21. OSFP
Configuration
Open Shortest Path First (OSPF) is a link-state routing protocol. It is designed to be run internal to a single
Autonomous System. Each OSPF router maintains an identical database describing the Autonomous System's
topology. Using this database, a routing table is calculated by constructing a shortest-path tree.
For more OSPFv2 information see
https://datatracker.ietf.org/doc/html/rfc2328
Global Configuration
The OSPF router configuration table is a general group to configure the OSPF common router parameters.

Parameter descriptions
:
OSPF Router Mode
: At the dropdown select to Enable or Disable the OSPF router mode. The default is Disabled.
Router ID
: The OSPF Router ID in IPv4 address format (A.B.C.D). When the router's OSPF Router ID is changed, if
there is one or more fully adjacent neighbors in current OSPF area, the new router ID will take effect after
restart OSPF process. Note that the router ID must be unique in the Autonomous System and value '0.0.0.0' is
invalid since it is reserved for the default algorithm.
Auto
: The default algorithm will choose the largest IP address assigned to the router.
Specific
: User specified router ID. The valid range is from 0.0.0.1 to 255.255.255.254.
Default Passive Mode
: Configure all interfaces as passive-interface by default. When an interface is configured
as a passive-interface, sending of OSPF routing updates is suppressed, so the interface does not establish
adjacencies (no OSPF Hellos). The subnet of all interfaces (both passive and active) is advertised by the OSPF
router.
Default Metric
: User specified default metric value for the OSPF routing protocol. The field is significant only
when the argument 'I
sSpecificDefMetric
' is TRUE.
Auto
: The default metric is calculated automatically based on the routing protocols.
Specific
: User specified default metric. The valid range is 0 to 16777214.
Static Redistribute Metric Type
: The OSPF redistributed metric type for the static routes:
None
: The static routes are not redistributed.
External Type 1
: External Type 1 of the static routes.
External Type 2
: External Type 2 of the static routes.
