STEP FIVE
The CONFIG =>IP =>OSPF =>NEIGHBORS menu is required if the router uses OSPF over non-broadcast multi-
access interfaces such as X.25 and Frame Relay. If this is the case, set the parameters described in the following
table.
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 neighborin g 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 (Route r 1 in this
case) no longer passes OSPF info rmation.
Disable
deactivates neighbor link and erases
Neighbor’s IP
.
Neighbor's Priority Priority used by OSPF in multica st networks to elect the designa ted router. A priority of
1 will make this router the most likely to be chosen. A priorit y of 2 will make it second
most likely. Set it to 0 (zero) if this router should never be the desi gnated router. An
example can be seen in Area 1 i n the figure -- Router 1 shoul d never be the
Designated Router because it do es not have a direct link to Rout er 2. Either Router 0
or Router 3 should be chosen.
