Configuring Routing

Figure 9-13. OSPF Neighbor Configuration

The OSPF Neighbor Configuration page contains the following fields:

Interface — Select the VLAN interface on which routing is enabled from the drop-down menu.

Neighbor IP Address — Select the IP Address of the neighbor for which data is to be displayed.

Router ID — A 32-bit integer in dotted decimal format that identifies the neighbor router.

Options — The optional OSPF capabilities supported by the neighbor. The OSPF Options field is

present in OSPF Hello packets, Database Description packets, and all link-state advertisements. The

Options field enables OSPF routers to support (or not support) optional capabilities, and to

communicate their capability level to other OSPF routers. Through this mechanism, routers of

differing capabilities can be mixed within an OSPF routing domain. The Options value is a bitmap,

and it signifies the capability of the neighbor.

Router Priority — Displays the OSPF priority for the specified neighbor. The 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 conversation. It indicates that there has been no

recent information received from the neighbor. On NBMA networks, Hello packets may still be

sent to Down neighbors, although at a reduced frequency.
