Hello everyone,
I am configuring an ISDN connection but I am having one strange problem: the first connection works (I can ping the other side) but the second attempt to connect (after manual disconnect) wont.
Here is my confing:
ISDNA-FRROUTERC:
hostname ISDNA-FRROUTERC
isdn switch-type basic-net3
interface BRI0
description local nr 21, remote nr 20
ip address 192.168.0.13 255.255.255.252
dialer idle-timeout 3600
dialer map ip 192.168.0.14 name ISDNB broadcast 20
dialer-group 1
isdn switch-type basic-net3
!
dialer-list 1 protocol ip permit
ISDNB router conf:
hostname ISDNB
isdn switch-type basic-net3
interface BRI0
ip address 192.168.0.14 255.255.255.252
encapsulation hdlc
dialer idle-timeout 3600
dialer map ip 192.168.0.13 name ISDNA-FRROUTERC broadcast 21
dialer-group 1
isdn switch-type basic-net3
!
dialer-list 1 protocol ip permit
The ISDN switch doesn't require SPIDS.
Now, some info on the
sh isdn cmd:
ISDNB#sh isdn status
Global ISDN Switchtype = basic-net3

dsl 0, interface ISDN Switchtype = basic-net3

Well everything checks fine... but I can't ping from one side to the other!!!
Any ideas? Guidance??
Thanks!
