IP routing advanced configuration
OSPF configuration
The Open Shortest Path First (OSPF) protocol is a link state Interior Gateway Protocol (IGP) used
to distribute routing information within a single autonomous system. If a host using OSPF detects
a change in the routing table or in the network, it immediately multicasts the change to all other
hosts in the network so that all hosts have the same routing table information.
Prerequisites for OSPF configuration
•
You must enable RRD before configuring OSPF (see
parameters" on page
•
You must enable global OSPF Status before configuring OSFP interfaces.

OSPF basic settings configuration parameters
The following section describes the parameters for configuration of OSPF basic settings located
Configuration, IP Routing, OSPF, Basic Settings tab
Variable definitions
The following table describes the variables and values for configuring OSPF basic settings.
Variable
OSPF Status
Router ID

140).
Value
Specifies the global status of the protocol in the router.
Select Enabled to enable the router to communicate with other OSPF
routers.
Select Disabled to disable the router from communicating with other OSPF
routers.
The default value is Disabled.
Type the router identifier. The router ID in OSPF has the same format as
an IP address but identifies the router independent of its IP address.
You can configure an arbitrary value for the IP address for each router;
however, each router ID must be unique. To ensure uniqueness, the
router ID must match with one of the router IP interface addresses.
