threshold 128 either
dialer-group 1
no peer default ip address
ppp callback accept
ppp authentication chap callin PPPCALLBACK
ppp authorization PPPCALLBACK
ppp multilink
But I got the following output from debug dialer on
server side:
00:40:49: BR0:1 DDR: Authenticated host router4 with
no matching dialer map

00:40:58: Di1: Session free, 1194
00:40:58: : 0 packets unqueued and discarded
00:40:58: BR0:1 DDR: disconnecting call
-----------------------------
Server tried to dial client, but it disconnect right
away. before I added dialer-group 1, callback
negotiated but callback server do not disconnect.
