Hi everyone,

Just a few more days until fun Day #1

I have a question about Dialer profiles. I am having some trouble with my
ISDN line staying down when using dialer profiles instead of the physical
BRI interface. It is not because of filtering problems because when using
the physical interface it works fine, but when I use dialer interfaces with
what I believe is the correct config:

calling router
R1#
interface Dialer0
  ip address 133.1.100.5 255.255.255.252
  no ip directed-broadcast
  encapsulation ppp
  ip ospf message-digest-key 1 md5 cisco
  ip ospf demand-circuit
  dialer remote-name router3
  dialer pool 1
  dialer idle-timeout 20
  dialer string 5552221
  dialer load-threshold 128 outbound
  dialer-group 1
  no peer neighbor-route
  pulse-time 0
  ppp authentication chap callin
  ppp multilink
end

called router
R2#
interface Dialer0
  ip address 133.1.100.6 255.255.255.252
  no ip directed-broadcast
  encapsulation ppp
  ip ospf message-digest-key 1 md5 cisco
  ip ospf demand-circuit
  dialer remote-name router5
  dialer pool 1
  dialer idle-timeout 20
  dialer string 5554441
  dialer load-threshold 128 outbound
  dialer-group 1
  no peer neighbor-route
  pulse-time 0
  ppp authentication chap
  ppp multilink
end

The line will not stay down and the cause is destination 224.0.0.5 . Can
you not use ip ospf demand circuit on a dialer interface?
Remember, when I take the dialer interfaces away and just use the physical
BRI interfaces, it works fine. Any thoughts?

Thanks,
David
