Field
Description
Neighbor State
The state of the virtual neighbor relationship. The OSPFv3 interface 
state can be any of these values:
• 
Down
. This is the initial interface state.The lower-level protocols 
indicated that the interface is unusable. Interface parameters are 
set to their initial values. All interface timers are disabled, and there 
are no adjacencies associated with the interface.
• 
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.
• 
Point-to-Point
. The interface is operational, and is connected to 
the virtual link. On entering this state the router attempts to form an 
adjacency with the neighboring router. The interface sends hello 
packets to the neighbor at every hello interval seconds.
• 
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.
• 
Other Designated Router
. The interface is connected to a 
broadcast or NBMA network on which other routers were selected 
to be the designated router and backup designated router. The 
router attempts to form adjacencies to both the designated router 
and the backup designated router.
State 
(continued on the next page)
The state of the interface. It takes one the following values:
• 
Down
. This is the initial interface state. The lower-level protocols 
indicated that the interface is unusable. Interface parameters are 
set to their initial values. All interface timers are disabled, and there 
are no adjacencies associated with the interface.
• 
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 waiting state. This prevents 
unnecessary changes of backup designated router.
• 
Point-to-Point
. The interface is operational, and is connected 
either to the virtual link. On entering this state the router attempts 
to form an adjacency with the neighboring router. hello packets are 
sent to the neighbor every hello interval seconds.
