Hi every body.
Let say we have a following scenario
I just configured router with ospf
According to my book, router will wait for " dead interval time" before concluding that it is DR.
How about if i just take the router out of box, configure it for ospf without connecting its interfaces to any switch or network. So we have just stand alone router configured with ospf . Will router still wait for dead interval time and conclude it is indeed a DR.
Thanks a lot.
I think we need to be very careful about the question from the original poster. The question asks if you take a router fresh out of the box and configure it for OSPF. If the interface is not connected to anything, then on an IOS router the interface will be line protocol down and in that case OSPF will not be running on the interface and there will be no election.
But the response from Jorgemario is wrong :(
The election of DR does not depend on having neighbors on the multiaccess segment. When the inteface on the IOS router does go to state of protocol up, and with OSPF configured on the interface then the router will initiate the process of election. It will still wait for the interval before it completes the election. But there will be an election. I have seen it many times where there is an Ethernet interface on a router that has no OSPF neighbors and that router is the DR for the segment.
