11.4.3.8 Configuring OSPF Neighbor
This panel displays the OSPF neighbor configuration for a selected neighbor ID. When a particular
neighbor ID is specified, detailed information about a neighbor is given. The information below will only be
displayed if OSPF is enabled and the interface ha s a neighbor. The IP address is the IP address of the
neighbor.
Selection Criteria
Slot/Port - Selects the interface fo r which data is to be displayed or configured. Slot 0 is the base unit.
Neighbor IP Address - Selects the IP Address of the neigh bor fo r which data is to be displayed.
Non-Configurable Da ta
Router ID - A 32 bit integer in dotted decimal format that identifies the neighbor router.
Options - The optional OS PF capabilities supported by the neighbor. The neighbor's optional OSPF
capabilities are also listed in its Hello packets. This enables re ceived Hello Packets to be rejected
(i.e., neighbor relationships will not even start to form) if there is a mismatch in certain cru cial OSPF
capabilities.
Router Priority - Display s the OSPF priority for the sp ecified neighbor. Th e priority of a neighbor is a
priority integer from 0 to 255. A value of '0' indicates that the router is not eligible to become the
designated router on this network.
State - The state of a neighbor can be the following:
• Down - This is the initial state of a neighbor conversat ion. It indicates that there has be en no
recent information received from the neighbo r. On NBMA networks, Hello packets may still be
sent to "Down" neighbors, although at a reduced frequency.
• Attempt - Thi s state is o nly valid for neig hbors attache d to NBMA networks. It indicate s that
no recent information has been re ceived from the neighbor, but that a more concerted effort
should be made to contact the neighbor. This is done by sending the neighbor Hello packets
at intervals of Hello Interval.
