ISDN between cisco 770 and 760

tomrubbens
Level 1
Level 1

have 2 cisco routers. One cisco 770 and one cisco 760. I want to use

a ISDN connection between the two. but with my current confirguration

only the cisco 760 can open the connection. When the cisco 770 tries to

open te connection he says no password found.

current config of the cisco 770 (t770):

set system t770

set multidest on

set ppp auth in chap

set ppp secret host

cd lan

set ip address 172.24.28.245

set ip netmask 255.255.252.0

set ip routing on

set ip rip update periodic

set user r760

set ppp auth out chap

set ppp secret client

set bridging off

set ip address 10.10.10.1

set ip netmask 255.255.255.0

set ip routing on

set ip rip update demand

set ip route destination 0.0.0.0 gateway 10.10.10.2

set ip rip version 1

set 1 number 051555555

set timeout 360

set active

reboot

current config cisco 760 (r760):

set system r760

set multidestination on

cd LAN

set ip address 192.168.1.1

set ip netmask 255.255.255.0

set ip routing on

set ip rip update periodic

set user t770

set ppp password client

set ppp secret client

set ip address 10.10.10.2

set ip netmask 255.255.255.0 set ip routing on

set ip rip update demand

set ip route destination 0.0.0.0/0 gateway 10.10.10.1

set number 051444444

set timeout 360

set active

reboot

everywhere i set a password i use the same password.

i also compared the two config and made one with all the command in the

2 above config both that wasn't any help

with the above config r760 can open connection to t770, but t770 can

not open the connection to r760 if it's not already active. always

receive the error 'no password found' and then he disconnects.

does anyone know why that happens?

kindest regards,

Tom

I reviewed your configuration it seems to be fine expect I miss the line "set ppp password client" on your r770 router. Review your r770 config and try again!

HTH

"set ppp password client" is set on r770 but not on the t770 as i see now. i'll try it after my lunchbreak ;)

thxs for the fast response

I see what you mean. i don't set the password on r770, only on the user setting.. i'l try to correct it and see if it works

I added the password but without success. To make sure the password is set i have set each password i could to the same password. in this example i used cisco.

these are my 2 configs then:

R760:

set system r760

set multidestination on

set ppp password host

cisco

cisco

set ppp secret host

cisco

cisco

cd LAN

set ip address 192.168.1.1

set ip netmask 255.255.255.0

set ip routing on

set ip rip update periodic

set user t770

set ppp password client

cisco

cisco

set ppp secret client

cisco

cisco

set ip address 10.10.10.2

set ip netmask 255.255.255.0

set ip routing on

set ip rip update demand

set ip route destination 0.0.0.0/0 gateway 10.10.10.1

set ip rip version 1

set 1 number 55555555

set timeout 20

set active

reboot

T770:

set system t770

set multidest on

set ppp auth in chap

set ppp password host

cisco

cisco

set ppp secret host

cisco

cisco

cd lan

set ip address 172.24.28.245

set ip netmask 255.255.252.0

set ip routing on

set ip rip update periodic

set user r760

set ppp auth out chap

set ppp password client

cisco

cisco

set ppp secret client

cisco

cisco

set bridging off

set ip address 10.10.10.1

set ip netmask 255.255.255.0

set ip routing on

set ip rip update demand

set ip route destination 0.0.0.0 gateway 10.10.10.2

set ip rip version 1

set 1 number 44444444

set timeout 20

set active

reboot

again it works to ping from R760 to T770:

r760> ping 10.10.10.1

Start sending: 01/01/1995 00:04:31 L05 0 555555555 Outgoing Call Initiate

d

r760> 01/01/1995 00:04:33 L08 1 55555555 Call Connected

r760> 01/01/1995 00:04:33 Connection 2 Add Link 1 Channel 1

r760> round trip time is 3080 msec.

but a ping from t770 to r760 does not initiate the call (that ping only works if r760 allready initiated the call):

t770> ping 10.10.10.2

Start sending: 01/01/1995 00:01:14 L05 0 444444444 Outgoing Call Initiate

d

t770> 01/01/1995 00:01:15 L08 1 444444444 Call Connected

t770> 01/01/1995 00:01:15 L60 1 Password Not Found

t770> 01/01/1995 00:01:16 L13 1 Disconnecting Call

t770> 01/01/1995 00:01:16 L27 1 Disconnected

i don't know what to do more. I think all passwords are set correctly.

Is there someone who has an idea? maybe it's just the difference between the types of routers.

anyone?

thanks.

I still haven't found the solution... Anyone who has a clou?

otherwise i'll work with this configuration and make sure the r760 initialises th connection.
