Or at least, that's what I think is happening. There doesn't appear to be a debug command for this, or to see if something is in the routing table.
I'm testing out this setup in Packet Tracer. I have 3 routers and a webserver
From left to right, you have: Webserver -> Router1 -> Router2 -> Router3
Router1 and Router2 can succesfully ping WebServer. Router3 cannot.
Router2 has a default gateway set, to send all not-recognized data through its serial interface to Router1.
ip route 0.0.0.0 0.0.0.0 Serial 0/0/1
Serial 0/0/1 being the connection to Router1
Router2 and Router3 have OSPF configured. From their "show run":
router ospf 1 log-adjacency-changes passive-interface Serial0/0/1 network 10.1.1.0 0.0.0.3 area 0 default-information originate !
router ospf 1 log-adjacency-changes network 10.1.1.0 0.0.0.3 area 0 passive-interface FastEthernet0/0 !
I was under the assumption that setting
default-information originate on Router2 would give Router3 the needed information. What's going wrong here?
The interfaces are up. Ip addresses are with mask-range, clock rate is set at correct end. I don't know what else to check.
EDIT: I was going to post a screenshot, but now it's working all of the sudden. I opened the PKT file, repositioned stuff so the labels would be clear, took the screenshot and then ran the test again, to see where the real-time analyzer said the mistake was. And it worked.
I'm sorry to have taken your time over this. I'm flabbergasted over this.
