Configuring Network Types For Ospf Interfaces - Cisco ME 3400 Software Configuration Manual

Configuring OSPF
Beginning in privileged EXEC mode, follow these steps to configure routers that interconnect to
nonbroadcast networks:
Command
Step 1 configure terminal
Step 2
router ospf process-id
Step 3
neighbor ip-address [priority number]
[poll-interval seconds]
Step 4 end
Step 5 show ip ospf [process-id]
Step 6 copy running-config startup-config
On point-to-multipoint, nonbroadcast networks, you then use the neighbor router configuration
command to identify neighbors. Assigning a cost to a neighbor is optional.

Configuring Network Types for OSPF Interfaces

You can configure network interfaces as either broadcast or NBMA and as point-to point or
point-to-multipoint, regardless of the default media type.
An OSPF point-to-multipoint interface is defined as a numbered point-to-point interface with one or
more neighbors. On point-to-multipoint broadcast networks, specifying neighbors is optional. When you
configure an interface as point-to-multipoint when the media does not support broadcast, you should use
the neighbor command to identify neighbors.
Beginning in privileged EXEC mode, follow these steps to configure OSPF network type for an
interface:
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
no shutdown

Purpose
Enter global configuration mode.
Configure an OSPF routing process and enter router configuration
mode.
Specify an OSPF neighbor with neighbor parameters as required.
• ip-address—Enter the interface IP address of the OSPF
neighbor.
• (Optional) priority number—Specify the router priority value
of the nonbroadcast neighbor associated with the IP address. The
range is 0 to 255; the default is 0.
(Optional) poll-interval seconds—Specify a number that
•
represents the poll interval time (in seconds). This value should
be much larger than the hello interval. The range is
0-4294967295; the default is 120 seconds (2 minutes).
Return to privileged EXEC mode.
Display OSPF-related information.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enter interface configuration mode, and specify the Layer 3 interface
to configure.
Enable the interface if necessary. By default, UNIs and ENIs are
disabled and NNIs are enabled.
