Table 150. Advanced OSPFv3 Virtual Link Configuration Field Neighbor State Description 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. Configure OSPF and OSPFv3 413 User Manual
