When two routers attached to a network both attempt to become designated router, the one with the highest router priority takes precedence. A router whose router priority is set to 0 is ineligible to become the designated router on the attached network.

The router ID of the designated router that advertises link state for the network. The router ID of the backup designated router that becomes the designated router upon failure of the current designated router. The tag process ID can be used to identify multiple IS-IS processes by providing a meaningful name for a routing process. This name must be unique among all IP router processes for a given router. If the tag is not specified, the process is referenced with a null tag. The area tag of the IS-IS instance.

This is a number in the range if the router is configured with the metric-style narrow command or a number in the range 0 - if the router is configured with the metric-style transition or metric-style wide command.

Default value is The type of metric Narrow, Transient, Wide. The state of the neighbor up, down. Holding time, in seconds, for this adjacency. Identifier of the remote peer IP Address. Neighbor type Null, Client, Non Client. The ID of the network segment to which the neighbor belongs. The name of the interface used by the OSPF process.

The type of network to which the OSPF interface belongs. Initial delay to schedule an SFP calculation after a change, in milliseconds. Minimum hold time between two consecutive SPF calculations, in milliseconds. Maximum wait time between two consecutive SPF calculations, in milliseconds. The routers with which this router has IS-IS adjacencies. The interface on which the IS-IS is configured. Subnetwork point of attachment SNPA for the neighbor.
