Each router exchanges link state information with all neighbors physically attached to the same network segment. This table displays a summary of the link state for all adjacent neighbors. (Note that neighboring routers are discovered by this device via Hello messages.).
Parameter | Description |
IP Address | IP address of the neighboring router |
ID | The index number of the router interface to which this neighbor is attached. For |
| IP protocol, this value will always be zero. |
Router ID | The OSPF identifier for the neighboring router. |
Option | The optional OSPF capabilities supported by the neighbor. The neighbor's |
| optional OSPF capabilities are also listed in its Hello packets. This enables |
| received Hellos to be rejected (i.e., neighbor relationships will not even start to |
| form) if there is a mismatch in certain crucial OSPF capabilities. The OSPF |
| optional capabilities currently accepted include external routing capability and |
| TOS capability. |
| You need to map the binary bits to the supported options. For example, “3” |
| indicates both routing capability and TOS capability. |
Priority | The neighbor’s router priority. This priority is used in electing the designated |
| router for the area in which it exists. This value will be set to zero if this router |
| cannot be elected. |
