Chapter 1 Configuring OSPF
Customizing OSPFv2
To specify area parameters for your network to configure an OSPFv2 NSSA, perform the following
steps:
Detailed Steps
Note OSPF does not support summary-address 0.0.0.0 0.0.0.0.
Command Purpose
Step 1
router ospf process_id
Example:
hostname(config)# router ospf 2
Creates an OSPF routing process and enters router configuration
mode for the OSPF routing process that you want to redistribute.
The process_id argument is an internally used identifier for this
routing process. It can be any positive integer. This ID does not
have to match the ID on any other device; it is for internal use
only. You can use a maximum of two processes.
Step 2
Do one of the following to configure optional OSPF NSSA parameters:
area area-id nssa [no-redistribution]
[default-information-originate]
Example:
hostname(config-rtr)# area 0 nssa
Defines an NSSA area.
summary-address ip_address mask
[not-advertise] [tag tag]
Example:
hostname(config-rtr)# summary-address
10.1.0.0 255.255.0.0
Sets the summary address and helps reduce the size of the routing
table. Using this command for OSPF causes an OSPF ASBR to
advertise one external route as an aggregate for all redistributed
routes that are covered by the address.
In this example, the summary address 10.1.0.0 includes addresses
10.1.1.0, 10.1.2.0, 10.1.3.0, and so on. Only the 10.1.0.0 address
is advertised in an external link-state advertisement.
