Open Shortest Path First (OSPF) is an interior gateway protocol (IGP) designed expressly for IP networks. 
OSPF supports IP sub-netting and tagging of externally derived routing information, as well as supporting 
packet authentication and IP multicasting when sending/receiving packets. 
 
OSPF works best in a hierarchical routing environment. The first and most important decision on OSPF 
network is to determine area border routers (routers connected to multiple areas), and autonomous system 
boundary routers. At a minimum, OSPF-based routers can be configured with all the default parameter 
values, no authentication, and interfaces assigned to areas. If users intend to customize their networking 
environment, they must ensure coordinated configurations of all routers. 
 
To configure OSPF, complete the tasks in the following sections. After enabling OSPF, the other 
configuration tasks are optional. 
 

 
As with other routing protocols, enabling OSPF requires that you create an OSPF routing process, specify 
the range of IP addresses to be associated with the routing process, and assign area IDs to be associated 
with that range of IP addresses. Perform the following tasks, starting in global configuration mode. 
 

Step 1 Enable an OSPF routing process, which 
places you in router configuration mode. 

router-id router-id 

Step 2 Specify a routing process ID. A router ID is 
a 32-bit number in dotted-decimal notation. 

network prefix-length area 
{area-ID | area-address} 

Step 3 Define an interface on which to run OSPF 
and specify the area ID or IP address for that 
interface. 

 

 
The IC35516 OSPF conforms to the specifications in standard RFC2328. As there are a variety of 
implementations that support OSPF, the OSPF configuration depends on different type of routers. To 
configure OSPF on an Area Border Router (ABR), specify what type the router belongs to.
