HI,
The question is from the book - CCIE Lab Pratice kit- from MCGrawHill,
authored by Michael Staterlee.
Whats strange is that they specify this in the question, however
mysteriously omit the mention of this in the solution.
Also since the ISDN link is running RIP, I guess dilaer watch would not be
an optimum solution.
Not sure really if it is doable, just wanted to be make sure by posting the
question.
Thanks,
Mohit.

It would seem to me that using dialer watch would be what you would want to
use in this scenario
since you cannot use backup interface, but the waiting 5 seconds after the
primary link is lost
is a bit confusing. Dialer watch only has an initial timeout that can be
set.
Are you sure the question is correct?

HI John,
Thanks for your reply.
Sorry forgot to mention that the question also specifically states that you
should not use backup interface command.
Hence the confusion, how can you tell ISDN to wait for 5 seconds after the
primary is down??
I tried a lot of timers, nothing worked :)
Any further ideas??
Smiles,
Mohit.

Hello,
I know that the active and quiet time works as follows you configure it in
terms of minutes, and the active time tells the router when to exchange
routing info, if you specify 5 then the link would come up every 5 minutes
for as long as the quiet time you specify. So I dont think that these
numbers would apply. I think you would also need to use the backup
interface method, you can specify the the time by using the backup delay.
Although I havent tested this it would be interesting to try.
As far as the demand circuit, it doesnt matter which side you put it on, you
only need it on one side.
Sincerely,
Matijevic
