Thanks a lot Brian! I was wondering where the class maps are configured
on dialer ints.
Another question that I had was related to snapshot routing. If I
understand it correctly, during the active periods the routes are
exchanged from the server to the client router and if at the start of
active time the dialer int is not up, the line will be brought up.
But once the quiet period begins, the idle timeout period on the server
will kick in (say 60 seconds) and the int will go down. this will cause
the ospf adjacency to go down and the routes will be removed from the
routing table on both ends...so whats the point of the exercise? Or am I
misunderstanding the concept. The DocCD is highly unclear on this.
Thanks
Rohan

Rohan,
You are missing the map-class that should be bound to the dialer
string on the server side.
RB#sho run int dialer 1

Current configuration : 311 bytes

Subject: ppp callback with dialer ints
Hi,
i'm trying to configure PPP callback with dialer interfaces but it does
not seem to be working. It is working fine with legacy DDR config.
Configs
Client
====
RA#sh run int dialer1
Building configuration...
Current configuration : 244 bytes
!
interface Dialer1
ip address 11.0.0.1 255.255.255.0
encapsulation ppp
ip ospf cost 999
dialer pool 1
dialer remote-name RB
dialer idle-timeout 100
dialer string 11111
dialer-group 1
ppp callback request
ppp authentication chap
end
RA#
Server
=====
RB#sh run int dialer1
Building configuration...
Current configuration : 293 bytes
!
interface Dialer1
ip address 11.0.0.2 255.255.255.0
encapsulation ppp
ip ospf cost 999
dialer pool 1
dialer remote-name RA
dialer idle-timeout 100
dialer enable-timeout 20
dialer string 22222
dialer callback-secure
dialer-group 1
ppp callback accept
ppp authentication chap
end
RB#
=========
debug dialer on the server side shows that 'no callback configured for
RA'. I know that in legacy DDR a dialer class is required with
callback-server username, but how do I do the same with dialer int? How
do I apply a class to a dialer int?
Thanks
Rohan
