Hi group,
I am just entry in async dialup, sorry to ask the following simple
question:
-- I am setting the following lab scenario, I have a router "R26" and a
router "REMOTEGW":
R26 (Aux 0) -- (modem) ----------(PSTN)-------------- (modem) -- (Line tty
8) Remote
phone no 5413
phone no 5001
And I would like to setup routing by async dialup, I have tested at each
router by reverse telnet that the remote modems can be reached, by
"ATDT5001" & "ATDT5413"
The following is my two routers config, I cannot get it to be worked (I
cannot ping the other end)
1) R26
chat-script dial "" "ATZ&F" OK "ATDT 5413" TIMEOUT 60 CONNECT
interface Async65
ip address 192.168.20.1 255.255.255.0
encapsulation ppp
dialer in-band
dialer map ip 192.168.20.2 name REMOTEGW broadcast 5413
dialer-group 1
autodetect encapsulation ppp
async dynamic routing
async mode interactive
ppp authentication chap
!
line aux 0
script dialer dial
modem InOut
modem autoconfigure discovery
no exec
transport input all
speed 115200
flowcontrol hardware
2) REMOTEGW
chat-script dial "" "ATZ&F" OK "ATDT5001" TIMEOUT 60 CONNECT
interface Async8
ip address 192.168.20.2 255.255.255.0
no ip directed-broadcast
encapsulation ppp
dialer in-band
dialer map ip 192.168.20.1 name R26 broadcast 5001
dialer-group 1
autodetect encapsulation ppp
async dynamic routing
async mode interactive
ppp authentication chap
line 8
no exec
script dialer dial
modem InOut
modem autoconfigure discovery
transport input all
speed 115200
The following is my debug, you can see that even the async interface is up
(it takes aroung 30 secounds so I keep ping it), PING still not success.
REMOTEGW#p 192.168.20.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.20.1, timeout is 2 seconds:

Any insight about this? I find that the modem will ring three times before
response to the call, is it the fatal problem? Or I have to make the modem
to certain operation mode so that for async routing to work?
Thx a lot!
