OSPF Neighbor Table

This table can be found by clicking Monitoring > Layer 3 Feature > OSPF Monitor > Browse OSPF Virtual
Neighbor 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.
