Chapter 14 Routing OSPF Status Process Summary This table lists all processes that exist on the device. This includes its Router id, number of areas configured, number of normal areas, number of stub areas, and number of nssa areas. Process Id—Unique identifier for a OSPF Process. Router Id—Unique identifier of the router in the AS. Domain Id—Domain Identifier, will be set when VRF is associated with this OSPF Process. No.
Chapter 14 Routing OSPF Status Area OSPF Area ID—Unique identifier of the area. Auth Type—The authentication type specified for an area. Additional authentication types may be assigned locally on a per Area basis. Import AS Extern—The area's support for importing AS external link-state advertisements. SPF Runs—The number of times that the intra-area route table has been calculated using this area's link-state database.
Chapter 14 Routing OSPF Status Interface The Interface tab displays three areas: Interface, Interface Metric and Virtual Interface. Interface Addressless Interface—Differentiates the addressless interfaces from the addressed interfaces. When the value is set to zero, it signifies that the interface has an IP address. Interface IP Address—The IP address of the OSPF interface. Interface Area ID—Unique identifier of the area to which the interface connects. Area ID 0.0.0.0 is used for the OSPF backbone.
Chapter 14 Routing OSPF Status Interface State—The OSPF Interface State. Designated Router—The IP Address of the Designated Router. Backup Designated router—The IP Address of the Backup Designated Router. Interface Events—The number of times this OSPF interface has changed its state, or an error has occurred. Interface Metric Addressless Interface—Differentiates the addressless interfaces from the addressed interfaces. When the value is set to zero, it signifies that the interface has an IP address.
Chapter 14 Routing OSPF Status Vir Interface State—Signifies the OSPF virtual interface states. Vir Interface Events—The number of state changes or error events on this virtual link. Vir Interface Status—Displays the validity or invalidity of the entry. Setting it to 'invalid' has the effect of rendering it inoperative. Neighbor The Neighbor tab displays two areas: Neighbor and Virtual Neighbor. Neighbor Neighbor IP Address—The IP address of this Neighbor.
Chapter 14 Routing OSPF Status Virtual Neighbor Vir Nbr Area—The identifier of the Transit Area. Vir Nbr Router ID—An integer that uniquely identifies the neighboring router in the Autonomous System. Vir Nbr IPAddr—The IP address that is used by this Virtual Neighbor. Vir Nbr Options—A bit map corresponding to the neighbor's options field. Thus, Bit 1, if set, indicates that the neighbor supports Type of Service Routing; if zero, no metrics other than TOS 0 are in use by the neighbor.
Chapter 14 Routing OSPF Status Host The Host tab displays a single area namely, Hosts. Hosts Host TOS—The Type of Service of the route being configured. Host IP Address—The IP Address of the Host Host Metric—The Metric to be advertised. Host Status—Displays the validity or invalidity of the entry. When this value is set to invalid, it has the effect of rendering it inoperative. Cisco 12000/10720 v3.
