Can you try it with 2 completely unrelated routes that don't have a summary
( /28 in your case ) that points to those network's.
It should require ALL routes to be gone.
See below...

The answer is #1. Either route going away will cause it to dial
immediately. I set it up briefly on a lab router here, so the output is a
bit long but you'll see what you want...

Hi EToker,
Thanks for your feedback. From your 2nd sentence, I can see that you choose
answer 2. I received quite a number of answers offline, they chose answer 1.
Has anyone tested this? I would really like to test it out on my lab, but my
ISDN simulator has not arrived yet. Can anyone confirm this? Thanks..

Hi,
It checks at least one valid route for the watched networks. It will not
trigger if at least one of the routes is still available.

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
