Elementary Problem!

[Rohit Gupta <[e-mail]>]

What happens when two OSPF speaking routers are
simultaneously switched on a broadcast network? Both
of them will put the DR and the BDR as Zero in their
HELLO packets.

They will both start with Neighbor Down state and
Interface down state. Once the Interface will come up
both will go to Waiting state. Now when they recieve
the HELLO message listiing each other they will reach
the 2-Way state.

What happens after that is not clear to me from the
RFC. How does the DR and BDR get elected? DO we wait
for the Wait timer to get expired?

The scenario is clear to me when one of them has
already elected a DR and a BDR. What is not clear to
me is when none of them have elected a DR and BDR.

Please help!

Regards,
Rohit
