Robert,
You are correct. Think of it this way, there first has to be a table
to populate before OSPF can populate it, so when the startup configuration
is read, the router takes the ip address statements from the interfaces,
along with any static routes, and creates the initial routing table. Now
there is something for OSPF to populate. Also, the config file must be read
to determine which interfaces will participate in the OSPF process, so the
"connected routes" must be known before the OSPF state-machine is started.

Subject: OSPF Startup? [7:49493]
Can someone clarify this for me?
During OSPF Start up when is the DR/BDR election done? The BSCN books
states it is in this order:
- Routing Table is Generated
Down State
Init State
2way State (bidirection communication established)
- DR/BDR Election
ExStart State (DR/BDR election done)
Full State
So the routing table is first populated for each router, then the DR and BDR
are elected?
Thanks
