•
Waiting
. The router is trying to determine the identity of the
(backup) designated router by monitoring received hello packets.
The router is not allowed to elect a backup designated router or a
designated router until it transitions out of the waiting state. This
prevents unnecessary changes of the (backup) designated router.

Designated Router
. This router is the designated router on the
attached network. adjacencies are established to all other routers
attached to the network. The router must also originate a network
LSA for the network node. The network- LSA contains links to all
routers (including the designated router) attached to the network.

Backup Designated Router
. This router is the backup designated
router on the attached network. It is promoted to designated router
if the present designated router fails. The router establishes
adjacencies to all other routers attached to the network. The
backup designated router performs slightly different functions
during the flooding procedure, compared to the designated router.
