Configuring OSPF
OSPF Configuration Examples
IPC-245
Cisco IOS IP Configuration Guide
In the following example, a 30-bit subnet mask is used, leaving two bits of address space reserved for
serial line host addresses. There is sufficient host address space for two host endpoints on a
point-to-point serial link.
interface ethernet 0
ip address 131.107.1.1 255.255.255.0
! 8 bits of host address space reserved for ethernets
interface serial 0
ip address 131.107.254.1 255.255.255.252
! 2 bits of address space reserved for serial lines
! Router is configured for OSPF and assigned AS 107
router ospf 107
! Specifies network directly connected to the router
network 131.107.0.0 0.0.255.255 area 0.0.0.0
OSPF Routing and Route Redistribution Examples
OSPF typically requires coordination among many internal routers, ABRs, and ASBRs. At a minimum,
OSPF-based routers can be configured with all default parameter values, with no authentication, and
with interfaces assigned to areas.
Three types of examples follow:
The first is a simple configuration illustrating basic OSPF commands.
The second example illustrates a configuration for an internal router, ABR, and ASBRs within a
single, arbitrarily assigned, OSPF autonomous system.
The third example illustrates a more complex configuration and the application of various tools
available for controlling OSPF-based routing environments.
Basic OSPF Configuration Examples
The following example illustrates a simple OSPF configuration that enables OSPF routing process 9000,
attaches Ethernet interface 0 to area 0.0.0.0, and redistributes RIP into OSPF, and OSPF into RIP:
interface ethernet 0
ip address 10.93.1.1 255.255.255.0
ip ospf cost 1
!
interface ethernet 1
ip address 10.94.1.1 255.255.255.0
!
router ospf 9000
network 10.93.0.0 0.0.255.255 area 0.0.0.0
redistribute rip metric 1 subnets
