   Hello, Seonghui.
  Your 2) answer is right. Both routes need to disappear from routing
table in order ISDN to initiate a call.
 
  As far as any of the IP destinations mentioned in watch-list will be
available, ISDN will be inactive since it will asume that disapearance
of some routes is due to routing protocol problems.

Subject: question on dialer watch-list

Hi Group,
 
Sorry to ask this question without testing it. I am still waiting for my
ISDN simulator...
 
I was going thru a dialer watch-list scenario and suddenly this question
poped up in my head. If I have more than one network in my dialer
watch-list to be 'watched' and they are in the same watch-list group 1,
will the ISDN trigger based on:-
 
1) either route lost from the routing table?
2) Or both routes must dissappear from the routing table before the ISDN
initiate a call?
3) or will it based on only the first statement in the dialer
watch-list? second statement is ignored?
 
Below is the config:
 
interface BRI1/0
 ip address 172.16.20.2 255.255.255.0
 encapsulation ppp
 shutdown
 dialer map ip 172.16.200.0 name r5 broadcast 77128888
 dialer map ip 172.16.100.0 name r5 broadcast 77128888
 dialer map ip 172.16.20.5 name r5 broadcast 77128888
 dialer watch-group 1
 isdn switch-type basic-net3
 ppp authentication chap
!
 
dialer watch-list 1 ip 172.16.200.0 255.255.255.128
dialer watch-list 1 ip 172.16.100.0 255.255.255.128
 
I tried searching the doc cd but the example is only for watching 1
route.
 
Thanks and regards - SH
