State
Current state of the neighbor, which can be:
• Down, indicating the initial state of the neighboring relationship.
• Init, indicating 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 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, indicating the bidirectional communication is available, and the router ID can be
obtained from the Hello packet sent by the neighbor router.
• Exstart, indicating the master and slave between the router and the neighbor and the initial
DD packet sequence number are determined for exchanging DD packets.
• Exchange, indicating the router sends DD packets to its neighbor to describe its LSDB.
• Loading, indicating the router sends an LSR packet to its neighbor, requesting the newest LSA.
• Full, indicating adjacency has been established between the router and its neighbor.

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

Configuration procedure
1. Configure IP addresses for interfaces and configure security zones (omitted).
2. Configuring OSPF basic functions.
# Configure Device A.
• Select Network > OSPF from the navigation tree of Device A.
• Select the Enable OSPF check box, as shown in the following figure.
