Field Descri
p
tion
State
Current state of the neighbor:
• Down—The initial state of the neighboring relationship.
• Init—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
that the router receives no information from the neighbor, but it still attempts to
contact the neighbor.
• 2-way—The bidirectional communication is available, and the router ID can be
obtained from the Hello packet sent by the neighbor router.
• Exstart—The master and slave between the router and the neighbor and the
initial DD packet sequence number are determined for exchanging DD packets.
• Exchange—The router sends DD packets to its neighbor to describe its LSDB.
• Loading—The router sends an LSR packet to its neighbor, requesting the newest
LSA.
• Full—Adjacency has been established between the router and its neighbor.
OSPF configuration example
In this example, Device A is the LB module.
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.

Configuring Device A
1. Configure IP addresses for interfaces. (Details not shown.)
2. Enable OSPF:
a. Select Network > OSPF from the navigation tree of Device A.
b. Select the Enable OSPF box.
