And "sh ip ospf stat" will show you activity of OSPF - remember that every
change in OSPF
topology can trigger dialer.

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,

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 shoul
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 of

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.

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.

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

All,
I have a question in regardds to using the
ospf demand-circuit.
If you are using ospf demand circuit across an ISDN
line and do not want it to dial when external routes
that were redistributed into OSPF flap how is this
done?
