Hello All,
I've configured ip ospf demand-circuit on an ISDN connection and this
statement is supposed to supress the calls initiated by the Hello Packets.
Still my router keeps on dialing.
Does anybody know what the reason might be?
Thanks,

Got an OSPF demand circuit to work as advertised:

OSPF Router with ID (10.7.7.7) (Process ID 2
Its got something to do with the cost. try setting the ip opsf cost on the

Hi,
The answer is NO, you don't need to deny ospf as interesting traffic in the
ACL.
In fact , having read rfc 1793 (http://www.ietf.org/rfc/rfc1793.txt)which
explains demand ccts and I think that by doing this you will break the
demand cct feature. OSPF requires that initially the database
Hello,
Had a question on ip ospf demand-circuit?
For an isdn bri backup for 2 sites running ospf, in addition to the ip ospf
demand-circuit command on both the interfaces, is it necessary to configure:
#dialer-list 1 prot ip list 101
!
#access-list 101 deny ospf any any
#access-list 101 permit
The OSPF demand circuit command only needs to be placed on the router that
is dialing, unless the ISDN is active, r5 is not receiving hellos, or an LSA
refresh every 30 minutes so the dead timer on the LSAs would expire. This
is overcome with the OSPF demand circuit command. From the output
demand
circuit to come up? I don't see how it could simply be a
topology change since OSPF isn't aware of the IS-IS topology.
So, specifically, what is occurring? Perhaps I'm being dense
but I just don't see which mechanism is responsible for this.
Someone, please put me out of my misery
Okay, nevermind! I discovered what was occurring. I was
misunderstanding my own configuration. On a remote router I
was redistributing IS-IS into OSPF. So, when my local
interface--running IS-IS--went down, this triggered an LSA
update remotely, which in turn caused the OSPF demand
Hi Group,
When viewing CCIE power session presentation of Networkers 2000, I could not
understand why you could form route loop when using ospf demand circuit.
Here is the example given there:

Does anyone have a successful config for ospf demand-circuit
over ISDN, where the dialer profile is used ?
My config is as follows, but whenever I put ip ospf demand-circuit
on dialer interface 1 (of RA), the show ip ospf command will show it
not a ABR anymore and OSPF stop to work right away

You should be able to use this command on typically any router
that at mimimum has an aux port. A quick look on CCO for the command ip
