Area Menu (continued)
Area Range N Status | An Area Border Router (ABR) advertises link states for all networks within the area. |
| The number of such advertisements can potentially be reduced by condensing |
| different IP networks into a single range. |
Area Range N Net | Applies when Area Range N Status is Active. |
Address | Sets the network IP address for the range. |
Area Range N Mask | Applies when Area Range N Status is Active. |
| Sets the network IP mask for the range. |
STEP FIVE
The CONFIG =>IP =>OSPF =>NEIGHBORS menu is required if the router uses OSPF over
Neighbors Menu CONFIG=>IP =>OSPF =>NEIGHBORS
Parameter | Description |
|
Interface | Link for which neighbors will be defined. In the OSPF example, consider link 1 of |
|
| Router 3. |
|
Neighbor's IP | The router ID of the neighboring router. For Router 3, link 1, use the router ID of router |
|
| 1. |
|
Neighbor's Status | Enable includes link in OSPF database. |
|
| Enable Inactive leaves link in OSPF database, but router at end of link (Router 1 in this |
|
| case) no longer passes OSPF information. |
|
| Disable deactivates neighbor link and erases Neighbor’s IP. |
|
Neighbor's Priority | Priority used by OSPF in multicast networks to elect the designated router. A priority of |
|
| 1 will make this router the most likely to be chosen. A priority of 2 will make it second |
|
| most likely. Set it to 0 (zero) if this router should never be the designated router. An |
|
| example can be seen in Area 1 in the figure |
|
| Designated Router because it does not have a direct link to Router 2. Either Router 0 |
|
| or Router 3 should be chosen. |
