Configuring OSPF
Configuring a Point-To-Point, Non-Broadcast OSPF Neighbor
You need to define a static OSPF neighbor to advertise OSPF routes over a point-to-point, non-broadcast
network. When an interface is configured as point-to-point, the following restrictions apply:
•
•
•
To define an OSPF neighbor on a point-to-point, non-broadcast network, perform the following tasks:
If the OSPF neighbor is not on a directly-connected network, create a static route to the OSPF neighbor.
Step 1
Do not use the default route. See the
information about creating static routes.
Define the OSPF neighbor by performing the following tasks:
Step 2
a.
b.
c.
Configure the interface through which the FWSM communicates with the neighbor by entering the
Step 3
following commands:
hostname(config)# interface vlan
hostname(config-if)# ospf network point-to-point non-broadcast
The following example shows how to configure OSPF across a point-to-point, non-broadcast network.
The OSPF neighbor is not on a directly-connected network, so a static route is needed.
hostname(config)# route ospf_outside 10.3.3.0 255.255.255.0 10.1.1.99 1
hostname(config)# interface Vlan55
hostname(config-if)# nameif outside
hostname(config-if)# security-level 0
hostname(config-if)# ip address 10.1.1.1 255.255.255.0 standby 10.1.1.2
hostname(config-if)# ospf network point-to-point non-broadcast

Every router within the same area must agree that the area is NSSA; otherwise, the routers will
–
not be able to communicate.
You can define only one OSPF neighbor for the interface.
You need to define a static route pointing to the OSPF neighbor if it is not on a directly connected
network.
The interface cannot form adjacencies unless neighbors are configured explicitly.
Enter router configuration mode for the OSPF process. Enter the following command:
hostname(config)# router ospf pid
Define the OSPF neighbor by entering the following command:
hostname(config-router)# neighbor addr [interface if_name]
The addr argument is the IP address of the OSPF neighbor. The if_name is the interface used to
communicate with the neighbor. If the OSPF neighbor is not on the same network as any of the
directly-connected interfaces, you must specify the interface.
If not already configured, define the networks and associated area ID for the interface facing the
OSPF neighbor by entering the following command:
hostname(config-router)# network addr mask area area_id
The addr mask pair must cover the IP address of the interface.
