IP Address IP address of the neighbor router
DR Priority DR priority of the neighbor router
State
Current state of the neighbor, which can be:
• Down—Indicates that the initial state of the neighboring relationship.
• Init—Indicates that a Hello packet is received from the neighbor before the
neighbor is down, but it does not contain the router ID. In such cases,
bidirectional communication is not available.
• Attempt—Which is available on the neighbor of an NBMA network only. It
indicates the router receives no information from the neighbor, but it still attempts
to contact the neighbor.
• 2-way—Indicates that the bidirectional communication is available, and the
router ID can be obtained from the Hello packet sent by the neighbor router.
• Exstart—Indicates that the master and slave between the router and the neighbor
and the initial DD packet sequence number are determined for exchanging DD
packets.
• Exchange—Indicates that the router sends DD packets to its neighbor to describe
its LSDB.
• Loading—Indicates that the router sends an LSR packet to its neighbor, requesting
the newest LSA.
• Full—Indicates that adjacency has been established between the router and its

OSPF configuration example in the web interface
Network requirements
• All the devices run OSPF, and the AS is divided into three areas.
• SecPath and Device A act as ABRs to forward routes between areas.
• Configure Area 1 as an NSSA area, and configure Device B as an ASBR to redistribute static routes
into the AS.
