1. where is your ospf router definition?
2. for async interfaces, I use dialer profiles with ospf demmand circuit.
I do this because it seems like async interfaces don't want to spoof
properly and when the line drops it triggers a LSA which in turn, brings the
line back up.
3. since Ospf demmand circuits are triggerd by LSA's a good trouleshooting
procedure is to do a debug LSA-generation to see the timing of the LSA in
relationship to other events (like primary link failure), and then find the
LSA that was created in the OSPF database. I get good results with this.
Often I find another routing protocol is feeding back or advertising
connected networks into OSPF, causing OSPF to generate type 5's for the DDR
link.
HTH,

Subject: Async interface triggered by 224.0.0.5 using ip ospf demand
circuit
hi,
I have some problem with the ip ospf demand circuit, async interface is
triggered by the hello packet of ospf.
clearify someone what i am missing.
i am attacing the configuration and debug.
thanks in advance,
