Hi guys,
I tried to connect R1 to R2 using only one ISDN number (from the first B channe
l dialed to the 2nd B channel)
The configuration:
R1
interface BRI0
ip address 196.1.1.1 255.255.255.0
encapsulation ppp
dialer map ip 196.1.1.2 name R2 broadcast 25500598:2
dialer-group 1
ppp authentication chap
R2
interface BRI0
ip address 196.1.1.2 255.255.255.0
encapsulation ppp
dialer map ip 196.1.1.1 name R1 broadcast 25500598:1
dialer-group 1
ppp authentication chap
When I triggered from R1 using ping, it worked. The ISDN is up, B Channel 1 fro
m R1 dial to B Channel 2 in R2
But when I tried to trigger from R2, the debug result showed layer 3 has active
but the ping failed
R2#ping 196.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 196.1.1.1, timeout is 2 seconds:

Total Allocated ISDN CCBs = 2
In fact, the ISDN connection was not establish, even layer 3 status from show i
sdn status command showed 2 active layer 3 calls
Any suggestion?
