Browse OSPF Neighbor Table
This table can be found in the OSPF Monitoring folder by clicking on the Browse OSPF Neighbor Table link. Routers
that are connected to the same area or segment become neighbors in that area. Neighbors are elected via the Hello protocol.
IP multicast is used to send out Hello packets to other routers on the segment. Routers become neighbors when they see
themselves listed in a Hello packet sent by another router on the same segment. In this way, two-way communication is
guaranteed to be possible between any two neighbor routers. This table displays OSPF neighbors of the Switch.
