Hi,
Thanks for getting back to me. I found an example of what you were saying
at this link:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_
c/dcdbakdw.htm
In this example, there are 3 routes listed in the dialer watch-list,
3.x.x.x, 4.x.x.x, and 5.x.x.x but there's only 2 dialer map statements - 1
for the ip addr of the other side of the dialup link and 1 for 3.x.x.x
But, this is what I don't really understand. Why the dialer map for 3.x.x.x
and not either 4.x.x.x or 5.x.x.x ?
Would it work just as well if nets 4.x.x.x or 5.x.x.x were used instead or
did it have to be 3.x.x.x ?
Also, I have another topology I'm wondering about.
Suppose you have Frame Relay hub and spoke topology where r1 is the hub and
is using a multipoint interface to reach r2, r3 and r4. All the routers
have bri interfaces and I want to have r1 using dialer watch call any of the
3 spokes if their f/r interface goes down. Assume each spoke router has a
loopback interface such as 2.x.x.x, 3.x.x.x, and 4.x.x.x and these are
exchanged via the routing protocol.
In other words, I want r1 to call r2 if 2.x.x.x is no longer in the route
table or call r3 if 3.x.x.x is no longer in the route table or call r4 if
4.x.x.x is no longer in the route table. In this case, do I need 3 dialer
map statements - 1 pointing to each of the spoke routers? And, are there
any other things I need to do to make this work?
Thank you so much. dt
